Hi Kemal, This fix didn't work for my particular issue but I found the root cause. I discovered that using "sudo make linux" to build out the linux kernel did work OK. This led me to think that there might be an environment configuation issue. Doing "which perl" under both root and build user showed that root was using /usr/bin/perl while the build user was using perl from the sysroot folder because of the step to include the cross compiler in the path... dmurphy@tibuilder:~$ sudo which perl /usr/bin/perl dmurphy@tibuilder:~$ which perl /home/dmurphy/ti-processor-sdk-linux-am57xx-evm-04.01.00.06/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/perl So putting /usr/bin at the beginning of $PATH appears to work OK for me. I guess the root cause is possible "environment contamination" from processors.wiki.ti.com/.../Processor_SDK_IPC_Quick_Start_Guide which requires cross compiler to be added to $PATH when building out ti-ipc_linux? Thanks, Dermot

Hello Marek, I'm going to mark this resolved. Please comment if you need additional support. Regards, Nick

Hello Frank & Annette, I am going to mark this resolved. If there is any additional assistance we can provide, please comment! Regards, Nick

Your installation and display of the graphical configuration tool (XGCONF) looks correct. The RTOS kernel is designed to be used with XGCONF so that the appropriate module in the SYSBIOS kernel can be added and removed from the .cfg file using a graphical interface. The PDK doesn`t necessarily require this graphical interface, there are usually libraries that can be linked into the application. Typically, you will see the XGCONF GUI when you open a RTSC configuration file (.cfg). You can read more about XGCONF in the BIOS Users Guide, which can be found inside the SYSBIOS installation directory.

I will do an Android build on my side and see if I can replicate your results. Did you make any modifications before getting the external/libcxx/include/chrono:386: error: undefined reference to '__mulodi4' error? Or were your modifications only to add libcompiler_rt? Regards, Nick

Zewei, To create/build the dual mac project for AM572x, you need to install AM572x Processor SDK. Since the AM335x and AM572x share the same driver source, you can find the project files in the AM335x Processor SDK though, see pdk_am335x_1_0_9\packages\ti\transport\ndk\nimu\example\am572x\armv7\bios\NIMU_DualMacExample_idkAM572x_armExampleproject.txt .

Part Number: AM5708 Tool/software: Linux AM5708 Processor SDK Linux 4.02 I have some questions pertaining to the PRU EMAC driver: Does the PRU firmware touch the MDIO in any capacity, or is that purely managed by the Cortex A15 and Linux? How does the "link lost" alert get managed? Is the PRU involved somewhere? Is there any kind of configuration that needs to be specified relating to the PHY? (PHY-specific data needed by the PRU?) Thanks, Brad

Thanks for the archived reference. I made the changes to menuconfig. And see both /drivers/cpufreq/cpufreq-cpu0.c and /board-support/linux-3.14.43+gitAUTOINC+875c69b2c3-g875c69b/arch/arm/mach-omap2/opp33xx_data getting built. But am a little confused about the device tree file. How do I know if the above files parse the DT file? >> cpu0-supply = ; And from the Wiki, is this the correct value for cpu@0 node for a Beaglebone Black? And though the Wiki mentions an opp-modifier table in the same file (am33xx.dtsi), don't see any mention of opp in the dts directory when greepping /board-support/linux-3.14.43+gitAUTOINC+875c69b2c3-g875c69b/arch/arm/boot/dts How do we get /cpufreq/scaling_setspeed working? (I can also test on an AM335x EVM if that is easier).

Part Number: AM5708 Tool/software: Code Composer Studio On my custom AM5708 board, I have two target configurations. One works and the other one doesn't. The error I get from one configuration is this : According to JTAG debug wiki [1], this could be hardware issue. Hence I am compelled to get to the bottom of this even though my 2nd configuration seems to work ok. As the message suggest, I slowed down the JTAG speed as well. It doesn't help. Can someone think of what may have resulted in this error? I can't tell the difference between my two configurations.

Hello Mike, Processor SDK 04.02 and Processor SDK 4.2 are the same thing. When the PRU SW Support Package was first introduced, users had to download it separately on TI.com and then add it to the Processor SDK. Nowadays, it is automatically included in the Processor SDK at (e.g.) ti-processor-sdk-linux-am335x-evm-04.02.00.09/example-applications/pru-icss-5.1.0. So if you're using the PRU SW Support Package in Processor SDK 4.2, then the PRU SW Support Package version is 5.1.0. As far as modules go: as long as you are 1) building the Linux Kernel with RPMsg support and building the modules as per the RPMsg Quick Start Guide , 2) installing the modules into the filesystem as per the Quick Start Guide , you should be able to see /dev/rpmsg_pru*. I think but am not sure that simply using ti-processor-sdk.../bin/create-sdcard.sh is sufficient to see rpmsg_pru as well. I would be surprised if you got the Hello World messages but were unable to see the pru modules. The PRU should only echo back if PRU channels have been established as in the PRU_RPMsg_Echo_Interrupt0/main.c : /* * Using the name 'rpmsg-pru' will probe the rpmsg_pru driver found * at linux-x.y.z/drivers/rpmsg/rpmsg_pru.c */ #define CHAN_NAME "rpmsg-pru" #define CHAN_DESC "Channel 30" #define CHAN_PORT 30 Something to note is that I believe Lab 5 expects CHAN_NAME to be "rpmsg-client-sample" while the Quick Start Guide expects it to be "rpmsg-pru". I'm not sure if that could be causing problems for you. Regards, Nick

I spent days in Hyperlynx getting the DDR3 and other I/O tuned in the layout. Then the FW engineer spent days getting the DDR3 settings right in the kernel. I'm happy with that. That said, we are on a hunt for an intermittently bad signal, especially power sequencing and resets.

Part Number: PROCESSOR-SDK-AM335X Tool/software: Linux We are using an external ADC chip (TI ADS127L01 ) with McASP connection to an Octavo part with AM3358 processor. We are using the ADC chip as a McASP Master (AM335x as slave) and we are struggling to find any reference for both setup of the device tree and an example user mode app for McASP FIFO read. The ADC is being used to measure voltage from an analog accelerometer. Our board is utilizing the following McASP0 to ADC pin mapping: (B12) mcasp0_aclkr for SCLK (AM335x input from ADC bit clock) (C13) mcasp0_fsr for Frame Sync ((AM335x input from ADC word clock) (D13) mcasp0_axr1 for Data (AM35x input from ADC DOUT). Note that we are not using the ADC DIN line as no ADC codec control is required, we will simply enable the chip to start streaming (handled via GPIO - which we have full control of now). First - the device tree. This is the last board peripheral that we will interface to. We have been using a BBBW ref BSP elements. All device tree entries are within the am335x-bone-common.dtsi file. Specific entries for McASP0 are: { cpus { cpu@0 { cpu0-supply = ; }; }; memory { device_type = "memory"; reg = ; /* 256 MB */ }; vmmcsd_fixed: fixedregulator@0 { compatible = "regulator-fixed"; regulator-name = "vmmcsd_fixed"; regulator-min-microvolt = ; regulator-max-microvolt = ; }; ocp { mcasp0: mcasp@48038000 { compatible = "ti,am33xx-mcasp-audio"; ti,hwmods = "mcasp0"; reg = , ; reg-names = "mpu", "dat"; interrupts = ; interrupts-names = "rx"; status = "okay"; op-mode = ; /* operational mode - 0 -> I2S mode, used for I2S, PCM and TDM protocols */ tdm-slots = ; /* Number of TDM slots */ num-serializer = ; serial-dir = ; /* 0:INACTIVE, 1:TX, 2:RX */ rx-num-evt = ; dmas = ; dma-names = "rx"; }; }; }; &am33xx_pinmux { pinctrl-names = "default"; pinctrl-0 = ; ... mcasp0_pins: mcasp0_pins { pinctrl-single,pins = ; }; }; &mcasp0 { pinctrl-names = "default"; pinctrl-0 = ; status = "okay"; }; The above entries compile just fine (to dtb file), but without user mode code to execute, it is difficult to say if it works. All referenceable ALSA examples that I can find utilize an audio codec driver as shown in the TI Sitara Audio Driver Overview here: http://processors.wiki.ti.com/index.php/Sitara_Linux_Audio_Driver_Overview ... but these codecs all support both a Control Interface (Codec Driver) and Data Transfer Interface (Platform Driver). Our circumstance is unique in that we will only use the Platform Driver API. The same Sitara Audio Driver site lists the following Platform Driver interface: https://git.ti.com/ti-linux-kernel/ti-linux-kernel/blobs/ti-linux-3.12.y/sound/soc/davinci/davinci-mcasp.c ... but I cannot find any example client that uses this API. It would be extremely helpful to: 1. Understand if a better approach makes sense (considering our single, unidirectional McASP connection with no control interface). 2. Understand if our device tree makes sense (we cannot find an example without control interface elements). 3. If our approach is OK, where can we find a referecable user mode example for reading an incoming FIFO from the Platform Driver API. Thanks in advance to any repliers. Regards, Mark J

Part Number: AM5728 I'm evaluating a first article PCB from a new-ish supplier to us. The board doesn't get to the point of booting the Linux kernel, but it does get through the first few seconds of booting to an SD card, so a bunch of stuff must be working. The debug messages complains "smps8: failed to apply 1800000uV constraint(-22)" followed by these: [ 0.461407] palmas-pmic 48070000.i2c:tps659038@58:tps659038_pmic: failed to register 48070000.i2c:tps659038@58:tps659038_pmic regulator [ 0.462072] palmas-pmic: probe of 48070000.i2c:tps659038@58:tps659038_pmic failed with error -22 So I've been probing around the PMIC, and stumbled into finding the 1.8V is only about 1.69V, which is below the 1.71V lower limit. The signal on the PMIC side of the inductor is really erratic, suggesting to me that it's struggling to put out enough current. I have good versions of this board from another CM, and the PMIC output on this one looks solid. The processor on New CM's 1st article also gets a little warmer than the current CM. So I concluded that something is sucking extra 1.8V. Are there versions of am5728 that consume more current on the 1.8V rail than version 2.0? Is there a potential sneak circuit here that's pulling juice from 1.8V? Just for fun, here are scope shots. First one is from the new CM's board, second is from current CM's board. Any thoughts from the forum would be welcome. BR Mike

Great new! [quote user="Prasad Jondhale"]1. How is IPv6 link local address generated? Is this fixed from configuration? If needs to be changed how it can be done?[/quote] The link local address is generated automatically from the MAC address. All IPv6 interfaces *must* have this (it is an IPv6 requirement) and it must be assigned automatically, which the NDK does for you. Note that this address is not routable. For more info, see the wikipedia page , under IPv6. [quote user="Prasad Jondhale"]2. I see DHCP for IPv4 and static IPv6. Hope that is correct and both needn't be always static[/quote] See above answer. [quote user="Prasad Jondhale"]3. We are calling deinit function in the netclose hook. Isn't it called from NDK stack? Is similar call needs to be done for IPv4?[/quote] The user must call the IPv6 init and deinit APIs, this is not necessary for IPv4. IPv6 was added many years after the NDK was first written, and was designed to be enabled at run time like this. [quote user="Prasad Jondhale"]4. Can you please share code for tcpHandler? I think i will keep this for testing IPv6 TCP traffic.[/quote] You can download this from resource explorer in CCS: Steve

Nick, Ok on the SDK 04.02 = 4.2 ... I wasn't sure since you weren't using the 2 digits...thought you may have meant 4.20 perhaps. Yes, I am using 5.1.0 since I have the 04.02.00.09 TI SDK. I have used the create.sdcard.sh, but prefer to TFTP boot and NFS mount my rootfs for faster development and debugging;-) I am getting the 100 'Hello World' messages and see this showup in dmesg and on the console/shell from my UART. Here is why I do not think you need to have /dev/rpmsg-pru* In the main.c file of PRU_RPMsg_Echo_Interrupt1 for 5.1.0 it says this: /* * Using the name 'rpmsg-client-sample' will probe the RPMsg sample driver * found at linux-x.y.z/samples/rpmsg/rpmsg_client_sample.c * * Using the name 'rpmsg-pru' will probe the rpmsg_pru driver found * at linux-x.y.z/drivers/rpmsg/rpmsg_pru.c */ #define CHAN_NAME "rpmsg-client-sample" //#define CHAN_NAME "rpmsg-pru" #define CHAN_DESC "Channel 31" #define CHAN_PORT 31 As you can see, the rpmsg-pru channel name is commented out. Then if you look at the rpmsg-client-sample.c file, found at the above commented location, the rpmsg_sample_probe does not create or look for any /dev/rpmsg-pru* devices. These are used only when channel name is "rpmsg-pru." So, different probe functions get called depending on which CHAN_NAME you are using. Digging in a little further, the rpmsg_device struct seems to use a different way to communicate via endpoints and I never see anything in the linux-x.y.z/drivers/rpmsg_core & other files that suggest needing or using device files rpmsg-pru* My initial problem as the original poster stated was that we should see /dev/rpmsg-pru* device files and I associated this for the example programs and rpmsg-client-sample kernel module not working. However, my issue wasn't that the /dev/rpmsg-pru* files were missing but rather previous version of the PRU SW Support Package (and rolled into the AM335X SDK) were using system events for mailboxes around the 59 range. However, the newer examples use system events 16-19 for mapping events to channels. Also, the code snippet indicates that rpmsg-client-sample.ko is used instead of rpmsg-pru. Anyways, hope this is becoming clearer and others that perhaps fall into this can see. Thanks! -Mike T

Good, many thanks, Yordan I missed this part. Thanks Jackie
