Forum Post: Linux/AM3356: System no more booting properly after sw update
Part Number: AM3356 Tool/software: Linux Hello everybody , in my system we have a MMC soldered on the board . everything is working fine than I do a SW update ( hereunder all infos ) and in some cases ( about 1% of sw update ) system is no more capable to boot ( you see CCCC on the serial , so even MLO is not loaded properly ) . we found this issue since for quality heavy testing is done to be sure SW upgrade is bulletproof . when system is not working ( not booting ) , I booted using NFS and all files are there with proper MD5 checksum. one extra info : If I change only uEnv.txt druing the update the system update will always work ( so not touching MLO and uboot.img system will always work) . here is my partition table and my sequence: P1 boot (MLO u-boot.img, uEnv.txt) FAT32 about 64MB P2 RootFS1 ext4 about 256MB P3 RootFS2 ext4 about 256MB P4 Data ext4 3500mb system is up and running on P2 , I do an update using a script like this : 1) copy a new MLO & u-boot.img, in P1 2) untar a tar.gz rootFS in P3 3) mark uEnv.txt to enable P3 as rootfs 4) reboot ( both HW or SW same results ) . all the previous is working about 99% of the time ... please any suggestion is welcome thank you regards Carlo

Forum Post: RE: Linux/AM5728: PCIe EP reference clock
Hi, CY, I need to get some background info first. Is your board design based on AM5728-IDK or AM5728 GP EVM? In (1), when you refer to the AM5728 EVM, do you mean your custom board or TI EVM? That is, when 2 AM5728 EVM are connected, are both TI EVMs or both your boards? The registers change seems to be correct. I do know that I can't verify the RX mode on TI EVM without hardware modification. For Tx mode, if I remember correctly that on TI GP EVM, I need to remove C426 and C427, and the parallel 100 ohm resister between ljcb_clkn and ljcb_clkp. Both ljcb_clkn and ljcb_clkp should be independently terminated to GND with 50 ohms. The same should apply if it is based on AM5728 IDK but at C438 and C439. Rex

Hello Lucas, The PHY addresses are part of EVM.c in the uboot (board\ti\dra7xx\evm.c). Search for cpsw_slaves structure which has phy_addr as one of field.

Forum Post: RE: Linux/AM5728: 4GB DDR test from U-boot
Make sure you enabled LPAE in your configs/am57xx_evm_defconfig file. I looked in the latest SDK and it is enabled by default CONFIG_ARMV7_LPAE=y I also noticed that in include/configs/am57xx_evm.h, only this is set #define CONFIG_NR_DRAM_BANKS 2 In the include/configs/dra7xx_evm.h there are two other CONFIGs set in addition to this one. #define CONFIG_VERY_BIG_RAM #define CONFIG_NR_DRAM_BANKS 2 #define CONFIG_MAX_MEM_MAPPED 0x80000000 Can you modify your am57xx_evm.h to include these two others? We boot to Linux and use memtester to test memory. Can you do that instead of in u-boot? Steve K.

I couldn't compile any package that depends on xorg because I get following error in bitbake: ERROR: openbox was skipped: missing required distro feature 'x11' (not in DISTRO_FEATURES) I tried to add that feature in conf/local.conf but it didn't change anything. Will be support for that added in foreseable future?

well making those changes did not fix my ping issue. i am assuming there is something wrong with the library rebuild. i am told that this project is no longer going to be worked on until further notice. maybe we will take another look at it when the next SDK is released - but if i can ping with that one but can't do DHCP, TCP connections on a router it holds no hope either. thank you for your help.

Forum Post: RE: RTOS/PROCESSOR-SDK-AM335X: Hooks structure customization
Hi Christopher, First, can you confirm that the GNU reentrant hooks are there without you adding them. They should be added automatically unless there are certain situations (e.g. Tasking is disabled, zero size heap, you explicitly disable the reentrancy in the .cfg file). If they are not automatically being added, please let me know what version of SYS/BIOS, XDCtools, NDK and compiler you are using. Second, the section in the UG section "Configuring the NDK with C Code (without XGCONF)" means you are not using the XDC configuration capabilities of the NDK. You still need the .cfg file since you are using TI-RTOS . I do agree that this could be clarified more. Third, I'm not following your logic on not wanting to use the configuration options in the NDK. Without it, you are still using the NDK libraries (I'm assuming you are not pulling in all the NDK source into your application). Todd
