Part Number: AM3352 Tool/software: Linux Hi , We've design TI_ AM3352 's USB Port0 as client mode for our project , but it can't recognized by HOST PC(Windows) . I've check the USB_ID , it's connect to MicroUSB directly . And I've measure the voltage of USB0_VBUS is 5V when we plug USB Cable into Host PC side. ======================= I've attach the log file : "putty_20181222_1.log" , Do you have any suggestion ? I guess Host PC should be pop something in Windows Device Manager , right ? Thanks.

Forum Post: RE: RTOS/TDA2P-ACD: CAN FD : Not able to transmit CAN FD frames
Hi, Another query in the same context. We wanted to know what is the exact dlc to be set to transfer a data buffer with 64 bytes of valid data ? When transmitting classic CAN frame, dlc was set to 8 bytes and for CAN FD frame, dlc was set to 64. In the mcan.c file in csl, in the API "uint32_t MCAN_getDataSize(uint32_t dlc)" at line 1834, datasize array is defined only for 16 DLC's. uint32_t dataSize[16] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 20, 24, 32, 48, 64}; (at line 1836 of mcan.c file ) Are these the only valid values to be set to dlc while transmitting CAN frame ? i.e. If we want to transmit data with some different data lengths (say 18 bytes ), then will we have to define a new dlc in the dataSize buffer ? or should we use the nearest dlc present in the dataSize buffer ? Regards, Amol

Forum Post: AM3352: Calibration of DDR3 PHY FIFO WE slave ratio (aka gate leveling)
Part Number: AM3352 I have spent some time trying to understand the details of the calibration done with the DDR3_slave_ratio_search_auto.out binary. There are just two things that I don't fully understand: 1) On our board the DATA_PHY_FIFO_WE_SLAVE_RATIO search finds a minimum value of 0 and a maximum value of about 0x154, resulting in a final value of 0xAA. Why is a minimum of 0 considered valid if the maximum is found to be more than one full clock cycle away? As far as I know any minimum less than the maximum minus tRPRE is wrong. In my case it still works because the average of minimum and maximum is less than tRPRE away from the maximum. But it is suboptimal since it is not centered within tRPRE. 2) The Ratio Seed spreadsheet calculates a seed value for DATA_PHY_FIFO_WE_SLAVE_RATIO that is twice as sensitive to the DQS length than to the CK length. Why? The FIFO WE slave ratio has to compensate for the time it takes the read command to travel from the CPU to the RAM chip and for the time it takes the result to travel back to the CPU. There is no second transfer on the DQ(S) lines starting after the result has arrived that has to be taken into account in the formula. The equivalent spreadsheet for Keystone I processors (SPRABL2) uses a different formula where DQS length and CK length have equal weight. Is the formula in the AM335x spreadsheet wrong?

Forum Post: RE: RTOS/AM3358: Which start files should be used to support TI-RTOS?
Thanks! External interrupt can be handled normally for the RTOS sample application, the IRQ exception handler must have been replaced in the RAM vector address . So the IRQ exception handler has been implement in the project and i don't need do it again for IRQ exception. Am i right? For other type exception, I need costumize these below handler functions: const UInt32 ti_ sysbios _family_arm_a8_intcps_Hwi_vectors[] __attribute__ ((section (".vectors"), aligned (0x400))) = { ...... /* resetFunc */ (UInt32)(&_c_int00), /* c_int00 */ /* undefInstFunc */ (UInt32)(&ti_ sysbios _family_arm_exc_Exception_excHandlerAsm__I), /* swiFunc */ (UInt32)(&SVC_Handler), /* prefetchAbortFunc */ (UInt32)(&ti_ sysbios _family_arm_exc_Exception_excHandlerAsm__I), /* dataAbortFunc */ (UInt32)(&ti_ sysbios _family_arm_exc_Exception_excHandlerDataAsm__I), /* reservedFunc */ (UInt32)(&ti_ sysbios _family_arm_exc_Exception_excHandlerAsm__I), /* irqFunc */ (UInt32)(&ti_ sysbios _family_arm_a8_intcps_Hwi_dispatchIRQ__I), /* fiqFunc */ (UInt32)(&ti_ sysbios _family_arm_a8_intcps_Hwi_dispatchFIQC__I) } In order to trigger data about exception, i write code as below in the main function , int main(void) { ...... appTasksCreate(); *((int *)0x80000001) = 0x12345678; /* trigger data abort */ /* Fourth step is to Start BIOS */ BIOS_start(); ) But no exception happen.

Forum Post: AM3358: AM335x GPMC burst behavior
Part Number: AM3358 Dear TI Experts, I have an FPGA attached to the GPMC bus of an AM3358 device and I am currently working on the FPGA side. To achieve maximum performance, the FPGA logic supports bursts of 16x16bit words. ATTACHEDDEVICEPAGELENGTH parameter is set accordingly in the GPMC configuration. Bursts are generated using the eDMA engine. Sometimes I just need to read a single 16-bit register from the FPGA, which should be possible issuing a single memory access from the Cortex-A8. However, it is not clear how the GPMC will perform the external access in this case. From AM335x TRM: 7.1.3.3.10.5 System Burst Versus External Device Burst Support “When the system burst request length is less than the ATTACHEDDEVICEPAGELENGTH value, the GPMC proceeds with the required accesses.” What "required access" means in this case? Should I expect a full burst (then the GPMC returns the requested word to the CPU)? Or only a single access is performed? Thank you very much.

Forum Post: AM3358: AM3358 stops sending C character after 5 times
Part Number: AM3358 Dear all, I would like to ask support about an issue I have using the AM3358BZCZ100 on my self designed board (produced by external company). When I connect my laptop to the serial port of the CPU I can see that it's sending a C character for 5 times. After 5 times it stops. When I connect the reset pin from the CPU (not the power chip) to the GND for a seconds, then after it's sending the C character again for only 5 times. I do not have any SD card inserted which it could boot from. I use the power IC TPS65217BRSLT. (Please visit the site to view this file) Below I have the measured voltages using the signal names from the drawing which can be found here: (Please visit the site to view this file) VDDS_DDR = 1,84v VDD_MPU = up and down from 1,12v to 1,08v VDD_CORE = 1,08v VDD_3V3A = 3,36v VDDS = 1,8v VDD_3V3AUX = 3,32v PMIC_POWER_EN = 1,8v PMIC_PGOOD = 1,8v LDO_PGOOD = 1,8v VDD_PLL = 1,8v SYS_RESETN = 3,28v Does anyone have an idea what could be the root cause? Thank you in advance.

I can find a description: Global.ndkTickPeriod = 100 in the cfg script editor, but I can not find where it be set by the XCONF.

Forum Post: Linux/TMDXIDK5718: How SPL can read EEPROM behind Mux on I2C bus 2
Part Number: TMDXIDK5718 Tool/software: Linux Hi I'm using Linux SDK 5.1, custom HW, strongly based on IDK574. I have EEPROM (chip address 0x51) on I2C bus 2 behind an pca9546 (chip address 0x70) on channel 1 (In IDK, EPROM and PMIC are both on I2C bus 0.) I can successfully read eeprom in U-boot as follows: Setting bus 2: i2c dev 2 setting channel 1 on mux: i2c mw 70 0.1 1 Read 400h bytes: i2c md 51 0.2 400 Now I tried to do same in do_board_detect() of SPL. int save = i2c_get_bus_num(); // save the bus number because later in board_late_init() we have to talk to bus 0 again gpi2c_init() rc = i2c_set_bus_num(i2c_bus /* 2 */); if (rc) return rc; // set mux to channel 1 uint8_t buffer = 1; // channel 1 rc = i2c_write(0x70, 0, 0, &buffer, 1); // here I always get return code 1 if (rc) return rc; rc = i2c_probe(0x51); if (rc) return rc; rc = i2c_read(0x51, 0x0, 0x2, (uint8_t *)ep, sizeof (struct my_eeprom)); if (rc) return rc; i2c_set_bus_num(save) ; // restore bus number So How I can I use bus number 0 in SPL? Do I have to add the mux and EEPROM in devicetree? I just enabled i2c2: &i2c2 { clock-frequency = ; u-boot,dm-spl; status = "okay"; }; Or do I have to set CONFIG_SYS_OMAP24_I2C_SLAVE or some other CONFIG_? BR, Chris

Forum Post: RTOS/PROCESSOR-SDK-AM437X: which include statement should be deleted when migrating the non-BSD socket API to the the BSD socket API.
Part Number: PROCESSOR-SDK-AM437X Tool/software: TI-RTOS Hi, By the SPRU524J, we can use the BSD socket API and non-BSD socket API. if we use the BSD socket API, we need to use the follow statement: #include but I have a example code which seem to use the non-BSD socket API, but the manual do not mention the include statement about the non-BSD socket API. so I do not know which statement should be deleted, when I migrate the non-BSD socket API to the the BSD socket API.
