TMDSEVM572X: EVM doesn't start

Ilya Afanasiev

Part Number: TMDSEVM572X

My board don't load sbl from the SD card and from the UART3. When I push the power button power led lights, but after few seconds it ceases to glow.

When I set J5 and load sbl from JTAG it starts, but stop in function boardPadIoIsolation, step:

while ((uint32_t) 0x0 != CSL_FEXT(devPrm->PRM_IO_PMCTRL_REG, DEVICE_PRM_PRM_IO_PMCTRL_REG_ISOCLK_STATUS));

It worked in the past. I don't know what happened. Please, help me.

What software are you trying to load?

I trying to load SBL from the ti-rtos-sdk and any of the examples as main application.

Thanks. I will ask the RTOS team to check this. They will respond here.

Hi,

Can you remove the SD card from slot and use CCS/JTAG to connect to A15_0, the GEL will do the intilization processors.wiki.ti.com/.../AM572x_GP_EVM_Hardware_Setup Keep in mind the PMIC shutdown issue discussed in previous section while connecting to the target cores. Due to the PMIC shutdown issue, users need to connect to A15_0 as soon as you push the power button to enable power to the SoC.

Does this work?

Ilya,

Can you specify if you used the same SD card before?? If this is a new SD card, have you formatted to FAT32 before copying the MLO and application image? You should only set J5 if you want to run the GEL and run the application.

Can you run GEL and UART driver example application as a test. It is unclear why the code hangs in boardIOIsolation. Is this using default SDK package or have you made any modifications to the board or SBL software?

It may also be recommended to run the diagnostics code on the EVM to check for basic functionality.

No, it don't work :(

I use default SD card with default FS and default SBL from SDK. When I run application by JTAG/CCS I set J5.
I run GEl and UART example and DIAG apps, but they don't work too.

When I set J3, J4, J6 to boot from UART, I must get from UART ASIC ID(see 33.3.5 Peripheral Booting), but it don't occur.
If I use board lib without IO_DELAY and with NO_IO_DELAY define (without isolation), than pins like uart3_tx/rx, user leds and others, don't work.

Please, help me. :(
