TDA4VM: boot doesn't jump from TF-A to the linux Kernel.

update: checked the boot flow here http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components_U-Boot.html 

looks like there are two boot loaders ( u-boot SPL  -> TF-A -> u-boot ) . but still not sure why it is stuck here. 

Hi Sami,

is it TDA4 EVM or custom board?

Which boot media (SD card, SPI, NAND, Ethernet ...) you use?

Yordan

Hi Yordan,

Thanks for the response. 

It is TDA4EVM 

I use SD Card.

What should be the next stage after the logs? 

Best Regards

Hi Sami,

The bootlog should look like this:

I/TC: OP-TEE version: ti2019.02-89-ge5a8779-dev (gcc version 8.3.0 (GNU Toolchain for the A-profile Architecture 8.3-2019.03 (arm-rel-8.36))) #1 Thu Oct 24 03:52:22 UTC 2019 aarch64

I/TC: Initialized

Detected: J7X-GESI-EXP rev E2

Detected: J7X-VSC8514-ETH rev E2

Have you created the SD card according to this instructions:

Can you check if you have tiboot3.bin, tispl.bin, u-boot.img, sysfw.itb, uEnv.txt files on the "boot" partition of the SD card?

Yordan

Hi Yordan,

My boot log looks like this. It is reverse (first I see u-boot log and then ATF). 

U-Boot SPL 2019.01-00001-g66126341c8-dirty (Mar 10 2020 - 10:53:57 +1030)

  Yes I have created SD Card. and I have all these files in the SD card in "boot" partition.

  Can you please share the full boot log. (from start to the to the kernel logs). 

Best Regards

Hi Yordan,

I think the boot should first execute ATF -> U-Boot -> Kernel . 

as per the Boot Flow here:

http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components_U-Boot.html

Looks like the U-Boot is  blocked in some loop but I am not sure which code it is running.

I don't see any logs from U-Boot after ATF/OP-TEE logs. 

Any Idea how to proceed from here. 

Best Regards

Sami

Hi Sami,

Did you progress further? Do you need any help on this? Let me know.
You should be able to get to u-boot prompt without any issues using the steps
suggested by Yordan.

Keerthy

Thanks, It is working now.

Best Regards

Sami
