Hi Expert,

My SDK IS ti-processor-sdk-linux-j7-evm-08_01_00_07

platform is J721EXSOMG01EVM+J721EXCP01EVM

I make the SD card by the the command:

sudo ./mksdboot.sh --device /dev/sdc* --sdk ~/ti-processor-sdk-linux-j7-evm-08_01_00_07

And I can see the successful message:

Partitioning and formatting completed!
Copying filesystem on /dev/sdc1, /dev/sdc2
unmounting /dev/sdc1, /dev/sdc2
completed!

But EVM cannot boot up and show the message:

U-Boot SPL 2021.01-g15769936a5 (Dec 20 2021 - 17:09:03 +0000)
Model: Texas Instruments K3 J721E SoC
Board: J721EX-PM2-SOM rev E8
SYSFW ABI: 3.1 (firmware rev 0x0015 '21.9.1--v2021.09a (Terrific Lla')
Trying to boot from MMC2
spl_load_image_fat: error reading image tispl.bin, err - -6
spl: no partition table found
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###

Do I miss anything?

Thanks

Hi Daniel,

Did you face similar issues with older SDK? Or this is the first time you are trying on this board?

I would recommend trying the same with another SD card and another board if available.

Hi Keerthy

follow the instructions to modify DDR4 setting in u-boot source codes as e2e link:

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1047077/tda4vm-tda4vm-som-ver-e8a-ddr-queestion

rebuild u-boot and replace new boot files to make EVM work.

cd $PSDKL_PATH
make u-boot
cp board-support/u-boot_build/a72/tispl.bin board-support/u-boot_build/a72/u-boot.img board-support/u-boot_build/r5/tiboot3.bin /media/$user/boot
sync

Thanks

Daniel
