J784S4XEVM: NAND Flash Boot on J784S4XG01EVM

Hi Adnan,

What Bootloader are you trying to use?

regards

Suman

I have built the default Processor SDK Linux image successfully and was able to boot the board from both SD card and eMMC using the generated image.

Now I am trying to boot the board using the NAND flash interface. 

Below are my bootloader binaries

 ls
EFI          tiboot3-j784s4-gp-evm.bin     tispl.bin
Image        tiboot3-j784s4-hs-evm.bin     u-boot.img
tiboot3.bin  tiboot3-j784s4-hs-fs-evm.bin  uEnv.txt

I will have our U-Boot Flash support engineer get back to you on this thread further.

Hi Adnan,

Please refer to the SDK documentation for this.

https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-j784s4/11_02_00_04/exports/docs/linux/Foundational_Components/U-Boot/UG-QSPI.html

Instead of using tftp to copy the image to the load address, you can use fatload to read the data from the SD/MMC card, and then use the sf command to flash it to the OSPI.
