J784S4XEVM: Running Linux on an HS-FS processor

Part Number: J784S4XEVM


Hello,

For the needs of my project, I have replaced the processor of the J784S4XEVM evaluation board with an HS-FS processor.

I'm trying to run the latest Linux image provided in SDK 09.02.00.05 on this HS-FS processor.

Here are the steps I followed to try to make it work:

  • I flashed the SD card using the "create-sdcard.sh" script
  • I removed the tiboot3.bin in the boot partition
  • I copied the file "tiboot3-j784s4-hs-fs-evm.bin" (provided in the "boot-adas-j784s4-evm.tar.gz" archive) to the boot partition and renamed it to "tiboot3.bin"

Below is the terminal output when the board is powered up:

U-Boot SPL 2023.04-ti-gf9b966c67473 (Mar 19 2024 - 20:31:40 +0000)

SYSFW ABI: 3.1 (firmware rev 0x0009 '9.2.4--v09.02.04 (Kool Koala)')
Timeout during frequency handshake
### ERROR ### Please RESET the board ###

FYI, I was able to boot Linux on the GP processor and the switches on the board have not been modified at all.

Thank you for your support.

Best regards,

    This seems to be some DDR connection issue have you placed the HS-FS sample correctly.

    Thanks for your support.

    Closing this thread, as it is due to soldering problems on the HS-FS sample.
