TDA4VE-Q1: OSPI mode sbl boot linux Startup exception

gg yang said:

0.000000] [Firmware Bug]: Kernel image misaligned at boot, please fix your bootloader

This is not a fatal error.

I have more questions to understand the issue better:

1. What is boot flow?
2. Is this a custom board or TI EVM?
3. Is the error happening always or only certain iterations?
4. Also paste the full failure logs.

Best Regards,

Keerthy

Booting Linux via OSPI
            goto <PDK>/packages/ti/boot/sbl/example/boot_app/scripts
            Run ./make_multicore_appimages.sh <board_name>
            Multicore images(lateapps) will be generated in <PDK>/packages/ti/boot/sbl/example/boot_app/binary/$BOARD/. Stage1 image corresponds to multicore_MCU2_0_MCU2_1_stage1.appimage, stage2 image corresponds to multicore_DSP_1_2_C7x_MCU3_0_MCU3_1_stage2.appimage and so on.

2. custom board.

If changed to the following, start normal 

sbl-->boot_app_ospi_linux_j721s2_evm_mcu1_0_freertos_TestApp_release.appimage--->atf_optee.appimage ----->ti_uboot_spl.appimage---->uboot.img--->kernel---->rootfs

3. error happening always

The above is the main failing function. Have you made changes to the reserved memory section in the device tree?

SD card mode, Boot in uboot normally,

Then, converting the dtb Image to an appimage file and bootup it with mcu bootApp in OSPI mode will result in an exception.

When I modify dts to the following, the OSPI startup kernel will fail, while the modified SD card startup will not fail

Hi,

Can you make sure that dtbs are loading correctly when you boot from ospi?

Just compare the phase where the Linux and dtbs are loaded.

Also can you try with default SDK and check if ospi boot works well?

Best Regards,

Keerthy 

Hi.

I can confirm that it is correct.

You can also boot using the default one, as using OSPI to boot Linux requires adding k3-j721s2-vision apps. dtbo to k3-j721s2-common proc board.dtb, but there are also exceptions after adding it

gg yang said:

changed to the following, start normal 

sbl-->boot_app_ospi_linux_j721s2_evm_mcu1_0_freertos_TestApp_release.appimage--->atf_optee.appimage ----->ti_uboot_spl.appimage---->uboot.img---

So if U-boot is part of the boot flow then boot is working fine. So could you check the log difference with and without U-Boot w.r.t cma regions?

Regards,

Keerthy
