./board-support/prebuilt-images/sysfw.itb
./board-support/u-boot_build/a72/tispl.bin
./board-support/u-boot_build/a72/u-boot.img

steps:

1) set custom board to dfu mode.

2) use command " sudo dfu-util -l "

3). use command " sudo dfu-util -R -a bootloader -D tiboot3.bin "

4） dmesg log：

Hi,

What are the differences w.r.t USB on your custom board? Also do you get any traces after loading the tiboot3.bin on the custom board?
Can you also confirm that the EVM DFU is booting till U-Boot prompt at your end?

What are the differences w.r.t USB on your custom board?

==> custom board, it's USB2.0

Also do you get any traces after loading the tiboot3.bin on the custom board?

==> can not get any log from MAIN uart or MCU uart.

Can you also confirm that the EVM DFU is booting till U-Boot prompt at your end?

==>

EVM board is OK. the EVM board DFU is booting till U-Boot prompt at the end. and i can input some command at the uboot console.

Thanks!

HI, Ti teams:

there is some difference between "TDA4VM EVM board" and our "DV board" after exec command " sudo dfu-util -R -a bootloader -D tiboot3.bin ", the log as below.

Hi,

Can you help us understand where the code is stuck using CCS? Is it out of ROM code and it has started executing the R5 SPL or it is stuck in ROM Code itself on the custom board?

Also can you try the below change in U-Boot dts:

Best Regards,
Keerthy

HI Keerthy:

add "ti, usb2-only;" in dts, the same error occur.

thanks.

Hi,

Can you help to check if we are out of ROM Code or executing in R5 SPL? That will help us understand the issue.

HI, Keerthy

How to check "out of ROM Code or executing in R5 SPL" ? when i load tiboot3.bin, there is no any log show in mcu uart.

thanks!

Hi,

The R5 SPL code starts from 0x41c00000. So any address starting 0x41cxxxxx will mean we are executing from R5 SPL.

Hi, Keerthy

We think the root cause is that the MCU1_0(R5F) is not powered on successfully after the tiboot3.bin was downloaded successfully. But we don't know how to debug this issue. And for now, considering the limitation, our customer ZF can't measure the signal and associated voltage.
