S32G bootloader use Trace32 script cannot start A53_0

nevc — Thu, 09 Jun 2022 01:50:19 GMT

I'm using Platform_Software_Integration_S32G2XX_2021_09 version, when I use trace32 script to debug the bootloader, it is able to start cm7 app, but cannot start uboot; but when I use IVT version bootloader, and flash IVT bootloader, cm7 app, uboot on the QSPI flash, power on the board, cm7 app and uboot all worked well.

When use Trace32 script to debug, why uboot can't work well?

Hello nevc,

You have to change the script to a one that does not use the ivt, I guess trace has one of this if not you have to create one.

Thank you very much for your reply.

The script I'm using is as follow:

ENDDO

when I'm using this script download Bootloader.elf on board, debug it step by step, after copy uboot.bin and cm7_app.bin form QSPI flash to Ran, pull A53 out of reset but uboot can not run as well, pull cm7_1 core out of reset, cm7_app run well.

Use the same Bootloader.bin and make it with IVT information, then flash Bootloader_IVT.bin、uboot.bin、 cm7_app.bin on QSPI flash, reset the board, boot uboot and cm7_app run well.

Want to know why use .cmm script debug the same project online, it does not work?
