s32G274RDB2 using BSP ATF

[sdx111]

I am using the construction method of BSP35.0 yocto. The fip.bin and fip.s32 generated here are generated by FIp.s32-qSPI, and I want to be generated by FIp.s32-sdcard instead. Where can I make this change?

Hello @sdx111, 

There is no documented way to change the fip.bin/s32 to be the same as the sdcard instead of the qspi. Can you describe more about your problem? What are you traying to solve with this change?

Thanks in advance for the information

I was debugging the bootloader and starting M7 core and A53 core. I needed to download fip.bin of A53 core to Norflash and fip.s32 to EMMC, but startup errors occurred. NOTICE: Reset status: Power-On Reset
NOTICE: BL2: v2.5(release):bsp35.0-2.5-dirty
NOTICE: BL2: Built : 13:21:28, Nov 29 2022
Warning: Instruction at BL33_ENTRYPOINT (0xffaa0000) is 0x54000100, which is not a B or BL!
NOTICE: BL2: Booting BL31

I think that this generated fip.s32 does not correspond to the download to EMMC.

Hello @sdx111,

You can flash the file with the sdcard suffix with no problem or rename it yourself with no issues. If you require an multicore application I can recommend checking AN13750: Enabling Multicore Application.

If you keep having problems please share more details about the complete process you are following, this is: Bootloader configuration, Changes to ATF/u-boot code, building commands, flashing commands and dip switch configuration when booting.

Let me know if this information was useful.

With reference to AN13750, modify the patch shown in the following figure to build bitbake arm-trusted- firmfirmware -C compile and bitbake fsl-image-auto. During boot, the DIP code is Norflash startup, and dual-core startup is shown in the figure below.

I would like to know what other programs in BSP35.0 need to be changed?

Hello @sdx111,

All the steps related to change files are present in the application note I mentioned, it is useful to have previous IVT configuration experience. If this is your first time configuring an IVT image I strongly recommend checking S32G-VNP-RDB2 Software Enablement Guide.

Please be aware that you will need to download the following package AN13750SW - Software for application note AN13750 to be able to complete the application note.

Let me know if this information was useful.

I was able to start both core A and core M, but once executing the bitbake arm-trusted- firmware-c cleansstate command, Cleansstate won't recover, so the IVT setup should be fine. The modified part is refer to 0001-fip-align-and-mmc-init.patch in AN13750SW-Software for application note AN13750. So there should be other changes in BSP35.0.

Hello @sdx111,

Could you elaborate more on how you added the patches to your yocto build? what steps did you follow to add the mentioned modifications?

Are there any log errors when you try to run the bitbake arm-trusted- firmware-c cleansstate command? can you share them with me?

Thanks in advance for the information.
