pfe mcu master a53 slave

[shiyiheng]

Hello:
The bsp38 version I use now, the 2020 version used by uboot, and the RDB3 development board need to connect one HIF to MCU in our project, which requires MCU to be the master and a53 to be the slave. However, I think the current uboot will load the firmware by default, resulting in the failure of the master-slave boot mode. Is there any way to avoid it?

Hello, @shiyiheng 

Thanks for you reply.

May I know if you are workng with S32G2 or G3? I understand that you are working with BSP38 from A core side, which version PFE MCAL is used from M core side?

Hello, @shiyiheng 

Thanks for your post.

I remembered that the M core master, A core slave is supported,  The PFE slave would be used under u-boot or Linux? May I know what is your specific issues met during the configuration?

hello

Before the release of BSP39, uboot does not support slave mode. May I ask how to realize the use of MCU as master and A53 as slvae when BSP version is upgraded? The pfe network can be used in uboot without affecting the MCU initialization master. What solution is adopted before BSP39 or any good suggestions?

thank you
