Hello
I have two boards master(stm32h743) and slave (stm32g0b1).
I am trying to use FDCAN intern bootloader to update stm32g0b1.
I have the upgrade file (bin file) for stm32g0b1 saved inside SD-card that the master board has access to.
Stm32g0b1 starts from system memory after booting. I send erase command and write commands from stm32h743 to stm32g0b1 to erase the flash memory and write the new bin file to stm32g0b1 and then i send go-command to jump to application and thats all works very well as i want.
But, when I receive a new upgrade file on the SD-card and attempt to return stm32g0b1 to system memory, it appears to do so but I'm uncertain if this is occurring correctly, as I do not receive any response from stm32g0b1 when I isend commands, such as the erase command.
Anyone has any tips or anything could help me?
I use boot0 pin low to start always in system memory after booting.
And i use NVIC_SystemReset to resend CPU to systemmemory when Master detect a new bin file inside SD-card.
