Right, using the same GPIOs for two SPI instances and doesn't have uninitializing code in the end of bootloader.

It makes sense that SPI2 is being used in bootlodaer and F/W will not be abled to initialize SPI3 with the same GPIO.

I verified that uninit SPI before jumnping to F/W can fix this issue.

Thank you!

Hi,

Are you using the same GPIO pins for the two SPI instances? Is the SPI peripheral uninitialized/stopped in the bootloader before the jump to the application is made?

Can you provide an example that can be used to reproduce this behavior?

Best regards,
Jørgen
