SPI bootloader (board to board) - not getting any acknowledgement

[AnoopYadav]

Hello ,

I am using STM32H750B(host) device and STM32H743ZI as target board . I am using spi2 from host side and spi1 for target board, after putting my target board in boot mode i am running application from my host device , i can able to see on logic analyzer that synchonization byte(0x5A) is being send followed by dummy byte(0x00).

But i am not able to get any ACK or NACK.

I am using the spi bootloader from here https://github.com/glegrain/STM32-SPI-Bootloader-host

I have kept these settings for SPI.

Do you have the same issue when using STM32CubeProgrammer?
