NACK using STM32G071 or F072 UART System Bootloader from STM32G071

Initially a comment on the How to program an STM32 with another STM32 using an embedded bootloader Knowledge Base article.

Moved to the forum for better visibility & discussion.


STM32G071 --> STM32F072STM32G071 --> STM32F072 Hello Mr Montanari,

Thanks a lot for your article.

I carried out the following test with Host: STM32G071KBT6 and devices: STM32G071KBT6 or STM32F072RBT6. In both cases, I encounter a problem when reading the Flash (0x4002200); the response is NACK (STM32G071) or ACK followed by NACK (STM32F072). Could you indicate potential solutions to resolve this problem? Thank you in advance.
