Questions Regarding X-NUCLEO-67W61M1 interface testing with STM32F7

[JamesLee]

Dear ST Support Team,

I attempted to test the interfacing of X-NUCLEO-67W61M1 using 32F746GDISCOVERY, but unfortunately, it did not work as expected. In order to resolve this issue, I have several questions:

I am trying to test X-NUCLEO-67W61M1 using STM32F7 instead of the sample products list(H7S3L8, H563ZI,N657X0-Q ...). From what I understand, the listed boards are simply examples for which you provide ready-made code samples, but the X-NUCLEO-67W61M1 should be interfaceable with STM32F7 as well. Is that correct?

I implemented an NCP Loader for 32F746GDISCOVERY based on the sample code for NUCLEO-H7S3L8 you provided . I also modified the batch file in an attempt to retrieve the chip info from X-NUCLEO-67W61M1, but the operation failed. Below are the batch file I used and the error message I encountered:

Additionally, I'm confused about the UART RX/TX pin configuration of X-NUCLEO-67W61M. I connected STLINK_RX to pin 2 (D1/TX) and STLINK_TX to pin 1 (D1/RX) of CN9, but no data was received. When I reversed the connection, a stream of unexpected data appeared. This seems to contradict the schematic. Could you please confirm whether this is the expected behavior?

I am eager to resolve this issue and would greatly appreciate your help. If there are any points I might have overlooked, please let me know.

Best regards,
