Hello,

"MbedOS Error Info: pinmap not found for peripheral" when using SPI communication between two boards

Hello, I’m trying to make two boards (NUCLEO-F746ZG and NUCLEO-F103RB) to communicate with each other using SPI. However, my slave code does not seem to work on neither of the boards. I checked the master code using a logic analyzer and it is working as it should, so something’s wrong with the slave code. In the case below, F1 is master and F7 is slave. This is the error message I get: ++ MbedOS Error Info ++ Error Status: 0x80010130 Code: 304 Module: 1 Error Message: pinmap not found for …

It is now working

So this code worked when the boards were connected directly, but didn’t work when you used shields?

BR, Jan
