Hi I am developing a library, I am getting a SPI.h compile error. The error: Only occurs on this library AND only for Uno R4 minima. All the other SPI libraries(one last week) I have written compile fine for Uno R4 Minima. compile Error message is Compiling library "SPI" /home/gll/.arduino15…

SPI.h compile error, error: 'g_ioport_ctrl' was not declared in this scope

Could you please post the code that generates this error using code tags?
I have used SPI in both the MINIMA and WIFI without issue.
