RT1050 custom board.
May program success to access FlexSPI port A1 or port B1 Flash in Individual mode. (IP command)
But how to configure port A1 + B1 in parallel mode (IP command) ?
I try to setup IPCR1 bit 31, failed always.
Check out the mculcd SDK examples, it uses FlexIO in a parallel configuration, although I'm not sure how useful that will be for FlexSPI...
