I´m migrating an (working) SPI driver to MQX.
I had to install the SPI interruption something like this:
_int_install_isr(0x2b, (INT_ISR_FPTR)SPIB_ISR, NULL);
the interruption takes place (vector 0x2b) in my own
ISR I'm accessing to SPI register. I can see that the registers
actually get the correct value but the SPI data never goes out,
I mean I can get the MOSI data signals with an oscilloscope. So
I'm stock rigth now
Could someone suggest me how to proceed?
thanks in advance
