Hi,
I am having problems on receving data from SIN from DSPI_2 and cannot move further with my application.
I send data normally on SOUT (MOSI) and can see on the osciloscope when comes on the SIN pin, the processor sets the flag "RFDF=1" and "RXCTR = 1" but the RX registers are always 0.
I have tried different configuration approaches and the result is always the same:
The status registers shows that there is new data available on the SPI
DSPI2SR:
RXCTR = 1
RFDF = 1
but on the receiving register it comes always 0 -> DSPI2POPR = 0.
DSPI2POPR = 0
DSPI2RXFR0 = 0
DSPI2RXFR1 = 0
DSPI2RXFR2 = 0
DSPI2RXFR3 = 0
I have checked the physical connections of the SIN pin and is all working fine.
I also have set the SIN PIN to normal GPIO (as input) and managed to read the input normally.
Considering that it could have been a problem on the DSPI_2 module of that specific CHIP, I have changed the processor with a new one and the behavior is exaclty the same.
Has anyone already faced a similar problems ?
Thanks in advance.
