I use the spi master to read the data from the SPI slave FRAM mb85rs512t by the free rtos SDK non-blocking transfer. only one slave device was connected to the SPI interface.
it contains the read command and some dummy data in a transfer. as the data sheet, the CS line should keep low during the whole operation and was set to automatic mode. and the spi was set to single burst and 8 bit as the burst length.so basically the interrupt works well . However the read data is always 0.
But when I change it to the block mode , and set the CS manual mode. or i use the loop back test to see the data, both of them work well.
So could anyone show me how to configure the CS pin automatic configuration ? or any other advice. was blocked here for several days.
