Dear Paul, Sorry for late replying as I am continuously trying to resolve SD card issue from many days. For testing purpose, what I did is, I connected Simple SPI instead of RSPI. When the below function is going to execute : //////// power_on(); /* Initialize RSPI */ for (n=0; n 10; n++) { xchg_spi(0xFF);/* Send 80 dummy clocks */ ------interrupt occurs only at first 0xff. } ty = 0; ///////////// The interrupt occurs at only first 0xff and then no interrupt occurs. What could be the reason behind this???
