Hi, I have a LPC2294 board. When I try to init SPI program crashes. OS is RL-ARM and spi_init function executes "SSPCR0 = 0x00C7;" instruction in simulator then it gives the folloving error: "Data Abort: Thumb Instruction at 00000C7EH, Memory Access at E005C000H"
void spi_init (void) { /* Initialize and enable the SSP Interface module. */ U32 i; /* SSEL is GPIO, output set to high. */ IODIR0 |= 1<<20; // OK IOSET0 = 1<<20; // OK /* SCK1, MISO1, MOSI1 are SSP pins. */ PINSEL1 = (PINSEL1 & ~0x000003FC) | 0x000000A8; /* Enable SPI in Master Mode, CPOL=1, CPHA=1 (Clock low-active). */ SSPCR0 = 0x00C7; //!!!!!CRASHES HERE SSPCR1 = 0x0002; SSPCPSR = 0xFE; /* Send SPI Command with card not selected at 400 KBit. */ for (i = 0; i < 16; i++) { spi_send (0xFF); } /* Enable SSP auto select. */ PINSEL1 |= 0x00000200; }
