HI,
I am using EVM AM572x with McSPI3 mater mode (Pin multiplexing used with IOSET 4), following are the PinMux Configuration and SPI Mater Mode configuration:
PinMux Configuration:
/*CTRL_MODULE_CORE_CTRL_CORE_PAD_MCASP4_ACLKX Pin mux configured as SPI clock with slew control and receive disabled*/
*(volatile uint32_t *) 0x4A003734 = 0x00080002;
/*CTRL_MODULE_CORE_CTRL_CORE_PAD_MCASP4_FSX Pin mux configured as SPI Data 1 with slew control and receive enabled SPI Data in MISO*/
*(volatile uint32_t *) 0x4A003738 = 0x000C0002;
/*CTRL_MODULE_CORE_CTRL_CORE_PAD_MCASP4_AXR0 Pin mux configured as SPI Data 0 with slew control and receive Dsiabled SPI Data out MOSI*/
*(volatile uint32_t *) 0x4A00373C = 0x00080002;
/*CTRL_MODULE_CORE_CTRL_CORE_PAD_MCASP4_AXR1 Pin mux configured as SPI CS[0] with slew control and receive Dsiabled SPI Chip select*/
*(volatile uint32_t *) 0x4A003740 = 0x00080002;
/* SPI Configurtion */
*(volatile uint32_t *) 0x480B8110 = 0x00000308;
*(volatile uint32_t *) 0x480B8124 = 0x00000201;
*(volatile uint32_t *) 0x480B8128 = 0x00000001;
*(volatile uint32_t *) 0x480B812C = 0x000603C0;
*(volatile uint32_t *) 0x480B8118 = 0xFFFFFFFF;
*(volatile uint32_t *) 0x480B8134 = 0x00000001;
when i triggrer the SPI transfer by writing MCSPI_TXx (0x480B8138) , i am unable to initiate SPi transmit i do not see any clock generating on SPI CLK Pin. Can you suggest where am i going wrong?
