Other Parts Discussed in Thread: AM3359
Hi!
I am trying to run SPI0 outputs on AM3359 ICE V1 board by modifying ethercat_slave example code:
I am initialising it using
McSPIInit(MCSPI_INSTANCE_0, 48, 1 ,MCSPI_SINGLE_CH, MCSPI_CHANNEL_0);
and tying to run it using
McSPICycle(MCSPI_INSTANCE_0, &charbuff[0], 4, MCSPI_CHANNEL_0);
Inside pinmux function pins are initialised as
{ 0x0950 , 0 , AM335X_PIN_OUTPUT | AM335X_PIN_INPUT }, // spi0_sclk
{ 0x0954 , 0 , AM335X_PIN_OUTPUT }, // spi0_DO
{ 0x0958 , 0 , AM335X_PIN_INPUT_PULLUP }, // spi0_DI
{ 0x095C , 0 , AM335X_PIN_OUTPUT }, // spi0_cs0
However I am not getting any outputs: CLK is constantly high and CS and D0 are low.
Edit:
Could it be that it is going in conflict with SPI flash on which is connected to the same line.
Could you tell me what I am doing wrong.
Thank you!
