Forum Post: RE: BIOS SPI using GPIO as CS

Seems you aren't getting much attention from Texas Instruments in this forum. Maybe try posting in the other forum "Embedded Software->TI-RTOS".

Assuming the GPIO instance and CS flags are setup, eg:
 chanParams.hGpio = gpio0;
 dataparam.flags = Spi_GPIO_CS | Spi_CSHOLD;
the ***.c code should eventually call:
  Gpio_setPinVal(chanHandle->hGpio,&userPinCmdArg);
Maybe the chanParams.hGpio is not getting copied to chanHandle->hGpio. I think you might have debug this by stepping through ***.c to see if Gpio_setPinVal() gets called.
