AM 3359 SPI Module frequency

Other Parts Discussed in Thread: AM3359

Hi,

Working on SPI Module : SPI 1

1) AM3359 is configured as Master

2) Trying to Communicate with a slave device with frequency 10MHZ

 API McSPIClkConfig is used and required parameters are  passed , But when we use frequency greather than 1MHZ  we are not able to transmit data ( Observation in Debug mode : Waits for transmision buffer to be empty).

Below is parameter passed to API McSPIClkConfig

1) baseAdd,  : 0x481A0000
2) spiInClk,   : 48000000u
3) spiOutClk : 1000000u
4) chNum,    : 1
5) clkMode   :  MCSPI_CLK_MODE_1
 
Note : For your Information : we were able to successfully communicate with slave device for frequency less than 1MHZ, Communication fails when frequency is increased above 1MHZ

Regards,

Bindu
