TMS320F28379D: Need help to get SPI B working on TMS320F28379D launchpad

Tool/software:

Hi all,

I want to get SPI B working on the TMS320F28379D launchpad to interact with a LDC1101 eddy current sensor. I want the launchpad to be the master and the ldc 1101 the slave. I am using the SysConfig tool to configure SPI and GPIOs.

When I do so and call SPI_transmitByte(base, WRITE_CMD+START_CONFIG_REGISTER), this function does not succeed. 

However, when I run the same SPI code (configured via SysConfig) using SPI A configured on the launchpad (instead of SPI B), it works without any issues.

I have used the following pins for SPI B:

PICO GPIO63

POCI GPIO64

CLK GPIO65

Is there some configuration that I need to enable/set to get SPI B working on the launchpad? Any help much appreciated!

Thanks
