CCS/CC3220MODA: Pin Conflict with GSPI and SDCARD_CLK

Tool/software: Code Composer Studio

Hi,

I was trying to interface SD card on SDIO mode on my custom board which is using CC3220MODA, but when I'm trying to configure the pins on the Sys config, there's a pin conflict between the SD_CLK and SPI_MOSI.

There's only one SPI_MOSI pin on the board but two pins for the SD_CLK. SysConfig is not allowing me to add that pin.

Kindly help.

Akshit,

Do you have the SPI_MOSI Configured in SYSConfig?

Vincent,

My project requires the use of NWP. To use the NWP SPI has to be enabled. In SYSCONFIG, I'm unable to change the pin for the SD_CLK.

Regards.

Akshit,

What version of the SDK are you using? I remember something like this being fixed in the latest one.

Hi Vincent,

I'm using sdk version - simplelink_cc32xx_sdk_2_40_01_01.

Can you confirm this change because this issue is costing me extra development time?
