RT1060: is it possible to use a GPIO as CS pin for SPI in Slave mode?

[rj_eng_01]

Hello, 

I recently designed a custom board that will connect to another board using SPI eDMA but there was a small issue in the design where I swapped two pins on the board (Frustrating!). I swapped LPSPI_03 PCS0 pin ( GPIO_AD_B0_03 [G11]) with a GPIO pin ( GPIO_AD_B1_04 [L12]), and before I go through the trouble of ordering new boards which is a costly endeavor. I wanted to know if there were any good alternatives that could potentially fix this hardware issue in software. 

I initially thought that it would be a simple task going through the SPI library and seeing if there was a pin declaration that I could just swap with my pin, but it seems that there is a bit more to it. Is there a way that this could be done? 

I also thought that FLEXIO could be a potential option but saw that the pins are not on the same instance and some don't support FLEXIO.

Hello @rj_eng_01,

Unfortunately, a workaround for this issue does not exist, this because the module of SPI depends on a specific CS since have certain connections via hardware.
 

Sorry for the inconvenience this may cause.
