Mks-Sbase
The MKS-SBASE has a level shifter in the SPI circuit and therefore the EXP1 connector cannot be used. However adding an onboard jumper allows the J7 header to be used instead. Solder a jumper between pin 4 on U11 to pin 2 on the J7 header.
Firmware and Config
Firmware for the MKS-SBASE is LPC1768
In your .hal file, you will need to configure the Remora chip_type to “LPC”
loadrt remora_lpc chip_type=LPC
