Sd_cd


#1

As there appears to be nothing documenting the connection of the SD card for the G400 I dug through the Fez Raptor schematic and see that it connects to PD7 on that board.

Can I assume that this is the pin that is used in the firmware to detect the presence of the SD card?

I currently have it on PB15 (pin 159) as this is the same pin that was used with the old ChipworkX.


#2

On the G400Header PB8 is located on pin3 of the “F” connector. But i guess the firmware does not rely on detecting the presence of a SD card by checking the logic state of a pin.
For the G120 it was recommended to place a resistor of 1Meg from DA3 to ground.


#3

OK. It was a directory failure. I wasn’t running in debug to begin with.

It was still set for SD_SPI but once changed to SD it now works.

Phew… BUT I am still not modding the other 3 until I need them. :slight_smile:
