support for 2nd SD card in PiCore ?
« on: September 29, 2019, 02:15:42 PM »
I have just found info on connecting a 2nd SD card on a Pi through the use of SDIO on a SPI bus.
 ( https://www.raspberrypi.org/forums/viewtopic.php?t=176931 )
The hardware side seems quite simple and with a few wires and a module of less than a buck/quid/euro I should be able to add a volume for my data.
I like to have it separate from the boot media as I replace the boot SD quite often during experiments.
Sure USB media and USB SD card readers do exist, but I want to keep it small, energy efficient and probably all on a Pi-Zero.

Who has any advise or experience on this matter from a piCore perspective ?
Is it supported ? Or can we get it to work using the modules we have ?
I am investigating the software side while the SD card module is in transit.

Regards M-H

There should not be anything extra needed for this, just set the overlay and wire it up.

Thanks Paul, That is a good prospect for this HW expansion.
Still waiting for the delivery, so I can't tell yet if it works.
