lora-e5-dev: SD card

[jdavid]

I ordered this card reader https://circuitstate.com/tutorials/interfacing-catalex-micro-sd-card-module-with-arduino/ to work with the LoRa E5 board. But didn't get it to work yet.

$ BOARD=lora-e5-dev make -C tests/driver_sdcard_spi all flash term

I have tried with the Arduino IDE and Arduino UNO following https://circuitstate.com/tutorials/interfacing-catalex-micro-sd-card-module-with-arduino/ and it worked.

For the record:

• Could not test Arduino's example with the Arduino Zero because cannot flash anymore. I think it's because with RIOT I use system's openocd 0.11 while the Arduino IDE uses openocd 0.10

• Could not test RIOT's tests/driver_sdcard_spi program with Arduino UNO because doesn't have enough program memory

• Saw that in lora-e5-dev button D0 and SPI SCK use the same PB13 pin, so I disabled the button D0 with the jumper, but it did not change anything.

[jdavid]

The error we have is that CMD0 works byt CMD59 times out.
If I unplug any cable then CMD0 doesn't work.
Except for MOSI, which doesn't make any difference (CMD0 ok CMD59 ko).
Tried to plug the MOSI cable to D9 with no change.
