Has anyone had success with MicroPython SD card access on the CoreInk? I just installed the firmware that seems to be about 1 week old, but all I get is different error messages when trying to mount the SD card. With slot 1 or 2, I get:
E (8624) sdmmc_common: sdmmc_init_OCR: send_op_cond(1) returned 0x107
With slot 2, I get:
E (8049) spi_master: spi_bus_add_device(373): host not initialized
E (8052) sdmmc_io: sdmmc_io_reset: unexpected return: 0x102
With slot 3, I only get OSError(16,), without additional info.
If anyone has gotten the SD card to work on the CoreInk, which slot and pins do you use? Is there any other initialization necessary?
