EMMC SDK for esp32

Postby abcdcadb » Wed Sep 06, 2017 12:25 am

I tried to communicate to an external emmc chip using ESP32.

Of course, the library i employed, Sd card gives error.

I read from the notice in SD card code is "Only SD cards (SDSC and SDHC/SDXC) are supported now.
* Support for MMC/eMMC cards will be added later."
I believe that that library has been released for a long time, so is emmc available at the moment?

I have it working. I've submitted a pull request on GitHub, but am waiting for it to be merged to master.

https://github.com/espressif/esp-idf/pull/590

I welcome any feedback about the patches.
