Cyclone V eMMC bare metal example

[Hamathon]

Hi, I am able to run the SD/MMC example from the FPGA Bare-metal Developer Center with an SD card. Now,  I'd like to do the same with an eMMC.

My questions are:

1. Are eMMC supported by the HWLIB? The SD/MMC driver specifically says MMC are not supported. Is it possible using the NAND HWLIB?

2. I just want to check if there is an example for eMMC cards? I am using a Cyclone V SX SOM with a built-in eMMC.

Any advice to help get a working example up and running would be appreciated. Thanks.

Hi,

Thanks for contacting Intel/Altera forums. Apologies for the delay in getting back.

Per your question 

1. Are eMMC supported by the HWLIB? The SD/MMC driver specifically says MMC are not supported. Is it possible using the NAND HWLIB?

Per the documentation (https://www.rocketboards.org/foswiki/Documentation/HWLib) , eMMC is not listed under supported category. I don't think using NAND HWLIB as replacement to do EMMC would work though but let me confirm this with our guys here.

2. I just want to check if there is an example for eMMC cards? I am using a Cyclone V SX SOM with a built-in eMMC.

Unfortunately I didn't find any eMMC examples in our database, but I saw there some mentioned on programming eMMC on Arria10

Hi,

May I know whether you have further question related to the case , otherwise I would like to transition the case to community support.

Thanks
