Hi, I have seen some posts in the forums stating that eMMC is not supported in SDMMC1. However some posts state that some users have actually connected an eMMC with good results, so I am pretty confused. The design guide and TX2/TX2i documentation I have seen is not very clear. Could someone please help clarify the situation? (hopefully some from @nvidia could help).
Looking at the parker TRM (DP07821001p) documentation, I see in the table in section 36.5 that eMMC is listed as supported for SDMMC1 (SDR26,SDR52,DDR52, and HS200 in 4-bitmode). However in a few posts in this forum (how to change SDMMC1 to use as SDIO Interface? for instance), it is very clearly stated this is not the case.
Is the advice not to use it based on an electrical/protocol incompatibility or is this due to lack of software support? Or perhaps due to lack of testing?
For reference I would like to connect an eMMC to both SDMMC1 and SDMMC3 (in a TX2i module).
Thanks for any clarification.
