Are eMMC 4.0 and 5.0 compatible? [Copy link]

My main chip only supports mmc4.0 protocol, but the eMMC chip itself is 5.0. Can it be read in this way?

Is it so sad... The previous version's main chip supported 4.3, and it had no problem reading 5.0. I thought eMMC would also be backward compatible, but I didn't expect that this version's main chip would become 4.0 and it wouldn't work. Details Published on 2018-12-8 16:46
