Supported eMMC version in MCUXpresso

Hi, all

I'm trying to boot from eMMC, and also make the image using MCUXpresso.

I have a query about it, which version can be supported in tool & driver?

I found the lastest version for eMMC(v5.1B) which is released last year.

It's working with new version properly as well?

Hi @ljs1004,

Thank you for contacting NXP Support!

Please note that the i.MX93 is not an MCU, but rather an applications processor.

According to the datasheet, the supported eMMC standard is eMMC 5.1. I am not fully certain about the specific differences between versions 5.1 and 5.1b, but to ensure compatibility and avoid unexpected issues, I recommend using devices that comply strictly with eMMC 5.1.

Best regards,
Chavira

Thank you for reply.

I'm having some trouble which is not booting up properly.

Thus I'd like to know that there is any sequence to check eMMC version in MCUXpresso.

Especially there is change in v5.1B :

EXT_CSD[192] : 0x8 -> 0x9
