Hello.
Has anybody successful experience with eMMC and TinyRex ?

[robertferanec]

What exactly would you need?

[eugene128]

I'm trying to use eMMC as bootable drive, thet connected to SD4 PINs.
I can read device passport (vendor id, disk size, etc).
But I have some troubles, when I'm trying to get access to internal filesystem.
Here is theme on NXP: https://community.nxp.com/thread/531747

Can Linux see the eMMC?

[eugene128]

Neither uBoot not Linux see connected eMMC, it is may be bad driver (on NXP community I've got advice to update software staff, because it a bit outdated) or damaged hadware (eMMC is particylary broken).

Currently I've sent log of initialization process to eMMC manufacturer, maybe they answer, is it software problem or hardware problem.

[robertferanec]

It should work. Be sure, eMMC is correctly connected and has high quality routing.

Ok, thank you for advice.
We'll change eMMC module, maybe it is broken.

[eugene128]

yeah, you are right.
I changed eMMC and it works, thanks
