ECS Liva Install

[kbocek]

I have a new ECS Liva and got some help from Toracat getting my PXE setup working with UEFI booting. Thanks Toracat.

However, the installer doesn't recognize the on-board storage (either 32G or 64G). When I go to setup storage, I'm told none present.

The specs here:

Describe "eMMC" memory.

Does anyone have any experience with this hardware?

I found this posting:

Talking about an add_drivers line for an mmc driver. But I'm unclear where I'd do this.

The add_drivers= line is in /etc/dracut.conf but isn't going to help you because that's only present once the install is complete. You could try switching to console 2 using ctrl-alt-F2 and using modprobe to load the driver names that followed that parameter in the other post: add_drivers+=" mmc_core mmc_block sdhci sdhci-pci ". So modprobe mmc_core for example (repeat for the others). See if that allows it to detect the device. Post-install you may need to edit that file _before_ you reboot and possibly regenerate the initramfs with dracut though it may work without.

I would imagine needing to regenerate initramfs since we are talking about access to the boot device here. How else doe the OS get up and running?

It's been years since I've needed to do this whole dance.

So I thought I'd try CentOS 7.1, thinking it would have more up to date drivers. Alas no. Still no local disk at install time.

However during kernel boot I am seeing something like:

mmc0:
Unrecognized EXT_CSD Rev 7
Error -22 while initializing

So this mmc driver *is* being loaded, but it's not recognizing this hardware

I went back to 6.6. No mmc messages from the installer in the ring buffer. I did the process you mentioned and modprobed the four modules before getting to disk setup. Still no disks recognized.

It's kind of looking like this is hardware that the upstream vendor just doesn't support at this time.

Yup, CentOS 6 and 7 are old. I downloaded Fedora 21 and got from the installer:

mmc0: new hs200 card at address 1
mmcblk0: 29.1GiB

The installer identifies the internal storage as "MMC 032GE4"

I'm installing Fedora 21 as I write this.
