Dell Venue 8 Pro imaging/eMMC

As far as I can see there is no MMC support compiled into the current FOG kernel. I guess you are the first one asking
See here: http://sourceforge.net/p/freeghost/code/HEAD/tree/trunk/kernel/TomElliott.config.64
... # CONFIG_MMC is not set ...I guess Tom will happily add MMC support and compile a new kernel in the next few days…
-
@Uncle-Frank Or 10 minutes :). I’m currently rebuilding the kernels and they should be complete in about 4 minutes.
-
Kernels are updated. Just rerun your installer if you’re on development and you should have kernels with mmc support baked in. The config files are already updated for this.
-
We probably need to tune scripts as well to make devicenames like /dev/mmcblkX work but lets see if the new kernel is bringing up those first.
-
You’re probably correct, though We have made great strides to make the “block” device as generic as possible. If they’re running on Trunk/Dev, things should be okay.
-
@Tom-Elliott Are you meaning to say that I should do a git pull first to get the new kernels? If so, I do have a test FOG environment and will do so on that. Just in case I need to break something :).
Please advise.
-
since you’re running a relatively recent version of trunk, running the installer you already have should automatically download the latest kernel as it runs
-
I just updated the kernel in place and it seems that just like 4.1.6 kernel that the fdisk -l produces 15 devices named /dev/ram0 to dev/ram15 at 124MiB each.
I am going to run the install script just in case there are some other changes involved.
-
Yeah, I did not update 4.1.6. I Updated 4.2.0. This will not work on kernel 4.1.6.
-
Well this thread made a whole lot of progress in a short period of time… Job well done. I’m leaving it to you guys to figure out the rest lol.

@Tom-Elliott I am on the latest git and Kernel 4.2.0 right now and it’s still showing the odd /dev/ram0-15. I ran through dmesg and I see the following points of interest:
multiple occureneces of Not using MMCONFIG
Then:
ACPI PNP0A08:00: _OSC: OSC failed (AE_ERROR); disabling ASPM
ACPI PNP0A08:00 fail to add MMCONFIG information, can’t access extended PCI configuration space under this bridge.There is a Winbond W83L51xD SD/MMC card interface driver showing a bit further down but that looks like the MicroSD card on the side.
Sidebar - if I want to boot an ISO via iPXE, how would I do so? I’m currently at home and I just realized I haven’t got a single USB drive on me. I do however have ISOs on my ESXi box and also I got FOG. Not trying to go off topic but trying to see if Ubuntu iso or even clonezilla will identify the storage device.

@AsGF2MX said:
fail to add MMCONFIG information
MMCONFIG is not MMC! AFAIK this error is unrelated. See here: http://lwn.net/Articles/263288/
Don’t you see anything about mmcblk in dmesg? Like here: https://gist.github.com/thomasdziedzic/01482f33aba5971845b3
Booting ISO from iPXE is possible. Search the forums for “ISO” and you should find a lot of information about it.
-
@Uncle-Frank Did not spot the missing C - I thought it was MMC CONFIG. I was searching for mmc in dmesg and that’s all it showed. Searched for blk as well and got nothing. Do you know what kernel generated that particular output? I don’t have any custom settings in my FOG setup except that I am forcing the boot of the 32-bit kernel and not the 64-bit one via the UI so I have to ask if any specific switches or anything is needed anywhere? As usual, I have secure boot disabled as well.
On the ISOs, I did find the some info but I couldn’t make sense of where to put those lines in within the UI. On the other hand I did grab an SD card reader and I have a clean SD card so I will try to make a bootable drive or two in a few hours and hopefully get something back.

That did help me to get an active partition but it seems Ubuntu is a non-starter as I couldn’t even boot it. I was then able to just unzip the ISO contents of Clonezilla alternate stable (current off site) and boot.
It is on kernel 3.16.0-4-amd64 and there is an MMC block device shown.
There is indeed and mmcblk0 being shown in clonezilla but I can’t get the 4.2 kernels from yesterday to do the same. I tried to find the header file for the kernel build options but I couldn’t find it from the sourceforge portal.
How can I help troubleshoot this further?
-
@Tom-Elliott might have updated the kernel - but sometimes changes need made in the inits too, wonder if he did that?
-
Are you referring to init scripts within the initrd or something else? Since there are no modules here I am not sure how to even get the mmc recognized in dmesg.
-
Please post all of the output of this, so we can clearly see it (proper camera positioning and focus).
fdisk -l | more -
Hopefully this one cuts it. First up, clonezilla:
FOG:
The 8GB device is the SD card I’m using to boot clonezilla.

Others seam to have issues with Samsung eMMC disks as well. See here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1422338
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1471989But notice the different models, MDGAGC in the first and MCGAFB in the second bug report. Not sure if those were ever solved.
From what I can see in the first screenshots your model is a MBG4GC which I sadly cannot find much about when searching for those error messages. Not sure if this is related: https://dev-nell.com/rpmb-emmc-errors-under-linux.html
I am sorry but I guess this won’t be an easy catch. You/we might need to get in contact with kernel developers. Not 100% sure yet.
Could you please try other live linux systems to see if one of them goes without the errors?
