      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.

      Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

        @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.
            IMG_0496.JPG IMG_0495.JPG IMG_0494.JPG IMG_0493.JPG

            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.

                    Hopefully this one cuts it. First up, clonezilla:

                    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/1471989

                      But 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?

                        @Uncle-Frank Perhaps it’s not such a big issue after all:

                        • My understanding is the RPMB partition is effectively doing what regular desktops do with EEPROM chips - store OEM license keys
                        • AFAIK Windows does not treat this partition as mountable - it doesn’t show in disk manager (the tablet is out of battery at the moment - will post a pic in a bit)
                        • Theoretically if I could clone p1-p5 as listed above then I should be all set
                        • The license or OEM data in the rpmb can remain as is across each unit

                        So in theory, if we apply Nell’s patch to ignore the rpmb area, we should be able to make this work.

                        The question is what needs to be done to the initd to get it to work?

                          @AsGF2MX Would it be acceptable for FOG to provide a Windows PE environment via PXE Boot with an installation script for Windows 8.1 for this device to make it automated?

                          It’s not traditional I know… but what are you going to do? Go pay for a product when FOG can still help you?

                          I mean… If we created a PXE Option that booted windows PE and just went through a Windows Recovery process, would that be acceptable? It would apply applications and restore settings. I suppose with the FOG Client installed on this device, it’d rename it and join it to the domain later too.

                          Is this viable - at-least until we can get better support for your device?

                                Tom pointed me to a discussion here in the forum about a similar issue some time ago. Search for emmc and you’ll find a thread with a user called d4rk3.

                                Could you please enter a FOG debug session and run the following two commands fdisk -l /dev/mmcblk0 and lsblk /dev/mmcblk0
                                I guess the output of fdisk will be empty. Would be interesting to see what you get from lsblk.

                                As far as I can see clonezilla is showing the partitions with fdisk because it is debian based and debian has added the mentioned patch. See here: https://launchpad.net/debian/+source/linux/3.16.7-ckt9-1 (“eMMC: Don’t initialize partitions on RPMB flagged areas”) I downloaded the debian patchset to look through it and it’s got this patch by Nell Hardcastle (https://dev-nell.com/rpmb-emmc-errors-under-linux.html) in it!

                                @Tom-Elliott Would you mind adding this patch to 4.2? I know you’ve done this for d4rk3 some months ago. Didn’t seam to work for him but I wonder why.

                                  @Uncle-Frank I’m rebuilding now, should be done in about 5 minutes. I added the patch. Just a note, I don’t have a simple way to patch this to work around the block. I had to manually code the patch, which would only be good on a one-to-one patch of the version as things change quite often between kernel updates.

                                  I, again, won’t know if this works until somebody tests/confirms it as well. Hopefully your suggestion here will be viable and help ALL users out with eMMC SSD Cards.

                                    Patched mmc drivers and built kernels are now up and running. You can update by choosing the latest kernels in the kernel update list, or by simply rerunning installer if you’re running development versions.

                                    Thank you,

                                      I’ll give the kernel a whirl tomorrow at work and report back if anything’s changed.

                                        @Uncle-Frank @Tom-Elliott the output of fdisk -l /dev/mmc* or lsblk with the same returns no such file or directory. This is even with the newest kernel.

                                        Since we don’t even see the MMC device, I’ve been going through a few things over the weekend and I might have found something. The eMMC device is operating in ACPI mode per windows and also per Clonezilla. The HS200 device sits at ACPI\80860f41:0001 Comparing the dmesg outputs between clonezilla and fog, I don’t see the above address anywhere in the FOG dmesg output.

                                        After a little poking around for Kernel issues with Baytrail, it turns out there is an extra kernel option needed to make Baytrail work in a sane manner: CONFIG_PINCTRL_BAYTRAIL=“y”

                                        When I looked at the kernel options with your name in git, the above is not configured or even defined. Would you be able to set the above to “y” and recompile the 32-bit kernel once more please? If it is already there then something is a miss.

                                        This seems to very specific to Baytrail which the Venue is using. I do not have any info on Cherrytrail. If this works then the patch sets applied earlier should also take out the rpmb issue so it should theoretically be the one kernel that just works!

                                          Looking through the links I find they are talking about SD cards not eMMC drives. Maybe I got this wrong?

                                          I wish I had one of those devices here to poke around with it myself to make it work.

                                          Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                                            @Uncle-Frank Not all of them but the SD and eMMC controllers are on die so being unable to address them correctly could explain why it doesn’t show. I would think that at least mmc0 would show in FOG but it doesn’t - there is no dev node for the micro sd card - the SD card shown as SDA1 is actually a USB SD card reader.
