BBB - 5.10.41-bone42 kernel - eMMC not detected on recent Seeed Studio manfactured BBB boards

General Discussion
1

On a 2017 BBB with kernel 5.10.41-bone42, the eMMC appears, and works correctly with the 5.10.41 kernel:

S10004 3.56 GiB
date:09/2016
manfid:0x000070
size:7471104

On a newer BBB (Seeed studio manufactured model), the eMMC is not recognised (although the beaglebone boots from SD card without problems):

~# uname -r ; dmesg | rg '(mmc1|481d800)'
5.10.41-bone42

With the 4.19.191-bone67 kernel, the eMMC works fine, and I can read out the eMMC info from the Seeed Studio board:

It’s also worth pointing out that the Seeed beaglebone black eMMC user capacity is slightly smaller (3616 MiB vs. 3648 MiB) than the other BBB boards I’ve seen, so if anyone has hardcoded partition sizes in scripts etc. these may trip them up…

Yeap, that’s why you lost eMMC…

I’m working on this isssue…

uboot_overlay_options:[uboot_overlay_addr7=/lib/firmware/BB-I2C2-RTC-DS1338.dtbo]

Drop the ‘/lib/firmware/’ part, that way it can pull in the “kernel” specific overlays…

Hi Robert,

Thanks for the response, but the eMMC is not detected even when the SPI-enable overlays aren’t loaded - (see the “With the SPI overlays disabled:” section further down in the previous post). If the same SD card is moved to an older BBB, then the eMMC is detected - so it appears to be a combination of the newer Kingston eMMC (which is on the Seeed BBB), and the 5.10.41-bone42 kernel.

Cheers,

Tim.

If there’s nothing immediately obvious on this, then please let me know and I’ll try and work out when the regression occurred (since 4.19.1xx kernels do detect the eMMC on Seeed BBB, and the 5.10.41 kernel does detect the eMMC on older BBB).

8

This is the issue, i’m working on it… Essentially due to a change in the pinctrl struct, overlays built externally to the kernel are not compatibly with device tree’s built inside the kernel… The change occurred in either 5.8/5.9…

Regards,

OK, thanks.

The problem I had been focussing on was the failure to detect the eMMC on the Seeed BBB. I think this was due to an older MLO (or possibly some other component of the boot process) having been written to the eMMC on the Seeed studio beaglebone, and getting read during the SD card boot sequence.

After booting into the 4.19.x kernel (from sd card), and erasing the eMMC on the Seeed studio beaglebone, and then switching back to the 5.10.41 kernel (still booted from the sd card) was then able to detect the eMMC.

(n.b. this was with the SPI and other overlays disabled).

10

I think I’m seeing similar behavior in switching from BBB to Seed BBG when trying to flash our image via SD card.

Would you mind giving some more detail (how to) into : After booting into the 4.19.x kernel (from sd card), and erasing the eMMC on the Seeed studio beaglebone, and then switching back to the 5.10.41 kernel (still booted from the sd card) was then able to detect the eMMC. so that I can try as well?

11

can you post your logs of those 2 devices, please add:

sudo /opt/scripts/tools/version.sh

for the details bits…

Regards,

12

I will get information you requested when I can (the BBG is not physically with me at present).

In the meantime, uname -a gives Linux beaglebone 4.19.94-ti-r42 #1buster SMP PREEMPT Tue Mar 31 19:38:29 UTC 2020 armv7l GNU/Linux.

I don’t see way to attach log files so will insert.

Oh my, 3.8.13 and a 2015.01 build of u-boot!!!

So… I don’t want to break or corrupt your current data on that device. What do you want that device to do going forward? With something that old, anything i recommend would be to really start over with a fresh flash/install…

Edit:

[    2.315004] mmc1: unrecognised EXT_CSD revision 8
[    2.319937] mmc1: error -22 whilst initialising MMC card

you build is missing these two patches…

3.8.13-bone68b –

This was fixed on: Jun 15, 2016:

and released as 3.8.13-bone80,

Thanks Robert,

We were planning on updating our image later this year - just not now and not in the midst of all these supply interruptions.

We have been successfully flashing boards shipped with beaglebone 5.2.20-bone12 so was surprised that older boards shipping with beaglebone 4.19.94-ti-r42 won’t flash, the difference being that these ‘non-flashable’ boards are from Seeed (I am not making any inference to issues their side).

I will look into patches you mention and may also try flash the seeed board to 5.2.20 and then downgrade to our version (I know this may not make sense, but will buy me time) and see if this works - I’d imaging if issue is related to some difference in hardware though that this won’t help.

I am also very keen to chat to any consultants/contractors to assist with all things Beaglebone.

Thanks again for your continued assistance - we exchanged emails more than once several years back!

Hi @Colin_Bester ,

It’s not about what linux image shipped with the board, it’s about the version of the eMMC modules installed on the PCB.

So the issue is availability of 4GB eMMC modules. Throughout BeagleBone’s manufacturing era we utilized a bunch of supplies from Micron to Kingston… Initially everything was eMMC 4.3 based, but as fab process’s matured, most eMMC 4.3 production went EOL and was switched over to eMMC 5.1…

So today, everything is eMMC 5.1, unless you scrape together some random EOL eMMC 4.3 modules from some wholesale inventory website…

Now to the kernel, right before June 15, 2016 i got a board from Seeed that was the first board to ‘ever’ use these new fancy eMMC 5.1 modules… Committed the patch, and never really thought about it.

Now years later, right on cue about once a month we get an email from users who has the same old…

[    2.315004] mmc1: unrecognised EXT_CSD revision 8
[    2.319937] mmc1: error -22 whilst initialising MMC card

Kinda weird… as it’s now 2022, dealing with an issue that was fixed way back in 2016…

The issue is known, the fix is in git, the issue use to be really easy to fix…

But every year, Linux get’s more and more updates changes… We are now to the point, that old “3.8.x” kernel is now longer build-able on an up to date Linux system (Debian 11.x, Ubuntu 21.04) without even more patches… So if you want to rebuild it yourself, fire up a VM and install an old version of Debian/Ubuntu to help you cross build 3.8.x…

Here is that old tree… Commits · RobertCNelson/bb-kernel · GitHub if your host is using gcc-10 for HOSTCC, there is patch to force it to use gcc-9 for HOSTCC… if your system is gcc-11… yeah no… support has ended…

We even had a user who wanted to add a new usb WiFi dongle to 3.8.x a month ago… Yeah…no…

If your still trying to flash a 3.8.x based image to the eMMC, in 2022 it’s really eol, un-supported/etc…

After all that, if you still need 3.8.x and you can’t patch the kernel… There is another option… Why are you using the eMMC? At this point microSD’s are cheap and overkill on size, just use a microSD and ignore the eMMC…

Regards,

Thanks @RobertCNelson, I was considering using the SD card for now but was worried about reliability as user has no access to SD slot (which is a good thing) and I have no experience on reliability especially in a noisy emc environment and a higher frequency vibrations.

17

If I manage to get the kernel built and seeing as only mmc.c has changed, is there a file (module, library etc) that I can simply copy across to working device with my old version and simply create new SD card for flashing? This would be so much faster than creating new (still old 3.8.x) image and then patching and installing for our setup.

I would think this would be possible (how many times has this been said in ignorance) but I am not sure which file/module etc I would need to copy across.

18

It’s not an external module, the patch touches something “built-in” mmc… You’ll need to swap the “vmlinuz-*” file along with every module it uses…
