Dear Forum,
I am in the process of migrating away from pfSense to Opnsense and have run into a minor issue that I have been unable to resolve. So far I have spent a few days and trawled the forums to no avail so I thought I would post to see if anyone can help.
I am using the following hardware:
CPU: Intel(R) Atom(TM) x5-Z8350 CPU @ 1.44GHz (1440.00-MHz K8-class CPU)
4GB RAM
Intel Bay Trail/Braswell eMMC 4.5/4.5.1 Controller with 60GB MMC/SD
Opnsense Release: 19.7[11.2-RELEASE-p14-HBSD]
I have had this up and running on the latest pfSense release 2.4.4-p3 outwith the nagging UART issue that initially prevented the system from booting (solved with unsetting hint.uart.1.at).
I then wanted to move to Opnsense - for the usual reasons but have run into another issue with the MMC/SD not being recognized. I have so far been able to install to an external USB drive which has at least got me off pfSense but I'd really like to get the MMC working. I know it was working on the pfSense release.
I am guessing that this may be because there is some issue with FreeBSD 11.x and that 12.x solves the issue, this being the primary difference between Opnsense 19 and pfSense 2.4.4 but having spent a long time looking at various threads both here and on freebsd.org etc it does seen to suggest that eMMC support should be there.
I have run a boot -v with the following settings in /boot/loader.conf.local:
hw.mmc.debug=2
boot_verbose=1
and attach the boot log. I can see if recognizes the card OK:
mmc0: card: MMCHC S0J38Y 1.0 SN 0816F9A4 MFG 10/2018 by 19 0x004e
but the subsequent log entries suggest that it's not attaching in the end:

I cant seem to get any further forward.. I would really appreciate any help.

Since this was my first post.. I am wondering if I posted this in the right forum?

In principle yes, I guess....
Maybe sumefink comparable to this here:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228340

We talked about it here in German: https://forum.opnsense.org/index.php?topic=13396.0
The gist is that eMMC driver has an incompatibility with older MMC drivers so we had to not bring eMMC support to OPNsense yet. I am unsure what that means for OPNsense 20.1 and up that will supposedly use HardenedBSD 12.1, but I can say that all tests on version 11 so far concluded the same outcome: it is not compatible.
Cheers,
Franco

OK - that's fair enough. TBH I am getting pretty good results from my usb hdd so I am not too bothered.
Thanks for the clarification.

Hi Franco
Regarding the issue that is being discussed in this thread, unfortunately we are in a same predicament. We dont have the option of an HDD, or USB, so we have to find a way to install OPNSense on the eMMC. Is there any patch available which we can apply to build a custom image which will be able to detect the eMMC and install on it.
As per this bug report, we too are using a Denverton (C3558) to be specific
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228340
Thanks and Regards

From what I can tell 12.1 OS code base in 20.7 (to be released tomorrow, RC out already) will have the corresponding eMMC support that was previously missing from OPNsense.
Cheers,
Franco
