PC Engines APU2 BIOS options
-
So to do this on pfSense I did the following:
From pfSense WebGUI>Diagnostics>Command Promptpkg install -y flashrom
mkdir /apu
Then uploaded the uncompressed rom from my laptop to pfSense
Upload File
apu2_v4.6.0.romFile will end up in /tmp
This will be deleted on reboot so copy to /apu with Command Promptcp /tmp/apu2_v4.6.0.rom /apu/apu2_v4.6.0.rom
Then i disconnect APU2 from my utility room and carry to a serial console machine for the actual flash.
-
Upon bootup on the bench I go to #8 Shell
From there i check to ensure rom is there.
ls /apuThen i run the command needed to flash:
[2.3.4-RELEASE][root@pfSense.localdomain]/root: flashrom --programmer internal -w /apu/apu2_v4.6.0.rom flashrom v0.9.9-r1955 on FreeBSD 10.3-RELEASE-p19 (amd64) flashrom is free software, get the source code at https://flashrom.org Calibrating delay loop... delay loop is unreliable, trying to continue OK. coreboot table found at 0x77fae000.

This coreboot image (PC Engines:PC Engines apu2) does not appear to be correct for the detected mainboard (PC Engines:PCEngines apu3). Aborting. You can override this with -p internal:boardmismatch=force.Notice this failed? This was done on an APU3 by accident. Glad they have checks!!

Couldn't you just do this over SSH? And why the update? Is there something not working for you that a BIOS flash will fix?

Well it did not go as planned. I rearranged cases so my pfSense is red and APU2 now and I still had to force the update.

I could have done it over the webGUI maybe. I figured best to do without traffic.
I have a APU1 with the realteks and I want to bring it up to date. So I am doing all of them.
Why does anybody use betas? Somebody has to be the guinea pig.

updated mine today to:
Vendor: coreboot
Version: v4.0.11
Release Date: 07/24/2017Thanks for the advice up and running fine so far

Thanks for this!! Can anyone tell me why you choose v4.6.0 instead of the 4.0.x version. I am on the apu2_v4.0.7.rom version and could use some guidance.

I have a APU1 with the realteks and I want to bring it up to date.
Well that one's easy: they dropped ongoing support for it and haven't issued anything beyond a couple of betas in 2014. Since neither of those betas became the production version in the past 3 years there's presumably something wrong with them.

I chose 4.6.0 because I like living on the edge. This was just a learning experiment so I figured these Swiss people seem to have their act together and trusted them with a beta. It is their only product so I think they know whats going on.

I use my APU1 for GPIO and FreeBSD. I modified the case for it by adding terminal block on top to breakout the GPIO's.
We all know the problems with Realtek network chips but I have found that using only re0 it is a good box for embedded tasks.
Not very worthy as a router. It does make a nice dedicated Wireless Access Point with all those expansion options.I would like to buy any cheap APU1's out there. Drop me a PM if you have one to sell….

Thanks for you reply and the conformation, btw see below ;)

I did notice that they did infact change the device name that it shows as from 'PCEngines apu2' to 'PC Engines apu2' in a earlier rom.
The ROM notes have all the changes well documented.
Why they couldn't handle a device name change without force is unknown to me.
I was reluctant to force it as I have throw out many self fried electronic goodies. Living on the edge. -
In the PC Engines forum someone has "stuck beacon" errors with 4.6 and moved over to the 4.0.11 version, which seems stable for him. I don't have a WiFi module installed on the APU2 board, so maybe 4.6 could be stable.
Yet, the https://www.coreboot.org/Special:RecentChanges suggest there is sill some work on the APU2 and the 4.6 version is of april 2017
( https://coreboot.org/releases/coreboot-4.6-relnotes.txt ).For now I won't upgrade from the 4.0.7 version, as there seems no reason to.
-
I certainly do NOT recommend the 4.6.0 version. Been testing it for 2 days and got 6 inexplicable kernel panics. Never seen one before with 4.0.7.

First, big thanks for the reply Dok!!
It seems that the releases v4.0.x, that are based on the PC Engines fork of coreboot, are the only ones that are stable and it is better to steer clear from the coreboot mainstream version v4.5.x and v4.6.x. Btw have you tried the v4.0.11 or higher versions?
Just a suggestion to report them to https://github.com/pcengines/coreboot/issues
Or to contact this guy https://github.com/pietrushnic who is the maintainer piotr.krol@3mdeb.com -

Been running for ~36 hours by now, no crash. It has broken serial console output though at the beginning of the boot, affecting the pfSense boot menu. Does not happen with 4.0.7.

After a short discussion with PC Engines support, I did a force update on my APU2C4 from 4.0.7 to 4.0.11. In the for what it's worth category, I am not experiencing the serial console problem. Your mileage may vary.

Firmware 4.6.0 has been up since I flashed it on mine.

From the reply of FranciscoFranco « Reply #13 on: September 29, 2017, 04:49:00 pm » the force seems necessary, because they have changed 'PCEngines' to 'PC Engines' in smbios tables and welcome string (see changelog confirms https://github.com/pcengines/coreboot/blob/coreboot-4.0.x/CHANGELOG.md in version v4.0.8 - 2017-03-31). so it seems there is a check on this string before it updates.

Your using the nano version for the APU2C4, just out of curiosity, why? My APU2C4 is equipped with a mSATA SSD and I use the full install.
