PC Engines APU2 BIOS options

amps2volts

Stupid question. I just got a apu2c4 and believe its running older BIOS version. When it boots says coreboot build 20170228 SeaBIOS (version rel 1.10.0.1).
On the PC Engines (how to page) lists 4 BIOS versions as current now? What version do I run?

apu2_v4.0.7.rom.zip
apu2_v4.5.5.rom.tar.gz
apu2_160311.zip
apu2_160307.zip

From the dates seems like v4.0.7 dated newest 2/28/2017 maybe I do have latest since my version matches the date 20170228 ? And why is v4.5.5 dated older 2/24/2017 ? The way PC Engines does BIOS versions is very confusing. And can't find explanation anywhere.

4.0.7 is latest. 4.5.5 is experimental.

4.0.7 is what I'm running.

Alright got it. And coreboot build version that shown during boot goes by build date and not actual version? So coreboot build 20170228 is version v4.0.7 ?

fredfox_uk

I think so…... Been a while since I watched the boot sequence :) but 4.0.7 is dated 20170228 - if that makes sense ! :)

Thanks for help once got installed pfSense said BIOS v4.0.7 on front page.

fredfox_uk

You're welcome :)

Anyone already any experience with the apu2_v4.6.0.rom.tar.gz with is the new coreboot mainstream version?

What process have you guys used to update the apu2c4 ?

I have a serial to USB adapter on the way I assume it's needed I purchased mine with pfsesne pre loaded the bios is 03/07/2016

You could look here http://forum.ipfire.org/viewtopic.php?t=16032 and you'll need the serial to usb adapter and a null modem cable

Good luck

Well this esteemed user says that pfSense has a package that will do the update too.
https://forum.pfsense.org/index.php?topic=136548.msg750664#msg750664
Just in case you missed that post.

So to do this on pfSense I did the following:
From pfSense WebGUI>Diagnostics>Command Prompt

pkg install -y flashrom

mkdir /apu

Then uploaded the uncompressed rom from my laptop to pfSense

Upload File
apu2_v4.6.0.rom

File will end up in /tmp
This will be deleted on reboot so copy to /apu with Command Prompt

cp /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.

FranciscoFranco

Upon bootup on the bench I go to #8 Shell
From there i check to ensure rom is there.
ls /apu

Then 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.

Enabling flash write... OK.
Found Winbond flash chip "W25Q64.V" (8192 kB, SPI) mapped at physical address 0x000                     00000ff800000.
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?

FranciscoFranco

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.

So it appears the name has different spelling. So I took a gamble and forced it.

Seemed to work fine. Help my breath and rebooted:

BIOS version v4.6.0
2032 MB DRAM

SeaBIOS (version rel-1.10.2.1)

Press F10 key now for boot menu

Booting from Hard Disk...

1  pfSense
2  pfSense

F6 PXE
Boot:  1

Consoles: serial port

Looking good. Back online with it now.

@Jailer:

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.

Thanks 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.

Cheers Qinn

@FranciscoFranco:

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 ;)
