Hi @Nick A, the armbian in afiftyp board just see 2GB to, at least it was this way in 2024 when he sent me his boot log. My board is very similar to afiftyp board, except of a number near the QC sticker, that looks like a version number. afiftyp number is 2336 and the mine is 2333. The amout of memory chips is identical to (8 chips), but tha labels is a litle different, but I cant found the label meaning. I use your image since very old one, so I don't think it is about u-boot update, but I could try an older one. About Secure Boot, A patch that you give me solved it and it isn't a problem any more (thanks again for it). @afiftyp, if I'm wrong and you already solve your rom amount in armbian, please let us know and if you could, explain us what you did to solve it, thanks.

Hi Ryzer, hi Igor, I was out of town for a while, but recently I could try out the new Armbian release v25.8.1, which incorporates the changes made by Ryzer. I chose kernel version 6.15 and did get an HDMI output on a Dell 21,5" monitor. So I managed to configure the pcduino2 for its purpose and I am using it again after many years. Excellent! Thank you so much for all your efforts! Great to be back as an Armbian user. Just as a side note: I was first trying with my Dell UltraSharp 34" monitor and there the HDMI output still does not work. I does work with the old Armbian 5.38 version for pcduino2 from the archives and also with Raspberry Pi 3 using a recent version of Raspberry Pi OS. Anyway, this is just for information. I do not think it is worth investigating this issue.

Something like git clone https://github.com/armbian/build.git -b main cd build git remote add -f imx8mp-build https://github.com/OLIMEX/imx8mp-build.git git remote update git fetch origin git fetch imx8mp-build git checkout main git rebase imx8mp-build/bookworm # fix conflict vi VERSION git add VERSION git rebase --continue # fix conflict vi .github/dependabot.yml git add .github/dependabot.yml git rebase --continue git log

They certainly did fork armbian, apparently at tag v24.11.1 AKA dd379da888f7d114f9f954d94a7ebcf261d179e5 $ git merge-base dd379da888f7d114f9f954d94a7ebcf261d179e5 main 017549347bb8c278a067d1be14c2f1b3538690c2 Add the Olimex repo as a remote and then rebase the latest armbian/build HEAD to their HEAD.
