@chris178 im using this image ( r5 512 ) with the mem=4g param i tried the nick A image too, same problem. ( i tried the r4, r1, 512 and 4096 ) i didnt tried a different microsd, im going to buy a new one and make a new test maybe i got a faulty board. (im using npu and a lot of cpu, everything running fine) Srry about my poor english, is not my native language 😅

@tiobily Ram detect and training looks just fine above.... you could interrupt the boot and test memory. what OS image did you use above? I could try it on my device (also 8GB but modded). Did you try different microSD cards? Just tried @Nick A image and u-boot section is very similar. However boot continues with linux kernel at the point your debug stalled.... I can't see much clue as to why you're having that issue from the log above unfortunately... Just tried https://github.com/radxa-build/radxa-a733/releases/download/rsdk-r5/radxa-a733_bullseye_cli_r5.output_512.img.xz on a 8GB moded A7Z and it boot fine and free mem as expected...

Thanks, I ran from sdcard and these options work on Dolamee D5: overlays=cpu-hs emmc emmc-ddr-ph45 led-conf-default

Hi Igor, Thank you for your reply. I build an Image for Mekotronics R58V2, but I leaned today we dont have the R58S2 (yet) our current device is the R58s, with a build provided by Mekotronics and the HW decoding works with QT-Multimedia as playback back-end, This is this build: v26.02 rolling for Mekotronics R58S running Armbian Linux 6.1.84-vendor-rk35xx. This device is not yet supported, at least I could not find it here. I will discuss with Mekotronics to get also at least Standard support from Armbian in future. I do have also Mekototronics R58X and R58HD devices we want to use also in ffuture the have better support level here as well. I could not find any Forums related to Mekotronics devices and seams can not open one or add threads to the Rockchip rk35xx section, there loads of OragePi stuff but I could not see that officially you support any of them, anyway I gave up with them cause they are ...lets say below expectations ;-). Please give me a hint. As Iam new here please excuse if you get sometimes strange question, but Iam working with arm boards already for a while. Using CLI is not an option, we actually install LX-Qt together with the application. Thanks for helping!
