no boot white led flashing

[mlohdael]

Well I want to stick on debian mainline stable It is really a pity that there is no qualified output from debian as even the so called stable versions are
buggy.

A list:
almost all pine64 can not be installed with the official *.iso installer
rock64 - debian-installer  refuses to boot
rockpro64 - debian-installer has to be on the SD-Card an the installation has to be done on the SD-Card. The installer remains on the SD-Card
pinebookpro with debian -no way but armbian did it.

I believe armbian is the first in line for arm
then Ubuntu
then debian SID & testing
then debian stable

So I have no excuses for the debian stable branch which is not even able to provide a proper and painless installer like amd64/i386_64
It looks like a strategy to keep people off arm cpu's.
Ant this is an ongoing pain in the .. since 2018 since four years...

In fact we are throwing 1/3 of our manhours away for silly and for the pro's simple tasks.
They did not even guess that grub and EFI is not a good relation.

I thought your post was about a non booting RockPro64. I suggested Armbian as a means of testing the board. This is a tinkerers board and the work needs to be put in to get a particular flavour of Linux to boot it. I'm afraid there's nothing else I can help you with other than what I previously suggested. Best if you contact the manufacturer directly.

i am having issues booting a rockpro64 after newly flashed  SDcard and all the LED's come one (even the white, blinking one), but nothing comes out of hdmi. there is a slight chance that i may have accidentally shorted something near the hdmi port and am not realizing that, BUT, i am trying to use armbian 22.11.1 kernel 5.15.80 and having the same 'not booting' issue. i have used this image before, so i KNOW 100% it works. i have updated as much as i could through armbian-config, so maybe it updated some firmware for something (i cant specifically remember) and this is causing my problems? i'm not sure. i'm trying to eliminate the fact that i didnt accidentally short out the port. but, what he said is correct, from what i can tell, that IS indeed an issue about a rockpro64 they're talking about.
