But I'm really not sure what you're doing, I'm not even sure if you put u-boot in. At least you didn't mention it.
I wrote:
I wrote your image to sdcard using balena ...
... and as I did not know, whether your "of=/dev/$(DEVICE)" is the disk device or the partition device (i.e. sdf or sdf1) I tried both.
None of them works.
So having written the image to sdcard with balena, the only command where I could confuse "of=/dev/$(DEVICE)" is the u-boot transfer.
- So first try (before my quoted post):
sd-card initialized with balena writing your image on it
Then writing u-boot to /dev/sdf1
Insert the sd-card into rockpi and power it on. Nothing happens
- second try (before my quoted post):
sd-card initialized with balena writing your image on it
Then writing u-boot to /dev/sdf
Insert the sd-card into rockpi and power it on. Nothing happens
- Third try (yesterday):
wipeout of sdcard with dd
Writing your image to sdcard with balena
Writing u-boot to /dev/sdf
Connect rockpi to beamer and power it on.
I saw some boot messages where I thought, I had read the word "Fedora" - but it was to fast. Then the obvious systemd messages and after appearance of gui I had to realize, that the rockpi did boot another system from emmc.
On other rockpi with emmc - when I insert a sd-card, rockpi boots from sdcard and not from emmc.
Anyway - I removed the emmc and powered the rockpi on again - having the sdcard with your image inserted. Some boot messages appeared, but after reset of graphic system, nothing more. No systemd messages, no gui, nothing.
Sadly the boot messages disappeared to fast, so I can't say, what really happened. Hope that will be better with serial console ...
And I don't understand the fact, that this rockpi has no output connected to computer monitor (whatever linux I insert to boot from), but does have correct output connected to a beamer. Other rockpi has correct output connected to computer monitor.
The only difference is, that the computer monitor has no hdmi-input, so I use a hdmi to dvi converter.
I checked edid-data from both situations - they appear correct to my limited knowledge.
