EDIT : OMG, i missed this and just booted fine the generic image . Remains small issues and questions below …
My issues are not big ones BUT they are annoying, let’s start :
→ My SBC was preloaded with CE because it’s a HTPC Kit AND before doing anything to my board, i dumped eMMC content using OOWOW. I keep it safely.
→ My goal was to boot CE from SD and Ubuntu from internal : done ! BUT it has been a long way to make it …
→ OOWOW has a few bugs with my board, for example i have no way to embed it into SPI, just because i find the key combo access handy in this case … anyway that not my point, it is a very helpful tool.
→ I was aware that CE Team gives almost no support for KRescue CE images and i believe that it was what i had preloaded : in first place i wiped eMMC and flashed a custom Ubuntu Jammy built from KHADAS sources using docker : the build configuration and process is fast and reliable and my image does boot and works very well . That was step 1.
→ Step 2 : boot official CE image from SD => never worked. I learned of lot of things about my board during multiple tries of SD boot BUT finally i dumped again eMMC (Ubuntu) and flashed KRescue CE image to it without using my first eMMC dump (preloaded CE) AND here issues begin :
→ blue LED is gone
→ u-boot logo is gone
→ To make it the shortest possible : preloaded CE to internal had everything : u-boot logo + CE logo. Ubuntu has evrything too ! u-boot logo + kernel logo + Ubuntu logo. Krescue CE image lacks u-boot logo AND blue LED is gone in every case now …
… untill i tried again to reset MCU without DCIN out the board BUT simply pressing the reset button shortly to boot the board up again with blue LED back (if i DCIN out, then settings were not saved and blue LED was still down) …
… that is a progress BUT blue LED mode appears to be set to hearbeat when power is off or on !? I can provide some videos if is relevant … i do know how to set it back to stock because i found the command lines over the internet BUT i am unable to enter into u-boot mode, either with Ubuntu or CE : if someone could tell me how to do that it would be really great because even hitting space bar since power is on gives nothing else than booting into the OS …
I apologize for this long introduction, now comes bootable SD with CE : i lately known the ceemmc tool, so i ran it from my KRescue CE image and installed it to a SD card => i now have a bootable CE SD card BUT i have a few questions :
→ is it still Krescue or not on the SD ?! If it is, what is the best way to boot official CE image from SD please ? Even if the word official can also apply to Krescue ones i guess …
→ how can i restore u-boot logo on it ? I found answers about Ubuntu and Android, that is all.
I have no intention to renew eMMC installation of CE from SD. Ubuntu is on it and CE on SD and works pretty very well !
To conclude, i am wondering about the best way to boot CE from SD, did i make it right ? Also if anyone can help me to solve this blue LED issue, i would be very happy with it !
PS : i own several ODROIDs and one ROCK960 AND it has not been that difficult for me to learn how to use them, compared to VIM3L. These three brands (HK, 96boards and KHADAS) are great IMO AND even if my head was about to explode because of the VIM3L, i must say that i do have a small preference for it.
Have a nice day,
Any help will be greatly appreciated,
