I have found info that this message might pop-up when accessing an uninitialized on-disk u-boot environment happens. And it is the fact that my box loads also from the HDDs during the start.by jean - uBoot
There had to be something corrupted in the bootloader because when I put the testing HDD out, started the box, then put HDD in the another slot and booted again, u-boot started to push bad CRC message so saveenv and reset had it done in the final.by jean - uBoot
Once I will finish this torture, I wil try to describe what I did, now I proceeded further somehow getting to the stage when DS is up, accessible, installed but blue LED still flashing and NAS unable to reset (by little hole in the back) or restart (only HDD goes down and then serial console shows reboot failed - system halted) the system by the ordinary way.

I finally succeeded in loading kernel, but boot ends up by incorrect login although I use correct credentials... :-/ Bootlog is attached.by jean - uBoot
I wonder if ATAGS is not required because FDT (DTB) missing or corrupted? I tried to use fdt addr but when running fdt header after, putty got stuck.by jean - uBoot

I tried almost all FWs available to no luck. Same error always... :-/ I used bootm. So should I use bootz instead? And mem addresses I put it in are correct? Bootz returns "Bad Linux ARM zImage magic! error"...by jean - uBoot
Thank You for the explanation and willingness. Would You pls ensure me lookin into my printenv that loading zImage to the 0x2000000 and rd.bin to 0x2880000 is correct procedure?by jean - uBoot
It is on the Synology ftp site https://archive.synology.com/download/, I only don't remember exactly what version was last functioning, guessing it was 6.1.5. BTW is there possibility that my "no ATAGS support" error is somehow related to the fact the loader is not provided with either any at all or correct MAC and S/N of my NAS? I also wonder what if I try to put older version ofby jean - uBoot

Synology assistant and hard factory reset are not working. Thanksby jean - uBoot
