Hi guys!
I have a broken DS218 NAS, it worked for 3+ years and then it randomly died. It's not really releated to this topic, but I think you guys might know more about this CPU than me :)
The UART says the following and then the CPU halts.

I verified the SPI flash contents, even reflashed the bootloader using the original synology loader but it fails.
I also verified the data being read out using a logic analyser and everything seems to work just fine.
Also tried flashing different bootloaders into the SPI flash (BPi UBoot) but nothing really works.
The CTRL+Q on-chip-recovery terminal works, however it does not want to execute any code for some reason.
I read somewhere that the FSBL might be encrypted, is it possible that the keys inside the CPU (efuse or OTP memory ?) somehow got corrupted and so now everything is just invalid?
Does somebody has any info of what this "verify fsbl fail" means?
Cheers,
Bence.
