Hi All,
I have been working with one of my A13 Olimex boards for 7 weeks or so now flawlessly, and when I turned on my Olinuxino A13 today I see an error message on the console saying;
U-Boot SPL 2013.10-rc2-08400-g8a4621c-dirty (Aug 15 2014 - 18:11:45)
Board: A13-OLinuXino
DRAM: ? ? 0 MiB
### ERROR ### Please RESET the board ###
I tried several uSD card images of various builds, but they all report the same thing. I have several other Olimex A13 boards, and they boot from these cards fine. A reset or power cycle still produces the same result on the effected board.
I find it sort of hard to believe that the SDRAM chips has failed - silicon is not that dodgy.
The 1.5V rail is a nice smooth 1.501V - which is good for those sot-23 regs. VTT is a firm .72v - also amazing for a voltage divider generated VTT reference.
Has anyone seen this sort of thing? Or has their board done this?
Cheers,
Steve
