DS210j, board ADM22L1 v1.3,
Went dead suddenly, currently only blue led blinks. No sings of life from debug console.
Found that flash chip is damaged - stayed quite hot when touched and i wasn't able to read/erase/write it in external programmer due to overcurrent error.
Appeared that i need new chip (25P32) programmed with rebuilt image. Altough i've managed to extract rd and zimage from syno PAT update, i couldn't find bootloader in none of update files. Is it possible to download or compile stock bootloader image intended for this particular board/CPU? (88F6-BIA2)
Another problem was about finding memory layout. Googled for ds210j bootlogs, found something:
0x003c0000-0x00400000 : "RedBoot"
0x00000000-0x00200000 : "zImage"
0x00200000-0x00380000 : "rd.gz"
0x00380000-0x00390000 : "vendor"
0x00390000-0x003b0000 : "RedBoot Config"
0x003b0000-0x003c0000 : "FIS directory"
which is weird because of redboot placed not at 0x00 flash addr.
When looked at bootlogs of other similiar devices, like ds110j:
0x00000000-0x00080000 : "RedBoot"
0x00080000-0x00280000 : "zImage"
0x00280000-0x003c0000 : "rd.gz"
0x003c0000-0x003d0000 : "vendor"
0x003d0000-0x003f0000 : "RedBoot Config"
0x003f0000-0x00400000 : "FIS directory"
This layout seemed more reasonable to me.
Does anyone can confirm first memory layout, or give a hint how to extract such information?
