|
|
666: detected neocon failure at run 666: restarted neocon; urjtag failed
|
||
|
|
this cycle; back to normal at 667
|
||
|
|
684: checked LEDs again (first time since ~500) and found that standby
|
||
|
|
may be failing. stopping test at 685 (around 02:50) for
|
||
|
|
investigation.
|

|
|

|
Downloaded the standby bitstream:
|
||
|
|
|
||
|
|
wget https://raw.github.com/milkymist/scripts/master/scripts/reflash_m1.sh
|
||
|
|
chmod 755 reflash_m1.sh
|
||
|
|
|
||
|
|
./reflash_m1.sh --read-flash
|
||
|
|
|
||
|
|
Found two corruptions in the standby bitstream:
|
||
|
|
|
||
|
|
diff -u <(hexdump -C standby.fpg) <(hexdump -C /home/root/.qi/milkymist/read-flash/2011...)

CRC-checked the partitions:
|
||
|
|
|
||
|
|
git clone git://github.com/milkymist/milkymist
|
||
|
|
cd milkymist/tools/
|

gcc -Wall -I. -o flterm flterm.c

|
||
|
|
./flterm --port /dev/ttyUSB0 --kernel boot.4e53273.bin
|
||
|
|
|
||
|
|
only standby.fpg failed the CRC check
|
||
|
|

Reflashed the standby bitstream:
