So fluid is still not flashing the image, but I noticed the following
messages on the console
after my latest attempt:
The error message:
rxerr: port ch=0x00, rxs=0x0000000c
shows up in dmesg after I send the command:
echo "AT at POFF" >/dev/ttySAC0
Looking back through dmesg, this seems to be a pretty consistent
error message:
modem wakeup interrupt <----result of " echo 1 >/
sys/devices/platform/neo1973-pm-gsm.0/power_on"
rxerr: port ch=0x88, rxs=0x00000004 <---result of "echo "AT at POFF" >/
dev/ttySAC0"
rxerr: port ch=0x00, rxs=0x0000000c
rxerr: port ch=0x14, rxs=0x00000004
rxerr: port ch=0x61, rxs=0x00000004
rxerr: port ch=0x12, rxs=0x00000004
This happens consistently as a result of the following command sequence:
root at om-gta02:/usr/sbin# echo 0 >/sys/devices/platform/neo1973-pm-gsm.
0/power_on
root at om-gta02:/usr/sbin# echo 1 >/sys/devices/platform/neo1973-pm-gsm.
0/power_on
root at om-gta02:/usr/sbin# s3c24xx-gpio b7=0
root at om-gta02:/usr/sbin# echo "AT at POFF" >/dev/ttySAC0
root at om-gta02:/usr/sbin#
This is referenced in this bug report:
http://docs.openmoko.org/trac/ticket/2180
So it looks like my attempt to apply the fix for this bug may be
getting stomped on by the bug itself :)
