Hello.
I've updated & rebuilt osmocom and now I can't use osmocon on gta02 anymore
:(
Previously I started it like:
./osmocon -i 13 -m romload -p /dev/ttySAC0 layer1.highram.bin
power-cycle modem and it started to load firmware.
However with recent version firmware is loaded even without power-cycle!
When I use hello_world.highram.bin I got exactly the same output as before.
But when I use layer1.highram.bin I have problems running
osmoload -l /tmp/loader ping
Query timed out.
What went wrong and how do I fix it?
best regards,
Max.

I just realized that it looks like I just unable to power-down modem on shr:
# echo 0> /sys/bus/platform/devices/gta02-pm-gsm.0/power_on
# cat /sys/bus/platform/devices/gta02-pm-gsm.0/power_on

I'm not sure if it's really so and how can I fix this...
Here is the dump I got with compal_dsp_dump.highram.bin payload:

Btw, where can I get documentation which will help to interpret those values properly?
looking forward for your advice,
Max.

False alarm - mistake on my part: not all modem-related services were disabled.
Problem solved, wiki updated.
sorry for all the fuzz,
Max.
