Unfortunately I start the osmocon processes like this: ( /usr/local/bin/osmocon -s /tmp/osmocom_l2 -l /tmp/osmocom_loader -p /dev/ttyS0 -m c123xor /usr/local/bin/layer1.compalram.bin ) < /dev/null > /dev/null 2>&1 & I could now start all of them in a screen session, where I could see the latest output afterwards. Since it is so much output coming, I don't want to keep it in a logfile. If it helps I could do that, too. In any case I have to wait for the next crash... But when I look at the cpu time used, it seems that the osmocon process is still doing something. I could now test any command you tell me on the mobile application. Today in the evening, when I am home I will restart it (with osmocon in screen). > Some people wire-up one of the serial port control line to the enable > line of a power supply they use to power the phone so they can do full > power off/on, but it requires external hw. Ok, you mean using an unused serial line and raising the control line to control a relais, which virtually presses the power button then? With such a solution I would have another problem. Often, when I switch off the phone, I can't switch it back on. Even without the connected serial line, I can't switch it on booting the original firmware. I have to remove the power (which is a altered batteriepack, hooked on a powersupply with ~4 Volts [like the battery had before]), wait 30 seconds and put it back on. Then I can start it again. Is that a known problem, or looks it like to be a problem of my altered powersupply? Thanks Tim
