Few days ago I was tuning the copter through mission planner config/tuning section. So there was no issue with connection, getting or updating parameters at the time. Since then I made a few changes to Erle Brain 3 unit:
- enable ros.services
- install and setup blockly per instructions on GitHub
Having issues launching blocky because of permissions. The only thing I tried to do was "sudo -I" for super user mode to launch blockly (unsuccessfull so far).
Today I tried to continue tuning PID's but when power on and apm is launched, I can connect APM planner via 915MHz 3DR telemetry radios (connected by USB on Elre). However, APM planner is stuck "getting params 1" window. I can arm the copter with RC remote so it seems to work but cannot use planner.
I haven't found this issue so far in this forum. Old ardrupilot forum threads explain this issue and some answers lead to memory corruption or other issue with copter firmware.
Is there some way to figure out what has broken since the listed changes before I have to start over with new install?
