Is it real to flash bootloader on glitched APM2.6 with inbuilt USB connection?
DFU mode - functional,
PPM encoder - flashed (was empty when I last checked),
Firmware flashes via MP - OK, but doesn't boot.
My guess is bootloader got busted.
I guess, I have to answer myself.
Due to accidental +5v applied to SPI port, 3.3v power regulator been blown up.
I've just found alternative one and soldiered it on 3.3v pin of i2c bus connector.
Everything works perfect.
At meantime I also flashed new version of ppm encoder (which was not present at all 0_o). At lease Flip reads said so.
Well it was not totally necessary, but it did no harm either.
Ok, I see that there's active community here.
Well, the story goes on. I've connected with Putty directly to COM12 port and terminal gave me this:
Apparently there's something wrong with baro or the circuit that powers it up.
