Bootloader flash - myths and reality.

Posted by Marco Paggot on March 3, 2015 at 7:45am

Hi,

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.

Any ideas?

    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:

    Init ArduCopter V3.2.1 (36b405fb)

    Free RAM: 1999
    FW Ver: 120

    load_all took 34736us
    PANIC: AP_Baro_MS5611 took more than 1000ms to initialize

    Apparently there's something wrong with baro or the circuit that powers it up.
