Hi,
Today I wanted to install
my Lisa/M v2.0, borrowed from my Quadshot Espresso, into a fixedwing
setup. I made an airframe file for it, it is attached to this email.
I checked out v5.0 and
built the firmware. On powering up Lisa/M, it went into bootloader
mode as soon as I had connected both ends of the usb cable. The firmware was uploaded
without problems. Everything worked fine after recycling power, and I
got Telemetry. This is what happened every time I uploaded Quadshot firmware.
I wanted to use another
radio file, so I changed that and built the firmware again. Now, when
I connected the usb cable for the second time, Lisa wouldn’t enter
bootloader mode. Nothing in dmesg indicated that any usb device was
connected. Upload did not find any bootloader.
I rebuilt the code
again, tried with another PC and another cable, checked that
usb delivers voltage to Lisa, no success. Lisa won’t enter
bootloader mode.
Could it be that the bootloader was overwritten? Everything
worked perfectly first time when I had switched from the toytronics branch to v5.0
If I have to get a JTAG adapter to fix this, it seems I need the
serial number of my Lisa/M. Where do I find that?
But I cannot understand what caused this...
Thanks for any help,
Helge.
