Re: [Paparazzi-devel] Problem with luftboot on Lisa M 2.1

Hi Felix,

so I found out today that my Lisa M 2.0 has broken JTAG connector, so I can't test the fix. Also, the bad JTAG connector might have caused the problem with bootloader in the first place - apparently the connection was bad for a while and today it gave up.

Hi Michal,

I unfortunately don't have a working LisaM 2.0 to test, but I think there might be a problem with using lufboot together with a recent libopencm3 version.
Guessing this is the same problem you described for F4 in https://github.com/paparazzi/paparazzi/pull/1017
Would be great if you could test with https://github.com/paparazzi/luftboot/pull/6, although I actually doubt this will fix the usb proken pipe problem.
@esden, do you know of any changes in libopencm3 here?

@Alonso,
Michal is talking about LisaM (with STM32F1) and not LisaMX (with STM32F4).
You don't necessarily need a blackmagic probe to flash LisaMX,  you can also flash via DFU-util using the onboard ROM bootloader of the F4.

Cheers, Felix

I noted this warning at http://1bitsquared.com/collections/autopilots/products/lisa-mx-autopilot :
 This is the new Lisa/MX autopilot, Version 2.1 Revision 3.
 This version of the board does not support programming over the built in USB port. (DFU bootloader) You will need the Black Magic Probe or compatible JTAG/SWD programmer to be able to use this board.

I don't understand why this is case and maybe this is not your problem if it was working previously.

Hi all,

I recently encountered a problem with uploading code via DFU util to my Lisa M 2.1.

I got the latest code from master, and then followed instructions here: http://wiki.paparazziuav.org/wiki/Luftboot (I have BlackMagicProbe). The output from flashing the bootloader:

Then I want to upload code from Paparazzi center (default Quad Lisa M 2) using USB_DFU (autopilot is in bootloader mode), and every time I get this error:

The same error occurs on one machine with Ubuntu 12.04 and other machine with Ubuntu 14.4. Also before this happened, I noticed that DFU flashing got often interrupted and didn't finish (broken pipe error), so I had to flash the code several times.

Does it mean my autopilot is broken (although I can still upload code with BlackMagicProbe and the actual paparazzi code works)? Plus usb_telemetry on this board works, although it has to be uploaded via BMP.

Thanks for help.
Michal
