Re: [Paparazzi-devel] Luftboot new version

[Gerard Toonstra]

Well.. not getting anywhere with the tests for now, I decided to attempt flashing the bootloader, so I don't
have to use the bootloader wire anymore on ADC2.

I'm getting errors. Could be an indication there's some more stuff going wrong.

- First tried to flash through paparazzi as follows.
- I've got the black magic probe connected with the black JTAG plus the serial cable.
- I've modified the config to flash luftboot by configuring JTAG etc.:

    <configure name="FLASH_MODE" value="JTAG"/>
    <configure name="NO_LUFTBOOT" value="1"/>
    <configure name="BMP_PORT" value="/dev/ttyACM0"/> 

Result:

make[1]: Leaving directory `/work/paparazzi/sw/airborne'
cd sw/airborne; make PAPARAZZI_SRC=/work/paparazzi PAPARAZZI_HOME=/work/paparazzi TARGET=ap upload
make[1]: Entering directory `/work/paparazzi/sw/airborne'

Then I figured... let's try by using the make flash commands from luftboot itself. 
- Downloaded luftboot as per the link here
- Figured out to set PATH to the "bin" in the /opt/paparazzi/bin directory
- Downloaded latest libopencm3, set LIBOPENCM3 to correct directory.
- Spotted that the .a file was created in /lib, but not in stm32/f1. Copied to that dir instead
- Ran make again, this time it worked. Then tried to flash using the BMP_PORT="/dev/ttyACM0" again. result:


address@hidden:/work/luftboot/src$ make flash DEV_SERIAL="LM2-152" BMP_PORT="/dev/ttyACM0"

Am I doing something horribly wrong here?  Wrong libopencm3 version?  Hardware issues?

Hi guys!
I've just tested the new version of Luftboot on the LisaM v2 and it works. There is now an USB cable detection implemented, so you can boot up the Luftboot bootloader without an bootloader connector, just plug the USB and turn on the power. It also switches to the app after the upload.
You can download either the binary file from here
https://github.com/softsr/luftboot/downloads
or the complete source code from my Luftboot forked repo here
https://github.com/softsr/luftboot
If there is any questions, I'm always ready to help.

Sergey
