Re: [Paparazzi-devel] Lisa/M 2.0 and Aspirin 2.1 available in the Quadshot store

Hello,

I have a lisa M V2.0 that i wanted to flash using floss jtag. I found that the following needs to be added to the airframe configuration file:

<configure name="FLASH_MODE" values="JTAG"/>

<configure name="NO_LUFTBOOT" value="1"/>

I suppose I can add this to the lisa m v2.0 page?

Regards

Loïc

Hey guys,

Sorry for the delayed answer. I was quasi offline the last two weeks.

I just added basic support for luftboot to the dev branch. If you set your 

airframe to use lisal/m 2.0 as it's board the targets will be generating 

firmware that is relocated to 0x8002000 and will use gareths' dfu flashing 

script by default.

After you flashed a payload once you will need to short the ADC2 pin to ground 

to force the bootloader to stay in bootloader mode. Then you can reflash the 

firmware again.

This should not be necessary in the future when we have added a usb stack stub 

to the paparazzi firmware that allows switching to the bootloader using 

software. An example how this could be done is in the luftboot repository. 

(cdcacm example)

Also if you already flashed your lisa/m 2.0 with a firmware using JTAG (and 

overwrote the bootloader) you can restore the bootloader by checking out 

luftboot repository (https://github.com/paparazzi/luftboot) and running:

make clean && make flash DEV_SERIAL="LM2-ser"

in the src directory, where "ser" stands for the serial number of your Lisa/M. 

So for example if you have lisa/m with the serial number 020 this would be:

make clean && make flash DEV_SERIAL="LM2-020"

You still can use FLOSS jtag or Black Magic probe when using the bootloader. It 

"should" not overwrite the bootloader when using the lisa/m 2.0 board. But you 

have to change the FLASH_MODE to JTAG. Look into conf/boards/lisa_m_2.0.makefile

I hope this helps.

Cheers Esden
