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

Hi,

With this options you are overwriting the bootloader on lisa/m. When you have 
the bootloader loaded you only need to change the FLASH_MODE to be JTAG and the 
paparazzi system takes care of only loading the firmware in a way so that the 
bootloader is not touched.

So please don't put your options into the wiki.

If you have a working bootloader (luftboot) on your lisa/m 2.0 you can also 
flash the firmware by calling

make AIRCRAFT=<name> FLASH_MODE=JTAG ap.upload

On the command line.

The NO_LUFTBOOT option is only for the cases when you really explicitly don't 
want to use a bootloader, what should be either in the case of old LISA/L that 
does not have USB interface and Lisa/M 1.0 that needs hardware modification to 
make USB work. But again that is taken care of by the board files, so it does 
not need that option in your airframe file either.

Cheers Piotr
