Re: [Paparazzi-devel] Umarim

[Hector Garcia de Marina]

Hi Marc,

yes, you are right. I was refering Lisa/M instead of Lisa/L, my fault.

The reliability is indeed a good point, but I believed that Lisa/M was older and more tested than Umarim.
About the bootloader, the ST32F103 (which is in Lisa) already has one by default over UART. But already I do not know if Boot0 and Boot1 pins are reachable in Lisa/M.

Cheers,
Héctor.

Hello Hector,

direct comparison to Umarim would probably be Lisa/M. I also have one of these here, but it does not seem to be completely ready and tested (regarding I2C, Bootloader..). So for me, prooven system plus size are points for the "old" architecture...

At the moment Lisa still seems to be a developement platform while many groups need usable systems.

Poor availability of hardware in europe is the other problem...

Cheers

Marc
