"I have one question :
I don't quite understand the interactions between the px4 autopilot project and the Pixhawk one. When I look at the pixHawk project, I see that the hardware used is different to the px4 autopilot and is not using an RTOS. I…"

"Nice ! Is it running the nuttx rtos based software ?"

"I think that's what all other potential buyers inluding me are waiting for ..."

"Thanks for your answer,

I also very much appreciate the whole system architecture. I think I'll wait to see something flying for real before I get it. The architecture looks very promissing but the nuttx RTOS seems to be very new and not that well…"

"This question is probably a bit out of place but can someone tell me what is going on with the code side of the px4 project ?"

"So, here are the frequencies the UAV DevBoard will run at:7.5 MHz : fast RC16 MHz : crystal30 MHz : fast RC + 4X PLL60 MHz : fast RC + 8X PLL120 MHz : fast RC + 16X PLL

I don't underdand why these frequencies are the only ones acceptable. I see…"

"Thanks for your answers !
 
But then, why not selling the UDB with a bootloader already installed ?

"I'm trying to load the code with PicKit2. I use pickit2 as standalone with the pickit2 associated software. I connect the board with the triangle on the pickit2 facing the dash on the UDB4, power it with external 5 volt power source. After selecting…"

"Can someone tell me wether picKit2 would be ok to program it ?"

"Hi everyone,

Can you do some debugging on the UDB using the pickit 2 ?"

"Fantastic ! Getting one step closer !"

"Leaves me speechless ...
Congrats !"
