Benchmark of an embeded computer with ARM CPU using solar power...

calao solaire

- solar cells :
iSun (ICP Global Technologies, 290 mA @ 7.6 V.
- USB converter :
made in China USB-CLA ; input 12-24 V dc / output 5.5 V dc, 700 mA.
- computer :
Calao Systems USB-A9260, CPU ARM Atmel AT91SAM9260, système linux UclibC 2.6.20.
- position :
48°53’ Nord 2°25 Est
- date :

When the computer is pluged to USB-solar cells and at the same time to internet via ethernet port, the system starts to boot , as the green LED on the mother board can say, but break down fater before 2 seconds...

Since I can use this solar system to power my mobile or my PDA - it works - I may be optimistic, the power chain seems not stable enougth, what should I do ?
