Hello all,

 

I am a new user to Gumstix and I have the following problem:

 

Equipment: Overo Fire COM, Chestnut43, LG touch screen, SD 8G,

 

Attached COM to Chestnut, with or without SD, attached LG screen, and power cable.

 

No boot sign appears, red and blue led on chestnut continues on, screen light is on (screen turned to bright) and nothing else happens.

 

I tried to follow instructions in forums, reinstall SD (format with Windows CE), and nothing helps.

Even connection via serial is not working (Kermit, Hyper Terminal or Putty).

 

I’m afraid that I miss some fundamental step.

 

Please advice

 

 

Thanks,

Ariel Weinstock
