help my GPS freez
hi petrutms
i have a NOWADA GPS card N117 V5
the menu is like the 3rd photo in yr 1st post
it has a problem in it:
sadnly it freeze in the booting screen, but some times it works, like 10 times will not work and one time works
but now is dead, just on the booting screen
when i look on the net i found its datasheet but in chine's
i get mange to know every pin what it is
so i remove it and connect it to a computer screen
Note the boot screen ( navigation system)
I think that the system can't complete reading the main frame program from the flash memory
But what I note too that there is a LED blanking at 1 Hz ( the red one in the photo)
Also there was a Calcareous deposits on the PCB, I clean it but with no successes
Now as you say before that you are work in the NOWADA company, can you help me in any way
Sorry for making this post long
Here is also some photo of my board
