strange communication problem

[lucamemini]

Hi all,
I'm try to upload new code on my RA (not plus) but get this communication error:

avrdude: stk500_getsync(): not in sync: resp=0x64

- COM port is correct (currently COM3) and try this from different PC
- TTL/COM cable working properly (tested with WIFI Attach)
- With "Serial Monitor" try to send to RA "GET /r99" without any result

In the past i'm loaded my custom code without problem....
Any idea?

thx!
Ciao!

Try one of the other boards.
It may be that your board is one of the very early ones without the optiboot.

Ciao Roberto
same error... (different offset)
The main unit is old... uhmm about 3 years (not remember correctly)

but... probably upgrade my board to RA+...

grazie mille
