Hi There

i made my own PCB based on Netduino plus

I am using RS232 serial communication to upload firmware

I run SAM -BA 2.12 .

I use a jumper to erase and then reset

It worked sometimes but after only many attempts

I checked PLLRC filter and all in order

Could someone please advise me what should I look for?

Many thanks in advance

Hi Nissim, What board is selected? SAM7X512-EK? What kind of RS-232 port are you using? Direct or via USB adapter? What brand of adapter? Chris

Thanks for your reply. I am using Sam7x512 ek. My board has max232 . I am using a pc with serial db9 socket. Some reason. Out of 10 tried it might connect to Sam ba 2.12 once. I am keen to figure out why.
