The uC starts the communication sequence but show the mensage
"Unable to communicate. (transmit/receive)"
Does anyone know how I can fix it?
:-\
What have you tried and what were the results?
Thanks Andy!
I am using two USB to USART connector. One is connected to the Fashtool another in docklight.
-> Set the Crystal Frequancy at 16MHz,
-> Put the ISP0 to ground;
-> Power on;
-> Load the .hex file and try to Start. (all other conf are default)

Andy, I sent the esacademy form according to the instructions on the flashtool form, but I have no option to share the fmd file. I'm waiting for the instructions. Tks
You should be able to attach to your forum post. Don't zip it. However I have just sent you an email - please reply to that. Andy
Your log file shows that Flash Magic sends a block of data (as you mentioned in your post) and then nothing is received back from the device after that. Hence the transmit/receive error.
There is not much Flash Magic can do if there is no response. Try increasing the timeouts in the advanced options. If that doesn't help then I would suspect something in your communication path (do you have a transceiver? RS422?) or the microcontroller is being reset somehow. Perhaps an intermittent power supply.
