We started a few days ago to work with a fastrack supreme device.
After setting the development environment we download the hello-world sample application and it worked ok… later we modified that sample and download to the device. This process fail and after that the device is not working as expected and the behavior is not deterministic.
When it’s powered-on the red led turn-on for a few seconds and then keeps turned off.
Sometimes it at least answer ERROR to most AT commands but other times it’s completely dead. The only command that gives an “OK” answer is the AT itself and the Download command, but when we try to send any firmware using 1K Xmodem via Hyperterminal it says “HEADER ERROR”
At the OpenAT IDE it’s not recogniced at “autodetect”.
Any ideas on how to recover the device?
Thanks in advance
