Did you connect the E-pad(pin29) to Ground?
thank you YYCA -
after we removed tghe soldered device we found out that there was a manufacturing failure and so the EPAD = pin 29 was not soldered !
it is interesting to add that the device XTAL was oscilating properly and the device even replied with the K-CHIRP foloowing SE0 command !
thank you VERY much !
You are welcome. Congratulations!
