  Thank you for your response Gordon.

  I will change my board.

  Hello Gordon, thank you for your response.

  I think this problem is not about Serialx, I tried your code.

  setInterval("LED.toggle",500)
  //device failed here
  

  this command hangs too. device doesn't response after this command and led is not flashing.

  One more issue;
  If I type an undefined function or variable, it also hangs like this :

  gogogo
  Uncaught ReferenceError: "gogogo" is not defined
  Execution Interrupted
  //device failed here
  

  board doesn't response after this command too.

  here is some output that works well and hangs at the end.

  Hello,

  When I try to setup a serial port this board hangs with espruino. I have two boards which has the same problem.

  I have used this commands

  Serial1.setup(9600,{rx:B7,tx:B6});
  Serial2.setup(9600,{rx:B7,tx:B6});
  Serial3.setup(9600);
  Serial2.setup(9600);
  etc...

  all those commands hangs the board, board doesn't response any more. I have tried those binaries

  espruino_1v80_stm32vldiscovery.bin
  espruino_1v91_stm32vldiscovery.bin
  espruino_1v92_stm32vldiscovery.bin
  espruino_1v93_stm32vldiscovery.bin

  Am I doing some thing wrong?

  I want to shoot my self, it was only about the LVP Fuse on pic. I have disabled the LVP Fuse and now it works great with only a 0.1uf ceramic capacitor.

  Hello,

  I'm sorry to activate this thread again.

  After my last post, suddenly it worked with a 0.1uf ceramic capacitor. Then I had a break on this project for 2-3 monts.

  Now, I have created an other circuit as the same of last working one. But getting the same error. Now in my test results pic allways flooding CL-LF (Char 10 and Char 13).

  But when I put the circut 30 cm away from my notebook, it doesn't flood 10 and 13 char.

  Espruino board and pic connected to the same power source with the same ground. I have tried more than 10 capacitors, but result is the same. I can only guess that all my capacitors are broken. Tomorrow I'm going to buy new capacitors.

  Capacitors code is "104" I think I'm using the right one.

  Do you have any other idea?
