Serial1.setup(9600...) hangs on STM32 VL Discovery

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?

On the VL board you're communicating via Serial1 on pins A9/A10 to get a Serial console. Is it possible that when you call Serial1.setup(9600,{rx:B7,tx:B6}); you're just moving the serial port to another place, which means you no longer get a response?

What if you type setInterval("LED.toggle",500) beforehand - so an LED will flash on and off. Does it keep flashing after you issue the command?

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.

//device failed when I call x() but all the others worked good until this one.

Ok, thanks - I'll need to look into this. It's possible that over time the amount of free stack available in the VL image has dropped to the point where it's not really usable.

Thank you for your response Gordon.

I will change my board.

Yes, it's probably the best bet I'm afraid. The VL doesn't have much free memory with Espruino on it, so is quite limited
