Problem in the flash of a mc9s08pl4 with usbdm

[Floppy01]

Good morning,

I wanted to program a mc9s08pl4, after writing a simple program I compiled and clicked on debug, the debugger cannot connect with the microcontroller, the error I get 'CORBA connection error'. I use usbdm. Can anyone help me?

This is the code I wrote:

Thank you!

 Is this a custom board?

Can you check that the DBM lines are correct, reset is correct, BKGD pin us plugged, VDD and GND

Yes, I mounted the mcu on the breadboard and connected the usbdm, the following is the circuit diagram:

i checked the connection, they are both connected also because i tried the same circuit with a qg8 and it works.

Can you check if the reset line is holding in low? did you see any signal on the BKGB line?

Please check all the connections, I am not sure if your USBDM is able to provide power to the board or if you also need to add power to the board.
