PIC 18F4520 [solved]

[nicorosen]

Hi, I'm trying to bootload the firmware from my device (PIC18F4520), but I always get the same msg:
"
Opening port Puerto de comunicaciones (COM1)@9600
Searching for bl . . . . . . . . . . . . . . . . . . . . . timed out
Closing port
"

I compiled the firmware 18F with MPLAB, as the "firmware manual" says.
Then I burned the .HEX through the JDM Progammer with WinPic800 and and everything went ok!
But when i want to download a program through serial port with ds30 Loader, i cant get the PC to communicate with the device.

I would appreciate very much if someone could help me?

Thanks anyway.

Nicolas
