USB Bootloader.

[ardhuru]

For this chip, you have to hold down PORTB.4 to get it into bootloader mode. Then I can program and verify correctly. The hex I was using assumes a 12 mhz oscillator, and uses PLL to bring it up to 48.

Once my blinky program is loaded, I can hit the reset button, and my LED starts to blink.

Thanks a ton! Wasnt aware of the PORTB.4 switch, works perfect.

Now, if I can just figure out why I get the error message, despite the code getting programmed alright!

BTW, what hex file are you using for the bootloader? And, the Olimex schematic shows a 20 MHz crystal (the same as mine); how did you change the hex file to accomodate the 12 MHz?

Thanks for the help!
