McLoader and 18F2580

[rwskinner]

I'm having a small problem using McLoader on a 18F2580 @ 20 mhz.

I have the standard Max232 set up with a Rx and Tx LED like my other projects. When I kick off McLoader and try to program, I see the RX led flickering quickly like normal, and McLoader tells me I must reset the pic.

I reset the pic, and both RX and TX leds are flickering quickly, just like it's programming, however McLoader is still at the "reset Pic" dialog.

If I close the "reset Pic: dialog, and click on program again while both LED's are showing activity, then the chip programs fine. I never had to do this on other chips.

Any tips are clues? Mecineque has been totally non responsive.

Are you driving your LED's with the same pins used for loader communications?

[rwskinner]

Yes,
The LED's are Between the Pic and the Transceiver, They go thru 390 ohm resistors to 5 volts.

Same as my 876 and 88 projects. Is this a problem?

How does it program without the LED's or any other load on the pins used
for serial comms?
