getting the invalid org range error; don't know why. Searching my [spam] off on this forum..

Try recompling your program without the bootloader part
just your test code comment out anything to do with the bootloader
and see if you get the error

I don't get that error then.

[BOB_SANTANA]

It must be a problem with the program space left for your bootloader

Have you tried it with the pre complied hex file and loader that i sent you?
Did it work ?

what about 16f877a?

I've tried a few times using Tiny bootloader...but it is not working

This thread describes the same problems I'm having, trying to get the ccs bootloader to work with a PIC16F883. I get the message "timeout while downloading". Using a scope, I see that nothing has been sent from the PC at all, it hasn't tried to communicate with the target device at all.

Please help!
