Hi all,
As the title says i have managed to get the bootloader to work but after i load anything for the first time I cant load anything else onto it. the pic im using is an 18F6723 and im using uart2 for the bootloader.
the following is my settings file
The following is the test file I have been trying to load with the bootloader
Another thing, I tried changing the oscf to 8000000 and the osc to hc but when i did this i got the following error from the bl gui
Thanks in advance for your help
Liam
