CCS Bootloader timing out |

Ok, i've read 99% of all the bootloader topics and i'm still confused.
I've loaded the CCS bootloader on my pic18f452, and i made 2 simple 4 line LED blinking programs. It loads the new program fine.
Heres my problem:
I want it to work on a software usart not the hardware usart. Is this possible?
When I try to load another program over the software uart, it always times out after 10 lines are read. I am using the siow.exe program that came with ccs compiler. If I just use 'open' then it won't time out, but it still doesn't work. Either way I use, the old program still works which makes me believe that no writing is being done at all. I've used a printf statement to show that it does read in the lines correctly, but does not write it onto the flash.
Anyone tried getting a software usart working with a bootloader and can push me in the right direction? |
