Using Microcode Bootloader + CDLite + Hyperterminal

[milestag]

What bootloader file did you program into the PIC? I assume you had to edit the 16F876A file?

Does the bootloader interface identify the connected PIC okay when you click on Check PIC?

So many variables here, and I don't have extensive experience on this bootloader. I can only tell you what worked for me. Be sure to read all the instructions included with the program.

Dear milestag

Yes commucate is OK after i edit asm file by change micro from 16f877 to 16f877a and see below

radix DEC
LIST P=16F877a, F=INHX8M
xtal EQU 20000000
baud EQU 115200
__CONFIG _XT_OSC & _CP_OFF & _WDT_OFF & _BODEN_ON & _PWRTE_ON & _LVP_OFF & _DEBUG_OFF

I don't know what the problem is, maybe someone else here has seen it. If the error is from the bootloader, then maybe you will have to try contacting the author.

Does your code work okay with a traditional PIC programmer (EPIC, etc)?

Have you tried compiling for different baud rates or oscillator freq? Double check everything too. Make sure you had the right chip selected in MCS, etc. This is the hazard of freeware....limited or no support (you get what you pay for, right?)

BTW - Probably unrelated, but I always try everything I can think of....if you are using 20MHz crystal, then I believe you need to use HS_OSC instead of XT_OSC. Someone else here pointed that out to me on an earlier problem I had.
