Hello All
Concerning the bootloader, does it make a difference which bootloader
I use? Or are they all the same?


Thanks

You need an actual ICD2 bootloader, one that MPLAB will recognize.

See next post for details...

Well, how many have you found?!

You need an actual ICD2 bootloader, one that MPLAB will recognize. There's one for the 16F877, and one for the 16F876 included with your MPLAB installation.

If you're using a 16F876A, there's an updated bootloader circulating (see attached).

I think you can use the 16F877 bootloader with the 16F877A, but don't quote me on that.

I built mine with a 16F876A and the attached bootloader.

You are not quite right.
There are two bootloaders, one for 16F876/16877 (can be found in MPLAB dirrectory) and the one for 16F876A/16F877A (that 661.hex you attached).
It doesn't matter if you use 876 or 877 in your design (only that 876 is smaller), it works the same.

I am quite wrong! :lol:

I stand corrected!
