In this slow economy may be this can help someone as well as myself.

I posted a job at eLance.com

I agree, that the bootloader examples are not particularly instructive. But by studying them thoroughly, you should be
able to understand the principle.

P.S: The bootloader example basically has ...

Sorry about that !
I was more interested to know if the #org, LOADER_END, LOADER_SIZE are correct, in relation to the start and end of the hex files !

CCS is OK but the examples do not spell o ...

I tried modifying the CCS bootloader for PIC18F2520.

I think I got something wrong with the #org statements LOADER_END etc.

Here is a summary of the files showing the values for #org etc.

An ...

Thanks

Sometimes one source can be used for several different mcu.

Is there a way to use a #define statement to output different file names ?

Or is there any way to change the output file names based u ...

I use the 4 channel BS442N version all the time for all types of PIC projects. I mainly use the POD interface digital inputs.
I just talked with Bruce and he emailed me a newer version of the DSO pro ...

Some time ago I purchased a Bitscope BS3100 and never had time to read the manual or play with it until today.

The BS3100 sounds like a reasonable solution for many slow to medium speed PIC projec ...

Using the CCS ex_bootloader the last line of code in the hex file looks like this:

:04070000FFD7000C13 // from the LST this is a RCALL 0700

The loaded applications first line of code in the hex ...

Yes.
The 'jump_to_isr' instruction will automatically handle both. This is the difference between using this, and a manual 'goto'.
What else are you going to put in the space between the jumps?. The ...

Only if you are using both.
If interrupt priority is disabled, the 08 address is used.

Yes I just noticed that.
I added #device HIGH_INTS=TRUE and tthe compiler generated this. ...

It doesn't.
To use interrupts, the bootloader, _must_ vector the interrupt jump, 'into' the real code. The following assumes only low priority interrupts are being used - otherwise two vectors come i ...

The compiler generates the normal dispatcher at th 0x208 address (this is what the 'build' statement tells it to do). You need to jump the physical interrupt, to this address, with the routine placed ...

The example is not clear about what happens to the original isr dispatcher.

Does this new isr() replace the isr dispatcher ?

The value LOADER_END+5 seems to be specific to the ex_loader example ...

I'm trying to move the application reset vector and interrupt vectors out of the boot block.

#build(reset=0x200,interrupt=0X208)
#org 0X0, 0X1FF {} // don't use boot block

This compiles, but t ...
