SV: [PIC] Unable to add / view Global Symbols in watch window when debugging (MPLAB-X)

[Jan-Erik Söderholm]

Hi.

Don't know if it help, but I once, many years, wrote a couple of web pages
that describes and shows the differences between abs and reloc code.

The pages are in Swedish, but maybe the code examples helps.
Actually, Google Translate produces a descent English version...

Hi there, Bob.

Call me stupid today, but I honestly don't know how to change my code to relocatable. Can you point me towards resources that describe the process of migrating from Absolute code to Relocatable?

I'd even go so far as to offer money for someone to take my existing code and massage it into the proper form. That would make it easier for me to migrate other projects to Relocatable.

Many thanks!

Content-Transfer-Encoding: base64Use relocatable code and the linker
ð­"‚‚ˆ‚’IÛHYœ˜ZYhat absolute code is a thing of the past (although I am
personally a fan of it). The problem you are having probably relates to
the fact that cblock simply defines some numeric values for symbols, it
doesn't really 'allocate' memory. It is more like "C"s 'enum' than
anything else (in fact, I have been known to use it to declare enums).

Good day to all.
The following is a post I recently made on the Microchip Forums. No
help there, so I'm trying here.
The only suggestion from the forum was to make sure that I had the
"Program in Absolute Mode"
box checked - it was. No other suggestions so far.
I am a long-timer user of MPLAB - all versions prior to MPLAB-X. Most
recent projects are built using MPLAB 8.92.
However, I want to use debug hardware that operates only with MPLAB-X.
I'm biting the bullet and trying to wrap my head around the new
paradigm. I've just upgraded MPLAB-X to version 4.05.
My current problem is that I can't see Global Symbols when adding
variables to a watch window. My source is straight assembler, built in
Absolute mode. All variables are declared using a "cblock / endc"
section in my code. I'm not using re-locatable code nor am I using the
linker.
How to force MPLAB-X to make Global Symbols available for use in watch
