[Flashforth-devel] fl+ in FF4.8

[Mike M. <mi...@mo...>]

We are nearing completion of our project, using FF4.8 on the 
PIC24FJ256GB110.
FF has proven to be a robust platform.
We have found and fixed some minor bugs, which we will later post.
Tovar has worked out a good interface to C that has C and FF cooperating.
When it is ready we will post it.

I am currently stuck trying to use fl+ to protect flash.
BTW: The words.txt file has the definitions of fl- and fl+ reversed.
I have a few variables that need to be in flash.  I would like to call 
fl+ at startup, locking flash.
Then, when the code needs to write to a flash variable, it would call 
fl-, write, and then call fl+.

The problem is that I cannot call fl+ from the word that writes to 
flash, or even from the same line at the console.  When I try, the 
routine LOCKED: calls an address error, apparently because it is not 
done writing?
Adding a long delay before fl+ does not work.
I can call fl+ from a new line at the console after the write without error.

Is there a bit or flag that I can test to tell when the flash write is 
done, before calling fl+ ?
