8 bit upgrade issue

[petesmart]

Hello team,

I upgraded FC7 today to include the 8-bit pic chip pack.

The purpose for upgrading was to make modifications to code that was previously generated in FC 6 for miac V1/V2

The first time I tried to compile to the miac device – compiled to C but froze on the next step. Hit the cancel button and retried and got the following error message

Code: Select all

Launching the compiler...
C:\Program Files (x86)\Flowcode 7\compilers\pic\bin\xc8.exe  --chip=18F4455 "gen control v9.c" --MSGDISABLE=359,1273,1388 --CODEOFFSET=800h --ROM=default,-0-7FF

Reinstalled FC 7 just to make sure that the licensing came down okay.

Any clues?

All the best

update - version FC7.1.1 Sept

Okay after a little further investigation – I decided to run FC 7 in administrator mode on my Windows 10 machine.

This time I got a little more error information

So it appears that compiling to hex using a NAS drive causes the problem above "UNC paths are not supported". To confirm this I copied the project over to a local directory on the "C: drive" and successfully compiled project to the miac.

I don't recall having the same issue with the pic 16 chip pack and compiling to the DSPic miac – will conduct some more tests and provide an update shortly.

****** update ******

Just conducted a test with DSPic 16 devices – compiles from the NAS drive ok.... 8bit pic does exhibits the error above...

any clues?

All the best,

Pete

Hi Pete,

Microchips XC16 compiler originated from their C30 compiler.

Microchips XC8 compiler originated from the HiTech PIC C compiler.

So while both compilers seem to be in a family their roots are very different and hence behind the scenes may be very different too.

There may be a way to make XC8 play nicely with UNC paths, maybe by mapping the network drive so it's no longer a UNC?

Thanks Ben... will give it a go and report

We have a workaround for projects on UNC paths.
A batch file is required, this is usually created in the compilers\pic\batch directory, for example picc.bat
The contents as follows:

Code: Select all

@REM $(chip) "$(outdir)" "$(target)"
@PUSHD %~2
%~dp0..\bin\xc8.exe --chip=%~1  "%~3.c" --MSGDISABLE=359,1273,1388 --FLOAT=32 --DOUBLE=32
@POPD

The Flowcode compiler options dialogue then needs the addition of a new configuration with the following settings:

Code: Select all

$(appdir)compilers\pic\batch\picc.bat
$(chip) "$(outdir)" "$(target)"

Create, save and set this as default, as shown in the image below.
