Amicus 18 FTDI driver on W10?

[Dave]

Henrick, I have used the UMC Loader since it came out and have worked with David Barker on a few bug's I found in it. In fact as far as the Boot Loader goes, you have to manipulate some of the registers of the newer 16F & 18F parts before the Boot Loader will work. That is why David has allowed you to generate an .ini file to configure the Boot Load Builder for your particular processor.

Thanks Dave,
Guess it's time to figure that UMC loader out, never had the need before.

Dave,
If you don't mind me asking, are you using the UMCBuild application to create your bootloader .hex files or are you building them manually in MPLAB?

I've just read thru the documentation and have attempted to create a .hex file using the UMCBuild application but needless to say I'm struggling. The application says it can't find the MPASM executable, something the docs says it should be able to do if I have a working environment (which I do). I suspect the issue is that it's looking for MPASM.exe while it's now called MPASMX.exe.

I tried adding the path to MPASMX in the [PATH] section of the UMCBuild.ini but I get either Can't find MPASM executable or Can't find MPASM path. I tried making a copy of MPASMX.exe, renaming it to MPASM.exe but still can't make it work.

Would you mind sharing some of your knowledge regarding the UMC?

/Henrik.

Try renaming mpasmx.exe to MPASMWin.exe. That's the name of the old assembler.

[HenrikOlsson]

Well of course it is! Thank you for reminding me!
Making progress but still not all the way. Placing a copy of MPASMX with its name changed to MPASMWIN.exe and adding the following line to the UMCbuild.ini file made THAT error go away

MPASM=C:\Program Files (x86)\Microchip\MPLABX\v3.55\mpasmx

It then complained it couldn't find the MPLAB device path so I added the following:

DB=C:\Program Files (x86)\Microchip\MPLABX\v3.55\mpasmx

(Because, just as with the assembler, that's where all the device specific assembler .inc files are located - which I assumed was what it's looking for...)

But now it says No device file found for "18F452"

Anyone have any ideas?

/Henrik.

[Dave]

Henrick, I have my "Mecanique" directory mounted off my root directory on "C:/" drive. I have never used the "PATH" directives since I have mounted it on my Windows 8 machine about 3 years ago. Even when I had my Windows "XP" machine I had it mounted in the same way. Make sure the device you are trying to program in in the devices.ini file located under "Mecanique/MCSPX/MCLoader/umc/src/18F/". For new devices you will have to make new entries into this .ini file.

hi Henrik
I do it this way , it may not be the best way but it works for me

created folded
c:\myBOOTLOADER
made a subdir for each chip i use
c:\myBOOTLOADER\16f1825
c:\myBOOTLOADER\18f25k22
in each folder the modified config.ini file to suit that chip

to compile loader
copy chosen config.ini to c:\myBOOTLOADER
then using dos shell
cd to working dir
CD C:\Program Files\Mecanique\MCSPX\MCLoader\umc\build
run compiler
umcbuild.exe "c:\myBOOTLOADER\config.ini"

output is in c:\myBOOTLOADER\"chosen pic folder"

note
C:\Program Files\Mecanique\MCSPX\MCLoader\umc\src has two sub dirs
16f and 18f , in these are the device.ini files you may need to add your chips to these files if they are not included

Thanks guys!

Are you both using MPLABX/MPASMX or do you also have an older version of MPLAB installed? I thought I'd try to bloat this new computer down with all sort of software but that seems impossible to avoid. Microsoft won't properly support Win7 on new generation CPU(s), the Amicus loader doesn't work on Win10, the UMC loader doesn't work with MPLABX....it just never ends :-(

I'm trying to build a bootloader .hex for the 18F452 - which is what the default .ini file is configured to do. As far as I can see it's one of the default devices but I may be wrong. I thought I'd get that going first before trying to configure it for other chips.
