gnupic: Thread: programming PICs using PROMATE II and dosemu

I need to program some 17C756 devices using a PROMATE II from a Linux box.
My attempts to do this using dosemu to run procmd aren't successful.  

I think that dosemu is configured correctly to allow usage of the COM
port, and procmd runs, but it takes a very long time for the program
information to be transferred to the PROMATE, and then the device doesn't
get programed correctly.

Any ideas?
Thanks,
Glen Mabey

What version of dosemu are you using?

dosemu-0.98.8.0 running on Debian GNU/Linux 2.2

I posted previously about getting Microchip's procmd program to
communicate with a PROMATE II via dosemu.  I've since upgraded to 
dosemu-1.0.1.0, and I'm still not having success.

I'm running dosemu as root, which appears to allow me to access the serial
port (/dev/ttyS0). 

Is anyone successfully using dosemu and procmd to program PICs?

Thanks,
Glen

I've used dosemu and the picstart to program pics.  I haven't used it
recently, but it definately worked with dosemu 0.96.  I just setup
dosemu for access to the right serial port, and things work fine.  It is
sort of slow, but I never compared it to native execution.

I have also run the picstart programming under wine.  That may be
another approach.  The current versions of wine will run some parts of
mplab without problems, but not all.  For example, I can't get the In
Circuit Debugger to work completely.

I found it was better to use picp which you can get at any good
web-site, namely http://www.cosmodog.com/pic/

It's a linux app that programs PICS using your PicStart Plus (PSP)
hardware.

As for the ICD, well if you care nothing for the debugging but would
love to be able to program in-circuit, just read a post on the Microship
tech forum under 14-bit Core.

it basically says that if you wire up yourself a port to connect to your
PIC in circuit (pins - MCLR, VDD, GND, RB6,7) then wire a 5 core cable
to the corresponding pins on your PSP. This will work UNLESS your
circuit surrounding the PIC loads the PSP to heavily. THe PSP has very
weak drive on it's VDD outputs to your PIC, so if your power it
externally (usually a matter of leaving it on) it should program
perfectly. 

NOTE: connect all VDD and GND, who knows which ones it needs and/or
uses. And this is not guaranteed, MicroChip spefically DO NOT recommend
this. I think because they don't think it will work (and it won't) so
don't expect miracles.
