PIC programming question

[njosnari]

I was looking into programming the bootloader onto the PIC, and I see that a lot of people are opting for the PICkit3, but I was thinking that maybe it would be useful for me to get an eprom programmer and upgrade some OSs in some other machines, etc. I don't have any experience with programming PIC or EPROM, and I'm not sure if programming these would be the same. Can anyone tell me if something like the Mini-pro TL866 would work to program both the PIC18F452 and an 27c eprom?

I have a pickit 3 and its been great, not had an issue with it for my older cores, the 452 works perfectly in it. i havent used anything else, i only just picked back up with the midibox kits, family life and work gets in the way. But programming the 452 in the pikit was simple and even I followed the instructions correctly and thats saying something!! lol

In case anyone stumbles across this with the same question, it so far seems that the  Mini-pro TL866 does indeed program PICs ok.

Is the Mini-pro TL866 supported in MPLAB X IDE? Didn't see it as an option?

I have one of those Pickit-3 clones from eBay and I haven't been able to get it working... (Uhg)

What's happening? My PicKit 2 just worked out of the Box by installing the drivers and build an adapter

I finally got my PicKit 3 working in MPLAB X IDE. 

I needed to manually configure the Pickit to supply source voltage to the PIC.

Interestingly it failed when I supplied 5V, but it works perfectly and consistently with a little less (i.e., 4.875V).  

So now I'm able to burn the setup_mb6582.hex files, which uses the memory range 0x3000 to 0x17fff, but I seem to missing the boot loader code?

Appreciate any suggestions and guidance...

setup_mb6582.hex you must upload via Midi and MIOS Studio

You also don't need Mblab, you just need the Programmer for the Bootloader  https://youtu.be/3EkNUa2nSDE Links in the description.

@Noise-Generator you are of course right my friend..

I spent way too much time trying anything and everything, except what was most obvious and directly in front of my face... Lessons learned...

Fortunately, now I can say that I've walked through the entire end-to-end process of creating the Master and Slave PIC Cores, including bootloader, MIOS OS & MB-6582 specific firmware, as well as setting the proper Device IDs.

I documented the experience here in case anyone else is interested: https://1drv.ms/w/s!AtmSvwylfFJaggnN1TtalEzGQK1C?e=sRlAiG (MS Word format).

Cheers and thanks again!
