Jaguar 0.6-alpha Assembly Guide

[Fred]

You need an application that talks to the BDM using the driver and in turn talks to the BDM pin on the MCU and writes data to it. Various people seem to use various apps for this, USBDM, codewarrior, and some freescale utility. I've only ever used the USBDM app on Linux so I'm not much use to you, as previously mentioned.

Guys, try this. The 118MB download has all sorts of stuff tucked into it.

Its got a butt-load of programmers in it. Maybe one would work, ie the HCS12 programmer or the Coldfire Vx programmers..? Fred, Andy input?>

[Fred]

FlashProgrammer_HCS12 is I think what I use on Linux.

[pishta]

Win users can run Ubuntu inside win7-8 with VM. installs in 5 clicks and looks like it runs on your windows desktop in unity mode. maybe worht a shot so you can see exactly what Fred uses and maybe even a few script downloads. Copy and paste his script and let her rip.

I'm hoping Andy will chime in at some point because he did mention Code Warrior on the week end and I have the free and restricted version V5.9.0 build 5294 installed, if that will work. I know absolutely nothing about Linux.

I may be making some progress here.

In the list of programs within Code Warrior I found "HCS12 Programmer". I opened it and it was able to find the target MC9S12. I was able to select Sean's hack S-19 but when I attempted to download to the MCU I got an error message "Program data not within target flash memory".

What is the step by step procedure to use the HCS12 programmer software?

Oh, I forgot to mention. Does Jaguar have to be powered up for any of this or does power come from the USB?

[pishta]

Step 5 says load up through bdm, step 9 says complete p/s circuit so i think its usb powered for load. Did you install the bootloader or is this what we are talking about? Bare boards need bootloader injected via usbdm, smd come with it already installed. Keep talkin'..looks like you are point man on this.

[Fred]

It could be the format of the file isn't appropriate for your freescale application. I think Andy said that it was fussy about S19 file types?

For power, it's not a bad idea, but you can, and I do, get away with just USB power for it, provided there are appropriate caps installed. Try without first. If it can talk to it, as you say it does, you're probably OK to burn without power too.

You ARE making progress, though. Good work! :-)

Fred.

PS, pishta, he's *trying* to install the bootloader, that's what this is all about.

[pishta]

Bootloader, gotcha. Thought S19 file was the executable. Proceed......
Im going to be right behind you tomorrow if i can source the caps locally for the board. Keep your progress documented here please.

OK. Here's the latest.

I finally got the HCS12 programmer program to load Sean's S-19. I'm not sure how or why.

I was able to get Fred's bench test S.19 into the EMS loader program but when I try to download it is tells me it is not getting an acknowledge message from the serial monitor. If I look at the history it seems like it's trying to replace Sean's S-19 with Fred's.

Is there some way that I can confirm that the serial monitor is functioning before I try to load Fred's S.19?
