SainT Posted June 10, 2020 Share Posted June 10, 2020 (edited) This is a command line tool for uploading and executing files on the JagGD. Usage: jaggd [commands] -r Reboot -rd Reboot to debug stub From stub mode (all ROM, RAM > $2000) -- -u[x] file[,a:addr,s:size,o:offset,x:entry] Upload to address with size and file offset and optionally execute. Prefix numbers with $ for hex, otherwise decimal assumed. -x addr Execute from address So, for example, if you had a bin file which loaded and executed at $4000 with no header, you'd load and execute it like this: jaggd -rd -ux myfile.bin,a:$4000,x:$4000 I will be expanding development and debug type support as I get the time. It's something I want myself, so it will happen eventually. JagGD.zip Edited May 4, 2022 by SainT Updated attachment. 8 3 Quote Link to comment Share on other sites More sharing options...

I also need to get together some code showing how to use the other features of the jaggd in your own code. So many things on my todo list! ? 1 Quote Link to comment Share on other sites More sharing options...
+cubanismo Posted June 13, 2020 Share Posted June 13, 2020 On my phone or I'd look in the zip to be sure it isn't there already, but I have to second the request for source and/or a Linux build. Source is best since I don't like running a USB cable across my floor (there are small children who like to trip over such things running around), so I use a raspberry pi/arm board to connect to my Jag, so x86 binaries make things hard. No rush, tend to your pre-orders and family stuff first, just noting where the request is coming from. My skunk and BJL options are working fine for now ?. Also happy to help port to Linux if you just want to share the source. My day job is writing Linux drivers. I can't test until GD's are available to people not on the pre-order list in the US though, so it might take a while ? And speaking of Linux and/or OS X support, it's hard to type '$' on the command line there, so supporting a '0x' prefix as well for hex would be another nice feature. 3 Quote Link to comment Share on other sites More sharing options...
bodgit Posted June 23, 2020 Share Posted June 23, 2020 I imagine using something like libusb will probably hide most of the USB magic and make it portable to any other platform that supports that, rather than natively try and support say, Linux and OS X's different USB frameworks. Typing a $ isn't hard, it's just that the shell will try and interpolate a matching environment variable, so either escape it with a \ or quote it with single quotes so there's no interpolation. Having said that, I also prefer 0x notation to denote hexadecimal numbers ? 2 Quote Link to comment Share on other sites More sharing options...
+cubanismo Posted June 23, 2020 Share Posted June 23, 2020 Yes, typing it is hard because you have to remember to escape it. ? Agreed use of portable libraries when possible is ideal. 2 Quote Link to comment Share on other sites More sharing options...

I assume you have since seen that the zip only has a Windows executable, as we expected. I would buy this as soon as it had Linux support for game dev. Source would be ideal, but I'll take an x86 bin; however, having an ARM bin in addition would be extra nice, in lieu of source. I have some specific Jaguar dev tools and games I've been meaning to create. I had an official Jag DevKit back in 95, but was too busy with my web startup. I'm ready, now. 2 Quote Link to comment Share on other sites More sharing options...

If someone were to write a replacement for the Atari+Alpine debugger that could break, disassemble, and single step the 68k AND RISC processors, I'd get pretty excited. Also, if there were ponies to be had, I wouldn't say no. 3 Quote Link to comment Share on other sites More sharing options...
+BitJag Posted June 24, 2020 Share Posted June 24, 2020 Thanks for all your work on this @SainT! I am also interested in Linux support if possible, or at least sources so I can build the tools myself. It has been great to be able to do Jag dev in Linux with the Skunkboard, and it would be great to add the Jag GD to my little workforce. 3 Quote Link to comment Share on other sites More sharing options...
SainT Posted June 25, 2020 Author Share Posted June 25, 2020 I will sort out source at some point for this, needs a bit of a tidy first, then it should be easy to port to other platforms. 3 1 Quote Link to comment Share on other sites More sharing options...
swapd0 Posted May 3, 2021 Share Posted May 3, 2021 Now I'm a bit busy but I was wondering... Mac version? ? 1 Quote Link to comment Share on other sites More sharing options...
+CyranoJ Posted May 25, 2021 Share Posted May 25, 2021 For drag and drop icons on the desktop.... Create two batch files on the desktop: For ROMs: JagSDCmd.exe -rd -stub -ux %1,a:$800000,x:$802000 For ABSs: JagSDCmd.exe -rd -stub -ux %1,a:$4000,x:$4000 Just drop the ROM on them and off they go. 2 2 Quote Link to comment Share on other sites More sharing options...

phoboz Posted December 24, 2021 Share Posted December 24, 2021 (edited) I am trying to upload, and execute the 3D renderer demo from the Official Jaguar Kit - August 4, 1995 (the latest one Atari made) It works fine to load it from SD cart, but it does not work when I try to upload it using the jaggd command line tool over USB (I confirmed it works for another file) I use the command: jaggd -rd -ux DEMO.COF,a:$4000,x:$4000 This is not good for me, because then I have to move the SD card from the GameDrive to the PC, and back for every small change. E.g. it will take forever to develop a game like this, and I will certainly break the SD card slot at some point. @SainT, could you please look why this file cannot be executed when uploaded, while it works to run it from the SD card? I provide the compiled file (it is made from open sources of the Jaguar devkit anyway) DEMO.COF P.S. This file does not work in an emulator, so I have to use real hardware for development.

SainT Posted December 24, 2021 Author Share Posted December 24, 2021 (edited) Try without the a and x params, it should pick those out of the cof I believe. And one other weird thing, I found I couldn’t use $ no matter what I did from a makefile, so ended up just using decimal for address and execution address.

phoboz Posted January 3, 2022 Share Posted January 3, 2022 (edited) @SainT, would it be possible to get a Linux build of the jaggd tool, or a source code version so it can be compiled for Linux? Edited January 3, 2022 by phoboz 1 Quote Link to comment Share on other sites More sharing options...
SainT Posted January 4, 2022 Author Share Posted January 4, 2022 I do need to release the code for it, I think, so people can do their own Mac / Linux versions. I don't use either platform regularly at all and not a great deal of time to familiarise myself and port it. I'll try and get on to that this week. 3 1 Quote Link to comment Share on other sites More sharing options...

+cubanismo Posted April 30, 2022 Share Posted April 30, 2022 Just keeping this on your radar @SainT as suggested. Happy to work on a Linux port once source or even just some informal documentation of the interface is available. 1 Quote Link to comment Share on other sites More sharing options...
+cubanismo Posted May 3, 2022 Share Posted May 3, 2022 Got tired of waiting. It took me all of one night to figure out how to use Wireshark to capture the raw USB traffic, reverse engineer the USB protocol out of that, learn the libusb-1.0 syntax, and rewrite this utility from scratch borrowing a little code from JCP, and yes, clean up the source a little for publishing, just so I could use my GameDrive from Linux. https://github.com/cubanismo/open_jaggd/releases/latest Let me know if I got anything wrong. I've only tested on one GameDrive on one computer so far, but it works for me with all sorts of roms, COFF/ABS/JagServer files. 4 2 Quote Link to comment Share on other sites More sharing options...

Ericde45 Posted May 7, 2022 Share Posted May 7, 2022 i mean : send a file from the PC using command line tool, to write it to the GD SD card , so without removing the SD card from the GD to plug it into the PC sending a file directly to memory and run it is great, currently i use that a lot when testing my code on real hardware but sometimes i need to restart and watch it from the beginning of the execution, and my pc is not just near my jaguar ( i have a nice long usb cable ) 1 Quote Link to comment Share on other sites More sharing options...

Mean while I use a SD card expander to avoid wearing out the release mechanic in the GD. But during intro testing I need to rewrite the SD a dozen of times. Actually it would be cool to write directly into this RAM which holds the ROM for boot. And of course being able to start this via jaggd. Same for booting a game by sending the name: jaggd -b demo.j64 Edited May 7, 2022 by 42bs Quote Link to comment Share on other sites More sharing options...
