Hello all,

I have been working with TI Flash Studio, and I have the beginnings of a chemistry flash app going which loads and works fine on the emulator.  I have emailed TI (doesn't) cares and basically got a response that said that they'll think about getting back with me one of these days and maybe giving me a key to sign the app to put it on my calculator for testing purposes.  I will not belabor TI's attitude, as I am sure you all are already well aware of what it entails.

Anyway, in order to get the app out where I can test (and eventually distribute) it, I have downloaded the key files from brandonw's website.  I have also downloaded and attempted with rabbitsign and resign68k.  I am able to successfully sign the app (at least no errors are output and a file is created).  When I attempt to load the file to my calculator, however, I receive a "no matching certificate on the calculator" message, and of course it refuses to load.

Would any of you kind coders care to assist me in getting me up to speed on how to sign this app properly?

 

Any assistance would be much appreciated.

Thank you in advance.

Thank you for the quick reply.  It's an 89 Titanium with 3.10 AMS.  I have tried rabbitsign as well as resign68k.  They both sign the app without any error messages using the 0109 key (the free 89T app key) but, alas, when I try to load to the calc, it fails.

I hadn't tried wappsign yet.  I'll look around and see if I can find a copy of it.

What operating system are you using, and where can I find the Microsoft JVM? >< I wanted to get into 68K flash apps, but TI's Flash Studio requires the Microsoft JVM, which Microsoft can no longer distribute due to a lawsuit from 2001. Which goes to show that TI stopped caring about the community long before the TI-84+ came out.

Also, what exact calculator hardware are you using?

I'd like to write some new 68K development tools, but without the Flash Studio, I can't easily generate and dissect sample applications.

Ah, correction - make that hw version 4

I was wondering about that. I'm guessing that the 0109 key is like the 010A key in terms of usefulness and popularity. Speaking of which, why isn't USB8X signed with it?

Weird.  Have you tried installing any official apps from TI?

Oh, and maybe this is a silly question, but did you edit the application header to use the correct key ID?  I've never worked with TI's 68k development tools, but they presumably default to using the 14F03 key (a special key that's only accepted by their emulator and isn't used on any real calculators.)

Maybe because usb8x was last updated in 2007? 

HAH!  I found out how to do it!  It works  

For those who are curious - and I am sure one or two are - here's how:

Go into the install directory for TI Flash Studio.
Look around for a file called sdk-89.key
Obliterate it  
Create a new text file called sdk-89.key with the following:

Note:  That's three lines.  And thanks to Lionel for those numbers.  I got them from an IRC chat between him and BrandonW.

Build your app.

Load it onto your calc.

Worked for me!  YMMV

I don't read the entire board, I'm seeing those messages just now through the messages on the chan.
Yes, a way to have FlashApps signed by TIFS is fiddling with the sdk-89.key and sdk-92p.key files. It's even easier than using RabbitSign / resign68k if you have the source of the FlashApp.
But for compiling FlashApps, you have to withstand the horrible TIFS mess: buggy, limited, dependent on Microsoft's proprietary implementation of Java incompatible with the standard, etc.
