Old versions of flash apps fail to parse / send correctly #2

Closed jherning closed 3 years ago

jherning commented 3 years ago

I tried flashing old versions of a couple flash apps from TI (finance, statle) to an 89. These seem to contain a license as well as the program data to send to the calculator. It would be nice to get this working, but it is not a high priority as link68 can successfully send the most recent versions of these apps from the TI website. It appears TI removed the license data (probably because they are no longer selling any of the apps).

The old flash files may help resolve some ambiguity in the flash file format from the Link Guide as well (i.e. what flash files with multiple headers look like).

Current dev version now skips over the License block but instructs reader to use a hex editor or TI software to read it. Leaving issue opened to decide if it should be be displayed and assented. I plan to check the operation of TI Graph Link in this regard.

Dev version now asks for acknowledgement of the license to continue.

For the record: flash files with multiple header/data pairs seem to just be concatenated, as one might expect.

TI Graph Link v2.1 (Aug 2000) fails to parse these files as well. TI Connect 1.2.1 sends the apps without any prompt, so I am removing the interactive prompt but leaving the warning.
