yes, its been a long time since an update.

A lot has happened.

The Telxon Stuff has been operational under X11 for a few months now, just its not something I think about a great deal now that its working.

currently working writing code.

Going back to Uni to finish my CompSci degree.

Joy!

FINALLY worked out the interface to the Telxon's Touchscreen - turns out that there's a 16550A serial UART sitting at 0x4220, IRQ 12 which backs onto the touchscreen controller.

Well, I isolated the XIP bug on the Agenda VR3 to be related to the Copy-on-write handling of ROM pages, and the fact that they're rejected by the WP Fault handler because they exist outside of RAM.

Of course, I don't know enough about the Agenda's guts, nor Linux's MM/VM guts to implement this myself, so I have to leave it to somebody else who can.

Consequentially, I'm handing back the Agenda to WzDD so he can do evil things to it once again. Maybe I'll hack again when somebody fixes the XIP stuff.

Annoying fact of life #1: eXecute In Place support on the Agenda VR3 is still broken. Its just not as broken as it has been.

The story goes there are problems with XIP and C++ - something, somewhere along the line, tries to WP the page, and kills itself... *BUT* only for C++ code, not for C.

Time to take a hammer to the code.

Well.... the hack has been a success.

For the uninitiated, this is the hack to port Qt/Embedded to the Agenda VR3 - something I started last week wednesday night for fun, and its turned out quite well.

The hack itself was finished on Sunday. There are a few things that need tidying, like the fact the cursor is still enabled by default on the Agenda for normal builds. This is trivial to fix. (single #ifdef in the qte config headers).

The patch itself is here

Please ask no questions for a few days - I have to catch up on work. If you want to play with this, I'm assuming you're smart enough to wrangle your agenda sufficently.

Oh, and TT have the patch already - they know. :) (Hi Emily!)
