Has anyone done any checking to see if we can increase the cpu clock speed? The chip should be able to run at 64mhz, but certainly 56mhz. It looks like we can generate something close from the 9294 chip. There are a few references to the divide by two of the clock. Is this something that can be disabled by software? I have already destroyed 2 webpals trying to do Vit's memory mod, so "micro-soldering" is out of the question. Any ideas would be appreciated.
I now have one webpal running at 65mhz. Neither of the keyboards work, but I hope that someone can point me in the right direction to fix that. I set up the unit to wget a script from my file server and run that right after boot up. The modification is fairly easy. Just lift pin 11 of U4 (the 9294G) and solder a wire from that pin to ground. I have written a program to use the clock without dividing by two. Details are on my website.
Since the 805x microprocessor on the webpal gets its clock from a divisor of the IO clock, changing the CPU/IO clock will
affect the timing of the code in the microprocessor that reads in the IR serial strean and outputs it to the webpal.
So, I think you will need to change the code (or some timing loop constants) in the 805x microprocessor code to the
IR keyboard work.
Cool. Regarding your notes about Debian packages, I'm just about to make a few of those too. But I've decided to leave all dependencies out - just make sure I install all I need for any given package. The reason I chose to make debs instead of just plain tar.gz files is that I have a way of removing/upgrading packages too if I need to.
Or maybe I should just start porting Slackware over. :)
