Hey guys, I'm planning to buy jornada 720. But would like to know if GPS devices will work with J720. If so, what GPS device should I buy? What cables do I need to connect to the J720? What software do I need to install? Any help will be greatly appreciated. Thanks. Neil

What software do I need to install? First, I know nothing about GPS. You have two way out of the machine: serial or PCMCIA (16 bits, not cardbus). If you get a serial device, there shoudln't be any driver issue, you just need the software. What software? No idea, but this question is not NetBSD specific: any opensource software should do it. A Linux/arm binary should work too. If you get a PCMCIA device, you need a driver. As drivers are machine indendant in NetBSD, the question is not hpcarm specific. Ask on netbsd-users, you might get a more accurate answer. -- -- Emmanuel Dreyfus manu <at> netbsd.org

Heads up: Thumb code working on NetBSD

This is just a quick heads up to let folks know that I now have a NetBSD kernel running on my integrator board (with ARM10e) that supports applications compiled as Thumb code. It's stable enough that I've been able to debug and complete a bootstrap of gcc (trunk) compiling to Thumb code. The size savings are quite impressive: On my shark the size of the cc1 binary is shark1:egcs [759] $ size gcc/cc1 text data bss dec hex filename 3677285 6432 330916 4014633 3d4229 gcc/cc1 Whereas on the integrator we see integrator:gcc [611] $ size gcc/cc1 text data bss dec hex filename 2727208 6392 330496 3064096 2ec120 cc1 which represents a 30.2% saving in code size. On v5t processors the Thumb binaries can make use of the same shared libraries as ARM binaries (provided that the libraries are compiled for v5t). The limited natural inteworking ability of v4t processors means that I don't intend to back-port this work to the older cores. I'll be starting to commit the changes shortly; most of them are pretty straight-forward. R.(Continue reading)

Nice. Does this space saving come with a performance gain or a performance hit? -- -- Gillette - the best a man can forget

It's normally a slight hit. 30% space saving when your instructions are 50% shorter means you must execute more instructions (about 40% more), but on the other hand you get better I-cache utilization, so it's not quite as bad as that in practice (in fact, some applications can end up being faster since the entire critical code can fit in the cache).(Continue reading)

Hello, I just wanted to show you all how _GREAT_ NetBSD was on the iPAQ, here's a comparison between usage of Plan9 and NetBSD, it's clearly obvious which is better, isn't it? :) http://www.brokendream.net/xh4/NetBSD/ http://www.brokendream.net/xh4/Plan9 This should clearly motivate all to try NetBSD on an iPAQ. _____________________________________________________________ yourname <at> digiverse.net http://www.digiverse.net
