Recent 5600s have PXA255 processor?
« Reply #15 on: January 23, 2004, 05:42:53 am »
There are still more people reporting that they have just got a PXA250 5600 than the new PXA255 (in fact only 2 people have reported getting the PXA255). So I don\'t think Amazon could guarantee anything about which version of CPU you would get.

In the ZUG Downloads, in the 5600 Patches area there are some specially compiled kernels that do not include the workaround for the PXA250 bug. This workaround effectively halved the speed of the PXA250 5600. These kernels let it run at full speed without any apparent instability. Lots of people are using them now and no one has reported any crashes as a result. In fact the Dhrystone benchmark gave better results for the 5600 with the special kernel than a C760 with the pre-emptive kernel, although it\'s not exactly a fair benchmark comparison.

tummus -] if you work in a \"Global Supply Chain of a multi-national telecommunications equipment manufacturer\" then do you have any contact that will do an upgrade? apparently it\'s just a drop-in to change from a pxa250 to a pxa255... :-)

I wish  . We have outsourced most of our facilities and the IC stuff went with it. Besides which all the managers round here are mean and probably wouldn\'t let me do something like that.

\"Drop-in\", is a bit of an understatement.  these cpu\'s have 256 pins in an area 17x17 mm. Removing the old chip without damaging the board could be tricky. Mounting the new chip would require specialised equipment including X rays, to ensure that the chip is alligned correctly. Unless you know someone who has access to the equipment and the skill to use it, it would probably be more cost effective to buy a C860 or wait for a SL6000, than to have this done. You would also have the problem of getting hold of a pxa255.

Just to add to this, my Zaurus arrived from Amazon two days ago and it says on the box PXA255 Processor Version.  So I suggest to Guest that you contact Amazon and perhaps try and get them to exchange it for one with the PXA255 rather than the PXA250 processor as they are obviously available.

Given that two people (me and meangene) have just recently got PXA255s from Amazon but one person (anonymous Guest) got a PXA250, I imagine that Amazon just has a pile of them in a warehouse somewhere without any differentiation being made between PXA250 and PXA255 so whoever is in charge of packing it just grabs one and sends it off.  But if you tell them that they gave you the wrong processor they might be more careful and be sure to put the right one in.

Given the fact that \"the box say\'s its a PXA255\" have you actually verified on the hardware that this is so.
ie run \"cat /proc/cpuinfo\" from the terminal.
Sorry but  I am very hesistent to believe this just because two people are saying the box lists the PXA255.

Actually Felicity_Palmer makes three reportings. The other two people did give the output of \'cat /proc/cpuinfo\' and it did indeed say they had the PXA255. It was inevitable at some point that Sharp would have to make the switch as their stock of PXA250 would run out at some time. But obviously Amazon still has lots of stock of the PXA250 5600s at some of their warehouses.

I wouldn\'t be too bothered about gettting a PXA250 5600 as the workaround for the PXA250 CPU bug can be turned off without any apparent consequences other than getting the full speed out of your 5600. I don\'t know what the fuss was all about as I haven\'t had a single lockup with the special kernel and I have loaded it quite heavily with benchmark tests, playing graphically intensive games, DivX videos etc.

For the uninitiated how do I install the special kernel (I do not know code). I will be loading the update from Sharp tonight on my Zaurus. Is this the special kernel or is it something else? Also, what alternative ROM works for the 5600. It looks like the Open Zaurus does not work for the 5600. Also, how do I run cat /proc/cpuinfo from the terminal. Showing my ignorance how do you do that? Brad.

I would keep it for the price it is a good deal, just flash the rom up to 1.32 and apply this kernel update http://www.zaurususergroup.com/modules.php...q=getit&lid=165

I contacted Amazon, they said they had no idea which processor they were sending out, nor would they look at the box if you told them you wanted one or the other. They said all the information they had was on their web site. Guess it is too much to ask for them to actually inspect the product they are sending out. Oh well. It is still a good deal.

It\'s not THAT big of a deal.  Most of the people that complain don\'t even own the 5600, they just think it sucks because of the bug.  I have a 5600, use it every day... network with it, write scripts on it, interface with all sorts of servers and am never really affected by the bug.  Maybe in 5 years, I will get the newest sharp... If the 6000\'s bring a dramatic drop in 5600 prices maybe I will get a second.

Don\'t believe the hype.  There are many people who actually OWN 5600\'s who are quite happy with them (tumnus?  Can I get an amen?)

I\'ll give \"guest\" an \'amen\'! As a fairly new owner of an Amazon 5600 with a 250 chip... I have mine on a wireless network. Opera is fantastic,! I now have slrn reading newsgroups. I\'m getting back into linux programming. And last night I got doom to run. I play my mp3\'s, stored on my PC\'s drive. I can read my \'pda\' books. And best of all, I\'ve got a linux machine in the palm of my hand!
I can\'t say if mine is slower than a 255? And I don\'t really care! It works, and works just fine for me, and I love it. I\'m just sorry I didn\'t buy one a long time ago, even if it would have been a 5500 or 5000...
Or, you could wait for the 6000, or 7000 or 8000... Just keep waiting. There will always be a better model in the wings. Look at Sony. They up their models once a month and all the clie geek moan about having to get rid of their current ones to grab the latest-greatest...
Yeah, I do envy the 7xx,8xx owners for the clamshell design and resolution, but not enough to sell mine and buy one. I\'ve got a 5600 and I\'m happy with it. If I find something it can\'t do, well, I\'ll find someting else it can...

I just recently purchased the 5600 from Amazon.... it has the 250.  But I have not experienced any \"odd\" issues (that I didn\'t introduce myself).

I bought one about two weeks ago from Amazon for $299. According to the box it has the PXA 255.

Note: cat /proc/cpuinfo shows:  Intel Xscale-PXA255 rev 6 (5.1)
