Sounds like a bit of a pickle you've got yourself into :D First off, the GP2X kernel handles partitions just fine, but the front-end only mounts the first partition by default. To mount other partitions, you'd need a .GPU to do it or (better) a serial adapter cable. There's quite a bit of...

You can set the speed of the port to whatever you like, within the limits of the chip. I would be surprised if it was not capable of 5Mb/sec for example. Just a case of setting the timing parameters. Of course, it's still way too slow for use as any sort of co-processor :)

It's 3.3V.

Err... I hate to rain on this parade, but SlackwareLinux is actually wrong :D The 2nd core does not run when you are in the menu, although it does run when running the media player. Also, the TV encoder chip is not enabled at any time. It is true that the encoder does take an extra 200mA or so...

BradN: be VERY careful with that dd method! I don't know what it will do about bad blocks in the NAND. Any NAND chip can have bad blocks anywhere except for the first page, and if you write the kernel image without taking account of them in the same way that U-Boot does, you'll end up killing...

AireTamStorm: Your comments about x86 are half-right, but you miss the point. Even though x86 is register-starved and its instruction decoding is appallingly complicated, so much has work has been done on optimising the architecture that it really does perform well. Especially with AMD's...

Hey Willei, Although the GP2X does take quite a lot of power to run, what you're describing is certainly not normal! Especially because one battery was quite a lot hotter than the other. It could be a contact problem, although you would expect the battery to be hotter at one end than the other...

DaveC: Sorry, I missed your post initially. I *think* the report about power leaking out of the TV-out circuit was mistaken. If it is true, then the base current drawn by the unit will decrease, but I think we just need to wait a bit before we can say accurately what effects the TV-out is having.

Something really cool that comes out of the results above is that, say your application is running at 100MHz on just the 920 core, and you need more grunt. You could up the speed of the 920 at a "cost" of 1mA/MHz, or you could use the 940 at a "cost" of 0.25mA/MHz. Now, using the 940 is not as...

You're wilfully misrepresenting what I was saying. I was commenting on your "Wolfenstein source" comment. Go to www.google.com, enter "Wolfenstein source", and I believe that you will see what I mean. This board would be a lot more useful to people like you, if you would learn to use the search...

The arrival of *any* port on GP2X is essentially a random event. It has almost nothing to do with how "hard" the task is, and much more to do with some developer deciding that he/she is in the mood to port the software. None of the developers I have talked to are interested in porting DOSbox...

I've already done some testing, and found that running the 920T at 200MHz takes about 95mA more than running it at 100MHz. That is, almost 1mA/MHz consumed by the 920T. To put it in context, the whole unit draws about 400mA when sitting at the menu with 200MHz, against 300mA at 100MHz. Running...

To set up the LCD controller when the clock is changed, follow this procedure: One horizontal scan line consists of 320 pixels, plus a HSync period of 84 clocks (by default) - that is 404 clocks. One vertical scan consists of 240 horizontal lines + 22 VSync lines - that is 262 lines or 105,848...

OK, we'd better put this one to bed NOW! The results from Hermes_PS2R's program are invalid, because of a bug in the code.void set_FCLK(unsigned MHZ) { unsigned v; unsigned mdiv,pdiv=3,scale=0; MHZ*=1000000; mdiv=(MHZ*pdiv)/SYS_CLK_FREQ; mdiv=((mdiv-8)<<8) & 0xff00...

Hey, don't be defeatist before you start! We get two types of "major major noobs" around here: those that puddle around and stay noobs forever, and those that learn a bit and eventually become non-noobs and contribute some cool stuff to the scene :). Remember everyone was a noob once! You will...

karmacop911: Of course, all SDK functions will be "importable" into assembly projects. In fact, you can compile the SDK code with -S to generate the assembly output, and then hack away on the assembly files if you like :) And I won't judge you, even though I believe that C is far superior to...

Oh, one more thing: both CPU cores run from the same base clock, e.g. 400MHz. However the cores have independent dividers from this base clock, and so they can run at different frequencies! It is perfectly possible to run the 920T at 200MHz while the 940T runs at 100MHz, the Memory Controller...

Quite funny really - Mr Mirko has spouted so much misinformation in this thread, and then Squidge shows how wrong he is, and now there's no response. Mr Mirko, no offence, but you have been dead wrong about some things in this thread, and because you have a fairly high profile in the community...

If your computer is hanging when the card is in the reader, then maybe you have a BIOS which allows booting from an attached USB device. Just go into the BIOS setup on your computer and turn that option off. Perhaps your partition table is bad. You could wipe it (I think) by typing # dd...

Try fdisk on the card, and see what it reports. I think that the GP2X does something very wrong as a mass storage device, and it's got me confused. If I plug the GP2X into my computer, I get one device: /dev/sdc. I can mount that, and if I run fdisk on it and print the partition table I get:val...
