My E2 is still in a box. Somewhere. I currently have other things on my mind, such as getting my hot water working...
Do we have a CVS (or other) repository anywhere that I can upload pblq to, in the meantime? There's stuff that needs doing to it, like support for the execute-code command that Otaku found, and the E3 support that... uh... someone hacked in (sorry, I can't find the message), and I don't think I'm going to be doing anything with it any time soon.
Plus, at some stage I presume people are going to want to start hacking ucLinux or big Linux...

Seconded, I'd like a CVS server for all our bits. (Though am in no place to set one up unfort. - sourceforge?)

Speaking of which, I've 'started' hacking LH79531/E2 support into the 2.6.11-hsc0 uclinux tree; I've just basically done the build/directory tree (i.e. not much) and I'll need to do the IRQ/timer stuff before it'll go anywhere. And do something about serial... But the good news is there appears to be a USB driver for the Cypress USB host chip on the E2.
I hope to get somewhere at the weekend when I might have some time. (Famous last words these days :( )
Cheers,
Matt

I'm an SF developer and have a bunch of projects there, and it works really nicely, although if we created a project I'd rather someone else did it (I'm already admining a bunch).
But is there anywhere more appropriate? http://cvs.uclinux.org, for example?

Huzzah. If we can get that working, then we can get huge numbers of devices working, including networking. And *that* would be very cool.
(I did have a look at porting ucLinux, but frankly, delving that deep into Linux gives me the heebie jeebies, and I port operating systems in my day job... when you get that far down, you find yourself spotting all the rough edges and cruft in Linux's design. I'd much rather tackle a BSD, but they all require MMUs.)
Is there a Linux driver for the sound codec?
Hello all, I have finally gotten round to building my max3232 interface for the E2's exp port, it seems to be working just fine running at 3v which i took from the 3v supply on the E2's board which i used for my Jtag leads Vref as well. But I have an issue with dumping the NAND flash, Im sure its just me being half asleep but what command should i be using to back up the entire 8MB of flash? I have compile pblq-02 but when I run: ./pblq readflash flash.bin 0x0 0x7FFFFF I get an error about the size not being divisible by 512, and if i try using a size of 0x800000 i get an error about an invalid size.
Id be extremely gratefull if someone could point out my no doubt stupid mistake and tell me what i should be doing to save the entire flash image so i can have a backup of my E2.
Thankyou en4rab

D'oh! That's my fault.
Line 142 of src/checksum.cc; change the obvious 0x7FFFFF to 0x800000.
Incidentally, you probably don't want to be using pblq to download the entire flash. The mechanism it uses to read the flash is extremely cludgy and horribly slow (we're talking 66 to 100 bytes per second).
You're far better off using pblq to save the first 64kB of flash, downloading Matt's shell into it, and then using that to get the rest --- it's much faster. You might even by able to download it into RAM and run it there --- Matt?

If you can get xmodem to work properly :( (I'm interested in success/fail stories on this)
But yes - if you can download it anywhere then jump to the first instr. (this is monitor.bin not monitor.pbl) it'll wake up.
