Re: About Low MIPS on AT91RM9200.

Hello! You're second guy in the list (as I remember) who meet this problem.
It's seams to be a problem in u-boot.
And (as I remember) problem was with wrong bus mode in the control register
of the CP15. Yuo need an asynchronous mode. Hope this will help.

Wit best regards. YaVA.

Hi,linux-arm-kernel！

I got a board from www.lomx.net. I can run arm-linux-2.4.19/21 on it,The
bootloader is u-boot.

    The two kernel is both 29.79MIPS.

    Pls help me how to improve the low MIPS?

    I also search from the list, but no result.

Best Regards.

I've sent Trizeps2 patches to blob to Abraham van der Merwe
<abz <at> frogfoot.net> at the end of September 2003. Looks like they still
haven't been merged...

Could you please resend. I seem to have lost those patches.

Re: PXA263 Network Serial Protocol (NSSP) code, anyone?

The PXA263 SSP ports are well documented here (Chapter 16) :-

http://apps.intel.com/scripts-util/download.asp?url=/design/pca/applicationsprocessors/manuals/27863803.pdf&title=Intel(R)+PXA26x+Processor+Family+Developer's+Manual&fullpg=3&site=Developer

I'm assuming that there is something missing from the manual wrt NSSP ?

Unfortunately, I can't send you my audio code, as it's Bulverde based
and will be under NDA until Bulverde is released. Sorry.

Basically you want to set up the port in the following order:-

1. Set up GPIO alternate functions and direction for NSSP (only if the 
lines are shared with another interface)

2. Enable NSSP port clock. (may not be required on PXA263)

3. Set up SSP port with your protocol, framing, DMA, and timing
requirements. This will be dependent on the target device. Chapter 16
contains the bit definitions.

4. Set the port enable bit. 

You should now be able to either use programmed IO or DMA to read/write
the NSSP FIFO's.

How do you handle the problems with softfloat? I'm still searching for a
better solution than what we now have (nico's patch, which works only on
PXA). The discussion takes place here:

You could also send the patch my way.

Thanks,

Attached below. An updated version. Also contains a 16bit AMD flash
driver, and a PXA-reboot code and some optimisations from Peter Lueg (pl
AT dsa-ac.de). It might not compile or even apply directly to the current
blob's CVS. If you want me to bring it to such a condition, let me know,
but I'll need more time, obviously. Otherwise, you should be able to
trivially fix it yourself:-)

I don't. I rely on the existing in-kernel emulation.

Patches to bkpxa version of pxafb.

Hi,

I've got a couple of patches to the pxafb driver. They allow me to run
up the LCD on our board here, perhaps they can be added to the pxa-fb
patch in handhelds.org CVS. 

I will followup with an updated pxa-fb.patch if anyone wants it -- the
sum total of all the attachments was too big for the mailing list if I
included it.

I intend to continue fixing up this driver, as well as porting some of
the features from our 2.4 tree (in case anyone else is working on it)...

pxafb-registers
        add some more defines to include/asm-arm/arch-pxa/pxa-regs.h.
        They are used below in the named-registers patch
pxafb-dynamic-pcd
        use the get_pcd function from 2.4 to get the correct PCD. The
        one in the pxa-fb patch did seem to produce the right numbers
        and this was the easiest way to fix it. Includes a large comment
        because it took me ages to figure out where the numbers came
        from.
pxafb-dynamic-bpp
        Set the Bpp field of LCCR3 correctly for the requested bit
        depth.
pxafb-device-name
        arch/arm/mach-pxa/generic.c calls the device "pxafb", so the
        driver should too (rather than "pxa-fb"). In fairness I think I
        broke this the other day with my patch to the pxa-cpu patch.
pxafb-mask-interrupts

Could anyone send me the latest cvs release of blob ?

I can't download it because of a firewall

Thanks in advance.
