Seems like it went to the right list to me

You really need to build your applications from within the uClinux-dist 
environment.  We haven't done the work yet to build a stand=alone uClibc 
microblaze gcc.

Just look in the uClinux-dist/user directory, find a simple example 
program, and copy the format of the Makefile etc, and it will be much 
easier for you!

Regards,

John

Re: Is gpio_test source available?

Hi Steven,

I've never put it into the main uClinux-dist because it's microblaze 
specific (and not particularly interesting! )  But anyway, the source 
and Makefile are attached.

Yep - this is because of a change in how platgen handled bit vectors 
(busses) from EDK3.2 -> 6.1.  I expect it's still the same in 6.2.  To 
get the GPIO working as expected under 6.1, you have to make some tiny 
changes in the kernel source.  It's messy, but anyway...  The better fix 
would be to isolate the changes in the MHS file, using the bus_split 
macro and so on, but...

in linux-2.4.x/include/asm-microblaze/mbvanilla.h, edit the line (abt 
line 50 i think)

#define MICROBLAZE_GPIO_DIR 0x0000FF00

to

#define MICROBLAZE_GPIO_DIR 0x000000FF

[Fwd: [uClinux-cvs] Re: Updating CVS to 2.4.26]

Hi folks,

Re: the attached email from David McCullough - some CVS maintainence 
going on for the next cpl of days, for now if doing a checkout or update 
from the uClinux CVS, use the tag:

cvs update -r before_linux_2_4_26

or

cvs co -r before_linux_2_4_26

otherwise you might pull a broken tree.

Regards,

John

Hi all,

I am moving the uClinux-2.4.x tree to 2.4.26 over the next day or so.
Hopefully it won't take too long 

mbvanilla_net under ISE/EDK6.2

Hi folks,

Has anyone tried building mbvanilla_net under ISE/EDK6.2?  I ran the 
revup utility first, which basically only touched the .mss file.

I'm building this purely under Linux BTW, haven't tried yet upgrading my 
winXP setup.  I have the latest and greatest service packs etc.

The results are very, very odd.  The HW platform and bootloader 
synthesise and upload fine, and I get the bootloader menu printing 
correctly, however when I try to enter a number (like 1 to boot from 
flash), the character received by the UARTlite is actually a '5'.  It's 
hard to explain - I type 1 on my keyboard (using minicom as I always 
have), but the character received and echoed by the bootloader is a '5'!

Any ideas?

John

Re: mbvanilla_net under ISE/EDK6.2

Hi John,

I have the design working on EDK6.2 SP1. I haven't had any problems.. I 
am attaching my EDK design file (same as mbvanilla_net, but DCMs have 
been changed)..

I use Windows Hyperterminal for communication.

Thanks for the reply - I think I found the cause and it's my fault (sort 
of).  I leave my insight board in SlaveSerial mode since I always 
download configurations from the PROM.  I had kept it in this mode but 
did a JTAG bitstream download - I think there must be some wierd 
interference between the JTAG download and the Prom... when I re-burned 
the prom with the new bitfile (generated in 6.2), it workes fine...

I'll be posting the a new version of mbvanilla_net to the website soon, 
for compatability with edk6.2 SP1.

Thanks again,

John

boot flash 8-bit wide

Hi all,

anybody uses a 8-bit wide boot flash on microblaze ?
Running out of pins, and seems a waste to connect a 32-bit
flash, when it is useless after boot anyway ...

cheers & thanks

different uclinux ports on microblaze

Hi all,

I'm trying to put up a list of different uclinux-mblaze ports.

Seems to me like a good idea, so the "newbies" can see, what
possibilities this FPGA core & uclinux has.

And for all others, working on ports, it would be probably
intersting to see, what other people are working on, and
probably even share ideas.

So, please send to me via PM (so we don't generate too much traffic
here) what you have 

Specifically, platform used (Eval, Devel Kit bought from, your own 
hardware). If it is a "standard" hardware, just the order/model number 
is fine. If you did something in house, please a short description
of the platform, if possible.

I wouldn't even mind hearing of platforms which didn't work at all,
because of ...

Any special devices you had to attach, brief desription.
(like IDE, Ethernet, USB, CAN, ...)

Status ? Work in progress is fine, it would be even (IMHO)
interesting of what people "dream" to do.

I would collect all the data, and forward a summary to John,
probably he can find a small corner on the uclinux-mblaze page

Great idea, I think this would be very valuable to the community.

If people are willing, it would also be great to bundle a .zip archive 
containing the EDK project that builds the platform (MHS, UCF etc etc). 
  I realise not everyone is in a position to do this, but for those who 
can it would be great.

Excess traffic is not something we have too much to worry about - this 
is not quite the LKML...yet

I can kick it off with mbvanilla_ddr and mbvanilla_net
