Hi Jose.
Many thanks for your message. I looked into what you pointed out and
here is a decription
of what happened. I got the image.bin file generated finally but not
without going
through a bumpy patch.
To begin, I had no timer in EDK. Didn't see anything like opb_timer in
the system
assembly. So in EDK 8.1 (with the recent patches) I added opb_timer, and
checked
the option 'Only one timer'.
Then re-compiled the libraries to generate the auto-config.in
and copied it back to the path to uclinux-auto.
Then did a 'make clean oldconfig dep', followed by
'make xconfig' (followed all the steps in the Xilinx App Notes)
At this stage I didn't see any of the old messages and infact
I notice
#define CONFIG_XILINX_TIMER_0_BASEADDR 0xFFFFFFFF
in my autoconf.h file.
Then did a 'make'. Now I got the error complaining
about CONFIG_XILINX_TIMER_0_IRQ being undeclared.
So this time around I hacked the linux/autoconfig.h to add
#define CONFIG_XILINX_TIMER_0_IRQ (0)
Then did a 'make'.
This time the compile process went-on for a while till I got
an error of the sort:
/dev/null 2>&1 || exit 0
Making symlinks in include/
Making include/c++ symlink to compiler c++ includes
sed: -e _expression_ #2, char 21: Unknown command: ``Q''
ln: `3.4.1': File exists
make[2]: *** [all] Error 1
make[2]: Leaving directory
`/home/ashish/uClinux-dist/include'
make[1]: *** [all] Error 2
make[1]: Leaving directory
I noticed that there was a fix for this posted on the mailing list
(http://www.itee.uq.edu.au/~listarch/microblaze-uclinux/archive/2006/09/msg00007.html)
to comment out the portion in uClinux/include/Makefile
which I did, and finally obtained the image.bin file.
I have several questions/doubts: Perhaps these will enable me understand
the process better.
About opb_timer
-----------------
When I had no opb_timer in EDK why the linux compilation
complained about it? Clearly it should have known this
from auto-config.in file that there is no need to complain
about something that's not present in the hardware definition.
About missing timer interrupt entires
-------------------------------------
When I did add the timer opb_timer, why did I not get
the XILINX_TIMER_0_IRQ set in auto-config.in . In fact
it still doesn't exist there, I've entered the value
in autoconfig.h file as I pointed out earlier.
About the 'ln' error.
---------------------
I understand that people had patched up the Makefile to
avoid getting link errors that I found the fix for by
commenting, but these patches were provided in 2005, so
when I got the uClinux-dist and uClinux-2.4.x yesterday
why didn't they reflected the correct patches?
Thanks
Ashish
