Does your working Xilinx design load into the Xilinx from a
flash device before you program the new image in with JTAG? If so, when you
load the new design via JTAG make sure that you select the “Pulse PROG”
option in iMPACT. Some Xilinx family chips only erase the part on power-up,
subsequent programming of the chip may require a forced erase. If your
original working image is loading into the Xilinx at power-up, then you load
the new image via JTAG, you may actually be overlaying the new image on the old
one. This can result in errant behavior of opb peripherals, a distinct symptom
is strange behavior of SDRAM in one design with normal behavior in another

Subject: [microblaze-uclinux] MicroBlaze restarting
this is more a
problem of microblaze but of uclinux but here it is.
I have a
working design. When I add my opb can core(to the OPB bus), the memory (SDRAM)
starts to behave strange, sometimes data is not written at the first time...
and the worst,
when it jumps
to SDRAM baseaddress, where linux image is copied, microblaze just restart the
initial program(the bootloader itself).
What the hell
is doing EDK? I just wanted an OPB peripheral more!
thanks a lot.

Out of tree compilation: autoconf + automake
I'm now facing a quite common problem.
I need to build an existing application (php-4.4.8) for uClinux on
The application uses autoconf to configure and automake to build, so I
would avoid writing a new Makefile to accomplish this (at least if there
would be any simpler way).
On blackfin uClinux I took as reference the file
Now I need to do the same for Petalinux.
I read the thread "GLib ... uClinux"
but that did not help much.
I would be glad if you could give me any advice on how to proceed to
compile a generic autoconf/automake application.
Many thanks for your time.
