Hi Rich,
Here is the command sequence I used which generated the error.
tar jxf sources/linux-2.6.23.tar.bz2
cd linux-2.6.23
bzcat -dc ../patches/linux_2.6.23_or32_unified_simtested.bz2 | patch -p1
make menuconfig ARCH=or32 CROSS_COMPILE=/opt/or32/bin/or32-uclinux-
(exit with no changes)
make vmlinux ARCH=or32 CROSS_COMPILE=/opt/or32/bin/or32-uclinux-
or32-uclinux-sim -f sim.cfg vmlinux
This crashed as noted in my previous email. I then took Ethernet out of
the Linux config and ran the simulator without the Ethernet enabled (set
enabled to 0 in the Ethernet section).
make menuconfig ARCH=or32 CROSS_COMPILE=/opt/or32/bin/or32-uclinux-
(disabled the OpenRISC specific driver for Ethernet)
make vmlinux ARCH=or32 CROSS_COMPILE=/opt/or32/bin/or32-uclinux-
or32-uclinux-sim -f sim.cfg vmlinux
All then works fine.
For this I was using Or1ksim 0.2.0 patched for GDB 6.8.
Despite my earlier comments, it could be Or1ksim 0.2.0 is the source of
the problem. I believe the peripherals are one of the more recent
developments with Or1ksim and I think you are using a simulator version
closer to top of tree. This could well have bugs fixed in the Ethernet.
A diff between the eth subdirs of the two or1ksim versions would be a
good place to check. Sorting out all the Or1ksim issues, so we have a
clean top-of-tree is next, now I have GDB 6.8 almost complete.
Let me know if you need any more info.
I'll send you the sim.cfg file and a patch file for or1ksim 0.2.0 as a
separate message, since they are too large for the OpenRISC mailing
list.
ATB,
Jeremy
