Hi All,
I'm attempting to use WiMAX Tools and WiMAX Network Service on an Intel IXP-435
processor (ARM-XScale, big-endian). The kernel is 2.6.36. The i2400 driver is
from the kernel. The tool-chain is from crosstools-ng and is uClibc based.
The i2400 driver loads and wmx0 is created.
WiMAX Tools cross compiled without any problems. Endianness and architecture
appear to be handled properly.
WiMAX Network Service needed some massaging to compile. uClibc doesn't support
backtrace; the backtrace calls were commented out. I noticed that
BMI_MACHINE_ENDIANNESS_LITTE and BMI_ENDIANNESS_LITTLE were hard coded into
Makefile.am/Makefile.in. This was resolved by fixing up the generated Makefile
after running configure. I noticed that BitmanCommon.h has __ARMCC_VERSION and
__arm. If either of these are defined, WiMAX Network Service fails to compile.
The _packed syntax use doesn't appear to be correct when __arm gets defined.
WiMAX Network Service compiles if __ARMCC_VERSION and __arm are not defined.
The resulting binary produces SIGSEGV in FSM_SetStateIfNotEqual when attempting
to get fsm->csLock. Debugging the problem shows that fsm->csLock is getting
corrupted when fsm->hWaitingStateEvent is initialized in FSM_Init. I assume
this might be due to alignment/packing problems.
Has anyone compiled/used WiMAX Tools/Network Service on Big-Endian ARM?
Thanks,
...doug
