QNX kernel segmentation fault
Hi all
I’m using QNX Momentics 6.4.1, QNX Neutrino 6.4.0 BSP for the AMCC PPC440 EP/GR (bsp-nto640-amcc-ppc440ep_gr-evk-trunk)
in our custom PPC440EP board (with a few changes) and the procnto-booke micro-kernel. The bootloader is u-boot-2009.11.
Qnx(6.4.1) runs on our board well but before loading any application, qconn crashes after a while with following error
message: (Specially when I use Memory Information perspective in QNX Momentics IDE)
Process 4103 (qconn) terminated SIGSEGV code=1 fltno=11 ip=fe32a078(libc.so.3@_list_release+0x1d4) mapaddr=0002a078. ref
=91078038
When I run ( pidin –fM) I have following error :
# pidin -fM
Memory
Process 20489 (pidin) terminated SIGSEGV code=1 fltno=11 ip=fe3620dc(libc.so.3@strlen+0x0) mapaddr=000620dc. ref=
00000000
Memory fault
Questions:
1.In Yosemite BSP init_mmu () function wasn’t implemented, Do we need to define it, (Our Memory map is very close to
Yosemite)?
2.Do you have any suggestion about a debugging start point?
Thank you in advance.
