the memory overlap between iguana/vtimer and oklinux

Reply Threaded

Hello:
I configure the 2 oklinux instance and iguana/vtimer in the OKL4 system but
when i merge these files there is an memory overlap as following:

Error: Virtual Memory: Parts of "/oklinux0/rwx" (0x801b9000-0x80200fff, size
0x48000) overlap with "/iguana_server/vtimer/rx" (0x80200000-0x80206fff, size
0x7000).
Now printing a traceback.

size 0x7000).

In this system the memory calculation is like this:
name: virtual base=80000000 end=cfffffff
name: rom base=7900000 end=7ffffff
name: physical base=4100000 end=78fffff
name: /kernel/rwx base=f0000000 end=f00276cf
name: /kernel/rw base=f0028000 end=f002dfff
name: /iguana_server/rw base=80014000 end=80014fff
name: /iguana_server/event/rx base=80100000 end=80105fff
name: /iguana_server/event/rw base=8010d000 end=8010dfff
name: /iguana_server/vtimer/rx base=80200000 end=80206fff
name: /iguana_server/vtimer/rw base=8020f000 end=8020ffff
name: /iguana_server/vserial/rx base=80300000 end=80306fff
name: /iguana_server/vserial/rw base=8030f000 end=8030ffff
name: /oklinux0/rx base=80000000 end=801b8fff
name: unknown base=80000000 end=801b8fff
name: unknown base=80000000 end=801b8fff
name: unknown base=80000000 end=801b8fff
name: /oklinux0/rwx base=801b9000 end=80200fff

In the attachment there is my weaver.xml file. I think it could be fixed by
increasing the linkaddress of oklinux. But it seems that i can't modify
linkaddress of vmlinux from default 0x80200000. The vtimer link addrerss is
0x80200000
Thanks a lot.
