[okl4-developer] build.py generates overlapping memsections

[Lukas HANEL]

Hi

with OKL4_2.1, the following error happens when building OKL4.

./tools/build.py machine=nhk15 project=iguana  wombat=True debug_trace=1 
verbose_str=True

[XML ] build/images/weaver.xml
[ELF ] build/images/image.elf
Error: Virtual Memory: Parts of "/vmlinux/vmalloc" 
(0x80a00000-0x80dfffff, size 0x400000) overlap with "/vmlinux/rootfs" 
(0x80500000-0x80a77fff, size 0x578000).
scons: *** [build/images/image.elf] Error 1
scons: building terminated because of errors.

can you explain the problem and provide a fix?
