Hi All, Thanks for your continued support and cooperation. I successfully ported YAFFS2 on MIPS platform and able to execute binaries from yaffs2 mounted directories. When I enable HIGH MEMORY configuration from kernel, only for *large binaries (>1MB)*, it is giving "*segmentation fault*" error. With HIGH MEMORY disabled is works fine. With yaffs2 log enabled (*echo "+all" > /proc/yaffs*), this problem can not be seen and *its working fine for large binaries* also. I could not find a way to debug this issue. Looking forward for your response. Best regards, Saquib
