can anyone please help to solve this issue.

Thanks.

You won't find support for vendor SDKs here. They might be based on old OpenWrt code, but it's nowhere near what OpenWrt itself offers. This forum is for official OpenWrt.

Better ask your vendor for support, they offer the SDK. What sometimes helps is using an older OS, older code doesn't age well if you compile it with newer compilers.
