Subject: dynamic linker command line invocation

Hi All,

I am trying to add ldso functionality in my kernel. I am loading the
dynamic linker "ld-musl-arm.so.1" into memory and passing the other
application as command line which requires the dynamic libraries but the
linker is generating fault during stage 2 "__dls2" at some random location
0x464cc57f.

I am fairly new to dynamic linking code and trying to understand _dlstart_c
code functionality. Can any one explain what are the command line arguments
dynamic linker expects at this entry point ? I am giving numArgs = 1 and
argv = app.elf after loading "ld-musl-arm.so.1" into memory ? Is this
approach correct ? Do I have to also load app.elf into memory or the
dynamic linker will take care of loading it ?

Thanks,
NJ
