Entering aarch32 state through software instruction

Naveen SR

Hi,

I have a 64bit application running on armv8(foundation model)

My question is

1. Can I link aarch32 library to aarch64 application ?

2. Is there a way to enter aarch32 state when application is running in aarch64 state in Exception level 0 ? I tried ERET instruction, but I got Undefined instruction and Illegal instruction error.

Thanks,

Naveen
