Q about using AArch64 gdb with target running in AArch32 state

Hi,

I start to use Linary AArch64 toolchain recently and just joined this maillist. I went through some of the archived threads but didn't read all of them. So bear me if I'm asking dumb question or old question which had been answered before.

For our use case, we are running the gdb client at early state of boot. So the ARMv8 target might be running into any EL and into either AArch64 or AArch32 state. My questions are:

1) Is the aarch64-none-elf-gdb.exe good for both AArch64 and AArch32 or I have to run the arm-none-eabi-gdb.exe if the target running in AArch32 state?

2) If the target is in AArch64 state, can I use the aarch64-none-elf-gdb.exe to load binary built for AArch32 to the target?

I'm really appreciated if anybody can help me on these two questions.

Thanks in advance,
