Debug A53 with Virtual memory

HSchill — Mon, 14 Feb 2022 16:38:43 GMT

I'm trying to debug a S32G274A Cortex-A53 core 0_0 with MMU turned on
Have anyone managed to read Virtual memory with the S32 Design studio and the S32 Debug probe?

The Memory Spaces view doesn't support 64 Bit virtual Addresses ...
Can that be changed (in configuration) ?
As soon as more than 32-bits is entered in the dialog box the Select key get "grayed"

btw.
Peripheral - view works
Disassembly - doesn't work when not having a flat map

Regards
Hans

Hello Hans,

We are investigating this issue. Could you please provide some sample application which has the MMU turned on so we could reproduce on our side and as well confirm possible solution would work for you?

Best Regards,

Mike

Hi,
The easiest would probably to load any aarch64 linux-kernel
or a much smaller approach - little kernel
it can be found at https://github.com/littlekernel/lk

If you want I can send you a little kernel build for the S32G274A EVB
that can be booted from u-boot or TF-A

Hans
