while playing around with aarch64 mode I've seen my Raspberry Pi hangs at a specific instruction.
The compiler is generating:
Code: Select all
stp q0, q0, [x8, #224]
Does anyone could point me into a direction what might be a reason for this?
I've checked that the actual core is running in EL1 and that I've enabled to use FP/NEON instructions with cpacr_el1 register.
I've also cross-checked behaviour in lates QEMU version and there the code gets executed fine (no exception thrown or the like)
Thanks in advance for your support.
