Jetson MemoryTracker no memory data collected on jetson.

Hi,
I tested the MemoryTracker with cuda11.8 on both A5000 server(x86-64 ubuntu20.04) and nvorin(jetson aarch64 20.04). The memory tracker seems did not collect any information on orin. I have already copied the fatbin into the same dir as #9 mentioned.
The command is:
LD_PRELOAD=/home/yzhao62/sanitizer_samples/temp/compute-sanitizer-samples/MemoryTracker/libMemoryTracker.so:/usr/local/cuda-11.8/compute-sanitizer/libsanitizer-public.so ./matrixMul
The output of matrixMul on orin like blow:
[Matrix Multiply Using CUDA] - Starting...
GPU Device 0: "Ampere" with compute capability 8.7
MatrixA(320,320), MatrixB(640,320)
