Not quite understand the question. Then what do you expect to see here?

hello
I’m sorry, maybe I wasn’t clear.I’m just wondering why the memory seen by the command “cat /proc/meminfo” is less than 64GB, he only has 56GB

This is similar to the answer of this old post.

JP 5.0.2 missing ~1GB volatile memory

there are many improvements in rel-35. the memory missing is allocated to optee, uefi and for some inter-r5-shmem usecases. Not possible to be made available in rel-35. You can stick to rel-32 and use upstream kernel to retain the 240MB of space and also move to latest kernel
