Can I use yod to mmap for a memory larger than 128M?

As far as I know, the system physical memory block size is 128M, but why can yod only allocate one memory block to mmap? Is there any other way to make yod allocate more memory to mmap?

My test method is as follows:
yod -o lwkmem-prot-none-delegation-enable -M 2048m -C all --mosview lwk ./maptest --verbose --type anonymous --size 4096 --num 32512

Test Results
Failed mmap. Cannot allocate memory
