[About]:
hexdumpmem is hexdump-like tool to dump memory and write memory. When
developing a system on a SoC, I usually need to dump or write
memory-map registers of the SoC for debugging. I write this program
to do it on my developing Android phone.
[Usage]:
1. Dump a memory region:
% hexdumpmem -a 0x1000
Memory region 0x00001000 ~ 0x0000116f
addr 0 4 8 C
