Description rino4work 2020-04-09 11:00:53 UTC 
stat utility should report combined device id containing major and minor device version bytes.

I see it reports a single byte id instead:
# stat /
  File: /
  Size: 1376      	Blocks: 0          IO Block: 4096   directory
Device: ch/12d	Inode: 1           Links: 20
Access: (0755/drwxr-xr-x)  Uid: (    0/    root)   Gid: (    0/    root)

Change: 2019-11-27 17:24:56.000000000

I've failed to find if that's a special number that could be matched to real device id.
Assuming that may be a bug in busybox stat implementation.
