i've walked through code and it seems i've found it in cmd/strings.c
strings
display strings
<addr> [byte count]
- display strings at <addr> for at least [byte count] or first
double NUL
does tftp add the "double NUL" if i do this:
tftp 0x80200000 filelist.txt
strings 0x80200000
or do i need to add ${filesize} to strings-command (if this is set via tftp)
