Christopher Haster	46b78de500	Tweaked tracebd.py in a couple of ways, adopted bdgeom/--off/-n - Tried to do the rescaling a bit better with truncating divisions, so there shouldn't be weird cross-pixel updates when things aren't well aligned. - Adopted optional -B<block_size>x<block_count> flag for explicitly specifying the block-device geometry in a way that is compatible with other scripts. Should adopt this more places. - Adopted optional <block>.<off> argument for start of range. This should match dbgblock.py. - Adopted '-' for noop/zero-wear. - Renamed a few internal things. - Dropped subscript chars for wear, this didn't really add anything and can be accomplished by specifying the --wear-chars explicitly. Also changed dbgblock.py to match, this mostly affects the --off/-n/--size flags. For example, these are all the same: ./scripts/dbgblock.py disk -B4096 --off=10 --size=5 ./scripts/dbgblock.py disk -B4096 --off=10 -n5 ./scripts/dbgblock.py disk -B4096 --off=10,15 ./scripts/dbgblock.py disk -B4096 -n10,15 ./scripts/dbgblock.py disk -B4096 0.10 -n5 Also also adopted block-device geometry argument across scripts, where the -B flag can optionally be a full <block_size>x<block_count> geometry: ./scripts/tracebd.py disk -B4096x256 Though this is mostly unused outside of tracebd.py right now. It will be useful for anything that formats littlefs (littlefs-fuse?) and allowing the format everywhere is a bit of a nice convenience.	2023-10-30 15:52:20 -05:00

Tweaked tracebd.py in a couple of ways, adopted bdgeom/--off/-n

- Tried to do the rescaling a bit better with truncating divisions, so
  there shouldn't be weird cross-pixel updates when things aren't well
  aligned.

- Adopted optional -B<block_size>x<block_count> flag for explicitly
  specifying the block-device geometry in a way that is compatible with
  other scripts. Should adopt this more places.

- Adopted optional <block>.<off> argument for start of range. This
  should match dbgblock.py.

- Adopted '-' for noop/zero-wear.

- Renamed a few internal things.

- Dropped subscript chars for wear, this didn't really add anything and
  can be accomplished by specifying the --wear-chars explicitly.

Also changed dbgblock.py to match, this mostly affects the --off/-n/--size
flags. For example, these are all the same:

  ./scripts/dbgblock.py disk -B4096 --off=10 --size=5
  ./scripts/dbgblock.py disk -B4096 --off=10 -n5
  ./scripts/dbgblock.py disk -B4096 --off=10,15
  ./scripts/dbgblock.py disk -B4096 -n10,15
  ./scripts/dbgblock.py disk -B4096 0.10 -n5

Also also adopted block-device geometry argument across scripts, where
the -B flag can optionally be a full <block_size>x<block_count> geometry:

  ./scripts/tracebd.py disk -B4096x256

Though this is mostly unused outside of tracebd.py right now. It will be
useful for anything that formats littlefs (littlefs-fuse?) and allowing
the format everywhere is a bit of a nice convenience.

Dropped the header from dbg scripts

I had never noticed xxd has no header until comparing its output against
dbgblock.py. Turns out these headers aren't really all that useful, and
even sometimes wrong in dbglfs.py.

Added dbgblock.py for quicker hex dumps

This script is basically the same as xxd, but with the other debug
script's block address format:

  $ ./scripts/dbgblock.py disk -B4096 1
  block 0x1, size 20
  off       data
  00000000: 00 00 00 00 00 03 00 08 6c 69 74 74 6c 65 66 73  ........littlefs
