The following tools may be copy/pasted into the rp2040 console w/<CTRL>-e, or they may be run on another computer against /tmp/rp2040.flash_dump assuming that file was previously saved from an rp2040 device.

• mocked_Maix_utils.py: ensures that utils.flash_read() is available, because tools here need it.

• hash_flash.py: returns the sha256 hash of bytes in flash.

• crc32_flash.py: returns the crc32 checksum of bytes in flash.

• hashcrc_flash.py: returns the sha256 hash and the crc32 checksum of bytes in flash.

• all_bytes_are.py: returns true if bytes in flash are the same as the one passed in.

• hex_dump.py: a kludgy-yet-versatile implementation of hex_dump for visually inspecting bytes in flash.

• uf2parse.py: a commandline parser of firmware.uf2 files for validity, size, checksums and/or flashdump.
