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.
-
