picotool manages Raspberry Pi Pico and RP2040 devices. It loads firmware, reads device info, and controls boot mode.
Device info shows chip details and running program. Binary info displays embedded metadata.
Loading writes firmware to flash. UF2 and ELF formats are supported.
Save extracts flash contents for backup. The entire flash or specific regions can be dumped.
Verification compares device contents to a file. Useful for confirming successful programming.
