PICOTOOL-OTP-SET(1)

🎀 NAME 🎀

picotool-otp-set — bestie, this is the little picotool subcommand that sets the value of an OTP row/field. That's it, that's the whole personality. It's part of the picotool User Commands lineup and it is so specific and so powerful. 💅

---

✨ SYNOPSIS ✨

picotool otp set [-c <copies>] [-r] [-e] [-s] [-i <filename>] [-z]
<selector> <value> [device-selection]

---

💖 OPTIONS 💖

🔥 Redundancy/Error Correction Overrides

okay so this is the group of flags that mess with how many copies and what kind of bits you're writing ✨

• -c <copies> — write multiple redundant values. That's <copies>-many copies, no cap, iconic.
• -r, --raw — set raw 24-bit values. Yeah, 24 bits, exactly as much as a row holds, don't ask questions.
• -e, --ecc — use error correction. Let the hardware be the main character for once.
• -s, --set-bits — set bits only. Bits that are already 0 stay 0, we are not clearing anything, we are just ✨adding✨.
• -i <filename> — include an extra otp definition from <filename>. Extra definitions? In my config? It's more likely than you think. 🦋
• <value> — the value to set. The whole point. The moment. 👑

🔍 Row/Field Selection

• -z, --fuzzy — allow fuzzy name searches in the selector instead of exact match. Lowkey a lifesaver when you half-remember the name, highkey a way to select the wrong thing, be careful bestie. 😭
• <selector> — the row/field selector. It can select a whole row:
  • ROW_NAME — select a whole row by name.
  • ROW_NUMBER — select a whole row by number.
  • PAGE:PAGE_ROW_NUMBER — select a whole row by page, and the number within that page.
• ... or it can select a single field / a subset of a row. (Where ROW_SEL is one of the row selectors above, obviously 💜)
  • ROW_SEL.FIELD_NAME — select a field within a row, by name.
  • ROW_SEL.n-m — select a range of bits within a row.
  • ROW_SEL.n — select a single bit within a row.
  • .FIELD_NAME — select any row's field by name. No row specified, we're just out here vibing, matching a field name across the board.

🫶 TARGET SELECTION 🫶

Target device selection

Not sure which little board is which? Say less. These narrow it down 👇

• --bus <bus> — filter devices by USB bus number.
• --address <addr> — filter devices by USB device address.
• --vid <vid> — filter by vendor id.
• --pid <pid> — filter by product id.
• --ser <ser> — filter by serial number.
• -f, --force — force a device that is not in BOOTSEL mode but is running compatible code to reset, so the command can actually execute. After the command runs (unless the command itself is a reboot) the device gets rebooted back to application mode. It's giving "brb, gotta reset you for a sec." 🌈
• -F, --force-no-reboot — same forcing deal: a device not in BOOTSEL mode but running compatible code gets reset so the command can execute. After the command (unless the command itself is a reboot) the device is left connected and accessible to picotool, but with no USB drive mounted. So like... present but not presenting. 💀

Heads up bestie: both -f and -F reset your device, and the reboot-back behaviour is the difference between them. Pick with intention. 🎀
