您需要在環境中設定 PICO_SDK_PATH ，或使用-DPICO_SDK_PATH=/path/to/pico-sdk將其傳遞給 cmake 。要使用簽名或雜湊等功能，您需要確保 SDK 中的 mbedtls 子模組已簽出 - 這可以透過從 SDK 目錄運行它來完成。
git 子模組更新 --init lib/mbedtls
您還需要安裝libusb-1.0 。
使用您最喜歡的打包工具來安裝依賴項。例如，在 Ubuntu 上：
sudo apt install build-essential pkg-config libusb-1.0-0-dev cmake
然後像普通的 CMake 專案一樣建置：
mkdir buildcd buildcmake ..make
在 Linux 上，您可以新增 udev 規則以便無需 sudo 即可執行 picotool：
sudo cp udev/99-picotool.rules /etc/udev/rules.d/
從這裡下載 libUSB https://libusb.info/
將 LIBUSB_ROOT 環境變數設定為安裝目錄。
mkdir buildcd buildcmake -G "NMake Makefiles" ..nmake
從這裡下載 libUSB https://libusb.info/
將 LIBUSB_ROOT 環境變數設定為安裝目錄。
mkdir buildcd buildcmake ..make
無需單獨下載 libusb 或設定LIBUSB_ROOT 。
pacman -S $MINGW_PACKAGE_PREFIX-{toolchain,cmake,libusb}mkdir buildcd buildcmake .. -DCMAKE_INSTALL_PREFIX=$MINGW_PREFIXcmake --build .Raspberry Pi Pico SDK (pico-sdk) 版本 2.0.0 及更高版本使用picotool執行先前由 SDK 中的elf2uf2工具處理的 ELF 到 UF2 轉換。 SDK 也使用picotool對二進位檔案進行雜湊和簽署。
雖然 SDK 可以為每個專案單獨下載 picotool，但如果您有多個專案或建置配置，最好在本機安裝picotool的單一副本。 這可以透過make install或cmake --install . ; SDK 將預設使用此安裝版本。
或者，您可以透過以下方式安裝到自訂路徑：
cmake -DCMAKE_INSTALL_PREFIX=$MY_INSTALL_DIR -DPICOTOOL_FLAT_INSTALL=1 ..
為了讓 SDK 在此自訂路徑中找到picotool ，您需要在專案中設定picotool_DIR變量，方法是設定picotool_DIR環境變數、將-Dpicotool_DIR=$MY_INSTALL_DIR/picotool傳遞至cmake指令，或新增set(picotool_DIR $MY_INSTALL_DIR/picotool)到您的 CMakeLists.txt 檔案。
picotool是一個用於處理 RP2040/RP2350 二進位檔案並在 RP2040/RP2350 裝置處於 BOOTSEL 模式時與它們互動的工具。 （從picotool版本 1.1 開始，也可以與未處於 BOOTSEL 模式但使用 Raspberry Pi Pico SDK 的 USB stdio 支援的裝置進行交互，方法是使用picotool的-f參數）。

請注意，不作用於檔案的指令需要連接處於 BOOTSEL 模式的裝置。
SDK 中支援二進位訊息，可以輕鬆儲存picotool可以找到的緊湊資訊（請參閱下面的二進位資訊部分）。 info 命令用於讀取此資訊。
這些資訊可以從 BOOTSEL 模式下的一個或多個連接的裝置讀取，也可以從檔案讀取。該檔案可以是 ELF、UF2 或 BIN 檔案。

RPI-RP2 drive mountedotp指令用於與 RP2350 OTP 記憶體互動。它們在 RP2040 設備上不可用，因為 RP2040 沒有 OTP。
請注意，OTP 記憶體是一次性可編程的，這意味著一旦一位從 0 更改為 1，就無法改回原來的狀態。因此，使用這些命令時應小心謹慎，因為它們可能會導致 RP2350 設備變磚。例如，如果您設定了 SECURE_BOOT_ENABLE 但沒有設定啟動鍵，並停用 PICOBOOT 接口，那麼您的裝置將無法使用。
對於list 、 set 、 get和load指令，您可以在 JSON 檔案中定義自己的 OTP 佈局，並使用-i參數傳遞該佈局。解析時這些行將會加入到預設行。
$ picotool help otp
OTP:
Commands related to the RP2350 OTP (One-Time-Programmable) Memory
SYNOPSIS:
picotool otp list [-p] [-n] [-i <filename>] [<selector>..]
picotool otp get [-c <copies>] [-r] [-e] [-n] [-i <filename>] [device-selection] [-z] [<selector>..]
picotool otp set [-c <copies>] [-r] [-e] [-i <filename>] [-z] <selector> <value> [device-selection]
picotool otp load [-r] [-e] [-s <row>] [-i <filename>] <filename> [-t <type>] [device-selection]
picotool otp dump [-r] [-e] [device-selection]
picotool otp permissions <filename> [-t <type>] [--led <pin>] [--hash] [--sign] [<key>] [-t <type>] [device-selection]
picotool otp white-label -s <row> <filename> [-t <type>] [device-selection]
SUB COMMANDS:
list List matching known registers/fields
get Get the value of one or more OTP registers/fields (RP2350 only)
set Set the value of an OTP row/field (RP2350 only)
load Load the row range stored in a file into OTP and verify. Data is 2 bytes/row for ECC, 4 bytes/row for raw. (RP2350 only)
dump Dump entire OTP (RP2350 only)
permissions Set the OTP access permissions (RP2350 only)
white-label Set the white labelling values in OTP (RP2350 only)這些命令將設定/取得 OTP 的特定行。預設情況下，它們將寫入/讀取所有冗餘行，但這可以使用-c參數覆蓋
此命令允許將一系列 OTP 行載入到裝置上。來源可以是二進位文件，也可以是 JSON 文件，例如picotool sign輸出的文件。例如，如果您希望對二進位檔案進行簽名，然後使用它來測試安全啟動，則可以執行以下命令集：
$ picotool sign hello_world.elf hello_world.signed.elf private.pem otp.json
$ picotool load hello_world.signed.elf
$ picotool otp load otp.json
$ picotool reboot此命令允許 OTP 白標，這會設定裝置在 BOOTSEL 模式下使用的 USB 設定。這可以從 JSON 檔案進行配置，範例位於 Sample-wl.json 中。
