This user’s guide describes how to interface with the MCU bootloader to provisioned chip using nxpdevhsm application.
The nxpdevhsm application is a command-line utility used on the host computer to use device HSM process to get provisioning SB3.
spsdk.apps.nxpdevhsm:main
The nxpdevhsm application is using blhost application and all supported communication interfaces that blhost offers(UART, USB, LPCUSBSIO[IC, SPI])
blhost could be connected to MCU Bootloader over USB HID.
USB device identification in SPSDK
blhost could be connected to MCU bootloader over UART.
UART device identification in SPSDK
LPCUSBSIO - LPC USB Serial I/O(LPCUSBSIO), a firmware built in LPC Link2. The LPCUSBSIO acts as a bus translator, and establishes connection with blhost over USB-HID, and the MCU bootloader device over I2C and SPI.
For more information about supported communication interface check the blhost application documentation.
nxpdevhsm consist of a set of sub-commands followed by options and arguments. The options and the sub-command are separated with a ‘--’.
nxpdevhsm [options] -- [sub-command]The "help" guide of nxpdevhsm lists all of the options and sub-commands supported by the nxpdevhsm utility.
