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.
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.
Note
For more information about supported communication interface check the blhost application documentation.
