IoT MCU Firmware Loader

Cross-target firmware loading and device provisioning tool for ARM Cortex-M devices.

About

The firmware loading tool fm_load.exe is "plug and load" and ready to program firmware binaries into internal flash on supported targets. This tool currently supports programming the MSP432, CC26XX and CC13XX MCUs from TI, the STM32L152 MCU from STMicro via ST-Link on Nucleo development boards, and the Nordic nRF52832 MCU through the XDS110 debug interface present on newer LaunchPad development platforms for CC26xx, CC13xx and MSP432. fm_load has been built and tested with Windows 10, and is code-signed by Firmware Modules Inc.

fm_load.exe is a packaged set of Python compiled code based on the pyOCD project and integrates the pyswd st-link access library.

Why did we make this tool? First off, it is command-line driven which allows automated build and test systems to be setup. Projects that are mature enough to require dev-ops will love that. Secondly, for TI targets, it's a heck of a lot smaller than Uniflash! Also, it contains a customized GDB server to facilitate automated unit test interaction with the targets. This feature is available with our IoT Firmware Cores.

Usage

fm_load.exe is intended to be executed in a console.

Without any command-line options, executing fm_load.exe will show the following console output if a supported development platform is connected (e.g. MSP-EXP432P401R LaunchPad). The actual connected device is reported at the Detecting target... phase. If no firmware binary image (.hex or .bin) is supplied nor any command-line argument, the message "No operation performed" is displayed and the program ends.

To select a specific board to connect to, use the -t option to specify a target like this: fm_load -t cc1310f128. In this case, each board is examined closely for a match and released if the detected target does not match the supplied target string.

Loading Firmware

Loading firmware onto a supported target device is as simple as adding the file name of the firmware binary image to load as a command-line argument as shown below (with only the desired target development board connected). When multiple supported target development boards are connected, the specific target must be set with the -t option.

In this instance a progress bar is displayed showing the status of firmware programming. When programming is completed, the target is reset and begins executing out of internal flash at address 0x0.

Release Notes

fm_load

Version 1.2.74

Adds support for the ST-Link V2/V2-1 debugger present on Nucleo development boards.
Adds support for the STM32L152RE MCU present on the Nucleo-L152RE development board. fm_load can be used to program binaries on the Nucleo-L152RE. This is somewhat redundant to the built-in mbed mass storage firmware loading capability (drag 'n drop) that Nucleo development boards offer, but it can load .hex files, which the mbed method cannot.

Version 1.2.68

Adds support for the Nordic Semiconductor nRF52832 Cortex-M4F MCU target. This target can be accessed through any XDS110 debug probe.
Adds factory reset option to disable access port protection on nRF52832 devices.
Adds soft reset option to initiate an MCU soft reset. This feature allows externally debugged targets without any reset control to be reset without power cycling.

Version 1.2.65

Executable is code-signed with Firmware Modules' globally recognized certificate.
Adds support for connecting to and programming CC26XX and CC13XX devices.
Adds support for selecting amongst multiple connected target development boards.
Supported targets
- MSP432P401x
- CC26xx
- CC13xx

Version 1.1.56

First public release.
Supported debuggers/programmers
- XDS110
Supported targets
- MSP432P401R
