SetUp

To flash the MPCam’s eMMc, you will need:

Linux host station (tested with Ubuntu 18.04)
Release package (zip) containing the eMMC image (see: Downloads)
STM32CubeProgrammer:
- download from: STM32CubeProg - STMicroelectronics
USB-A Male to Male adapter/cable (Google search)
Optional: ST/Link-V3 (+10-pin connector)
- ST/Link can be used to access the serial terminal

Quick Steps

set S201 switches to DFU:
plug in the USB-A cable to the MPCAM and host station
power the MPCam
open a terminal in the working directory where the release was unzipped, then run:
1. check: STM32_Programmer_CLI -l
2. flash: STM32_Programmer_CLI -c port=usb1 -w SIANA-mpcam-eMMC-*.tsv
  1. notes:
    1. USB flashing takes a while…
    2. best to not use a USB hub => direct to host station
on completion:
1. unpower the board
2. remove the USB cable
3. set the S201 switches to eMMC boot:
4. power the MPCam => it should boot into Linux!

Detailed Steps

Get the release package

download the release zip, ex: SIANA-MPCam-RevB-eMMC-01.04.zip
unzip the package in a working directory of your choice, for example:
- ~/development/MPCam/RevB/eMMc/1.04/
open a terminal in the working directory

Boot into DFU mode

With the MPCam unplugged, both USB & power:

set the switches (S201) to DFU mode:
plug in the USB-A cable from host to MPCam
plug in power to the MPCam (red power LED turns on)
in the terminal, run: STM32_Programmer_CLI -l
- note:
  - STM32_Programmer_CLI is expected to be in your PATH, if not, run with fully qualified path, ex:
    Assuming that the STM32CubeProgrammer is installed in ~/opt/
    ~/opt/STM32CubeProgrammer/STM32CubeProgrammer-2.7/bin/STM32_Programmer_CLI

Flash image in the eMMC

With the MPCam booted in DFU mode:

in the terminal, run: STM32_Programmer_CLI -c port=usb1 -w SIANA-mpcam-eMMC-*.tsv

The STM32CubeProgrammer should now go through the flashing for each of the partitions defined in the *.tsv file. Note: it’ll take several minutes to flash the 4GB eMMC.

on success, the STM32CubeProgrammer should report: Flashing service completed successfully
- on failure, retry with another USB cable and ensure that no USB Hub is between MPCam and host.

Boot from eMMC

Once the eMMC is successfully flashed:

unplug the USB-A and remove power from the MPCam
set the switches (S201) to eMMC mode:
plug in the power to the MPCam (red LED tuns on)
MPCam now boots from eMMC…
- optional: you can use the ST/Link-V3 to monitor the serial terminal.
on completion, the blue status LED will blink to show kernel activity.
