Deploy the MicroPython firmware to the Metro M7 board. + +### 1.1 Deploy the firmware using the serial bootloader. + +For initial deployment of the firmware a few preparation steps are required, which +have to be done once. + +1. Get the files ufconv.py and uf2families.json from the micropython/tools directory, +e.g. at https://github.com/micropython/micropython/tree/master/tools. + +2. Get the NXP program sdphost for your operating system, e.g. from +https://github.com/adafruit/tinyuf2/tree/master/ports/mimxrt10xx/sdphost. +You can also get them from the NXP web sites. + +3. Get the UF2 boot-loader package https://github.com/adafruit/tinyuf2/releases/download/0.9.0/tinyuf2-imxrt1010_evk-0.9.0.zip +and extract the file tinyuf2-imxrt1010_evk-0.9.0.bin. + +Now you have all files at hand that you will need for updating. + +1. Get the firmware you want to upload from the MicroPython download page. + +2. Set the two BOOTSEL DIP switches to the 1/0 position, which is the opposite position of the normal use mode. + +3. Push the reset button. + +4.

Just add a short wait before the 3rd command to let the drive connect. + +5. Once the upload is finished, set the BOOTSEL DIP switches back to the 0/1 position and push reset. + +Using sudo is Linux specific.

Appropriate tools are Segger JFlash Lite and +the Segger Edu Mini adapter. Just use the firmware.hex file for loading, which will be loaded at the +proper address. + + +## 2. Deploy the WiFi firmware. + +The NINA firmware in the NINA module has to be updated for use with MicroPython. That can be done +using MicroPython and two small Python scripts. + +The firmware binaries are available at +https://github.com/micropython/micropython-lib/tree/master/micropython/espflash +or https://github.com/robert-hh/Shared-Stuff. For the Metro M7 board, the +NINA_FW_v1.5.0_Airlift.bin file is needed. + +For firmware upload, the following connections to the WiFi module are required: + +- Pin Reset (as above) +- Pin GPIO0 +- UART RX +- UART TX + +The GPIO pins and UART device id varies between boards. At the Adafruit Metro M7 board, +the UART is UART(1), and the Pin names for reset and GPIO0 are ESP_RESET and ESP_GPIO0. +The firmware can be uploaded, using the espflash.py module, a short script +using espflash.py and mpremote. espflash.py is available at +https://github.com/micropython/micropython-lib/tree/master/micropython/espflash. +This place also holds the example script. + +``` +import espflash +from machine import Pin +from machine import UART +import sys +sys.path.append("/flash") + +reset = Pin("ESP_RESET", Pin.OUT) +gpio0 = Pin("ESP_GPIO0", Pin.OUT) +uart = UART(0, 115200, timeout=350) + +md5sum = b"b0b9ab23da820a469e597c41364acb3a" +path = "/remote/NINA_FW_v1.5.0_Airlift.bin" + +esp = espflash.ESPFlash(reset, gpio0, uart) +# Enter bootloader download mode, at 115200 +esp.bootloader() +# Can now change to higher/lower baud rate +esp.set_baudrate(921600) +# Must call this first before any flash functions. +esp.flash_attach() +# Read flash size +size = esp.flash_read_size() +# Configure flash parameters. +esp.flash_config(size) +# Write firmware image from internal storage. +esp.flash_write_file(path) +# Compares file and flash MD5 checksum. +esp.flash_verify_file(path, md5sum) +# Resets the ESP32 chip. +esp.reboot() +``` + +The script shows the set-up for the Metro M7 board. +The md5sum is the one of the WiFi firmware. It may change and +can be recalculated using e.g. the Linux `md5sum` command. It is used to +verify the firmware upload. To upload the firmware, place the firmware +and the above script (let's call it ninaflash.py) into the same directory +on your PC, and run the command: +``` +mpremote connect <port> mount . run ninaflash.py +``` +After a while, the upload will start.
