Software Package Requirement
The original development tools are from Amazon FreeRTOS GitHub. To make it easier for non-developers to u pdate the firmware, Browan extracts the required parts and repackages them into browan_esptool.
Please refer to browan_esptool-v [X]. [Y] .tar.gz which attached in this document and copy it to your Linux ma chine.
$ ls -l -rw-rw-r– 1 vagrant vagrant 8896515 Jan 21 08:23 browan_esptool-v2.0.tar.gz
Extract the tarball using the following command:
$ tar -zxvf browan_esptool-v2.0.tar.gz $ ls -l drwxrwxr-x 4 vagrant vagrant 4096 Jan 21 08:21 browan_esptool-v2.0 -rw-rw-r– 1 vagrant vagrant 8896515 Jan 21 08:23 browan_esptool-v2.0.tar.gz

browan_esptool.sh is a script to invoke esptool commands esptool/ provided by Amazon FreeRTOS images/ includes the firmware images released by Browan. New firmware updates only need to update t
his folder. install_pkg.sh is a script to install the required packages requirements.txt is the python module require list for esptool
In Ubuntu 14.04 LTS, you need to install the following packages:

libssl-dev libffi-dev python python-pip python-setuptools python-serial python-pyparsing

And install the following packages using pip:

testresources setuptools pyserial>=3.0 * future>=0.15.2

MiniHub Pro uses the CP2102 chip as a USB-to-serial interface. Your system needs a correct driver.
Connect the MiniHub to the type-C breakout board and then connect it to your host Linux. Use the following c ommands to check whether the system automatically mounts the CP2012 driver.

$ lsmod | grep cp210x

cp210x

28672 0

usbserial

49152 2 pl2303,cp210x

If UART does not work well, download the “CP210x USB to UART Bridge VCP Drivers” from Silicon Labs o fficial website, and install the device driver following the guideline.
https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge- vcp-drivers
If not, you need to install the following packages:

linux-modules-extra-uname -r

If you need to monitor the MiniHub Pro terminal screen on Linux, you would need to add the user to the dialo ut group.

$ sudo usermod -a -G dialout $USER

The above installation and settings operations can be completed automatically using the install_pkg.sh provided by Browan. To apply the installed drivers, please restart the system after executing install_pkg.sh.

$ cd browan_esptool-v2.0/
$ ls -l total 20 -rwxrwxr-x 1 andrew andrew 1081 Jan 21 16:21 browan_esptool.sh drwxrwxr-x 6 andrew andrew 4096 Jan 21 16:19 esptool drwxrwxr-x 2 andrew andrew 4096 Apr 16 11:44 images -rwxrwxr-x 1 andrew andrew 620 Jan 21 15:59 install_pkg.sh -rw-rw-r– 1 andrew andrew 434 Jan 21 14:37 requirements.txt

Erase Flash and Upgrade Firmware
If your system installed correct CP2012 driver, when MiniHub Pro connects to the host Linux through USB, Li nux should automatically generate the corresponding /dev/ttyUSB? character-device. You can use the following command to verify:
$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 002: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySm artUSB light

$ ls -l /dev/ttyUSB* crw-rw—- 1 root dialout 188, 0 Jan 21 09:03 /dev/ttyUSB0
You can use browan_esptool.sh to do flash erasing and programming operations. Please note that before executi ng an erase or program, you need to power off the device, then hold down the SETUP button and reconnect the USB power supply. The device will switch to flash download mode before executing browan_esptool.sh
