Wait for completion

ESP32

  1. Take ESP32 flash download tool from this location: http:https://www.espressif.com/en/support/download/other-tools
    You might also need to install:

  1. Download an appropriate version of SoftRF firmware from this location and unzip the archive ;

  2. Select COM port, enter partition files and addresses, select options ;

    Here is an example:

  1. Press START button and wait for completion.

For some boards you may need to push BOOT button in order to activate flash download mode.
"Stock" modules may also require to apply full flash memory erase (use ERASE UI "button") prior to first flashing with SoftRF's firmware.
One may need to reduce BAUD rate down to 115200 bps.


CubeCell

  1. Take CubeCellflash for Windows (Linux and MacOS variants are also available there) download tool from this location: https://resource.heltec.cn/download/
    You might also need to install a driver for the CP210X USB to UART bridge from Silicon Labs prior to first use of the CubeCellflash tool ;
  2. Download an appropriate version of SoftRF firmware from this location and unzip the archive ;

  1. Use Windows command line tool to execute firmware flashing procedure as follows:


nRF52840

The T-Echo board typically comes with factory pre-installed Adafruit_nRF52_Bootloader.
The Bootloader is capable to self-program an application firmware into the device. In order to simplify the firmware transfer, the bootloader emulates a "USB Mass Storage" interface.

  1. Download an appropriate version of SoftRF firmware from this location ;

  2. Connect the SoftRF Badge Edition device to your PC by means of a USB cable (Type-A <-> Type-C) ;

  3. Double click (within 0.5 seconds) onto the SoftRF device RESET button. A virtual disk with NRF52BOOT (or TECHOBOOT) label should appear in your "File manager" afterwards.

  4. Drag the downloaded firmware file by your pointing device (mouse, trackball,...) , then drop it into NRF52BOOT (or TECHOBOOT) disk. Wait until the file transfer is complete.



LPC4320

For Linux and Mac OS X users, you will need a few tools installed on your computer before you begin:

  • dfu-util 0.8 or newer - Used to load and run the stock HackRF One firmware from RAM. dfu-util 0.8 is recommended, as it is the most extensively tested with the HackRF One hardware and build software.
  • hackrf - All you need is the host tools, specifically, hackrf_spiflash.

Backup of factory firmware

$ hackrf_spiflash -v -r HackRF_One_factory_firmware.bin
Reading 256 bytes from 0x000000.
Reading 256 bytes from 0x000100.

< ... skipped ... >

$ ls -la HackRF_One_factory_firmware.bin
-rw-r--r-- 1 pi pi 1048576 Nov  4 10:18 HackRF_One_factory_firmware.bin

Flashing

  1. Download an appropriate version of SoftRF firmware from this location ;
  2. Plug the HackRF One into a PC USB slot while holding down DFU button (the button closer to antenna jack). Release the DFU button, then execute:
$ dfu-util -D hackrf_one_usb.dfu --reset
$ hackrf_spiflash -v -w SoftRF-firmware-v1.1-LPC4320.bin

Restore of HackRF One firmware

Plug the HackRF One into a PC USB slot while holding down DFU button (the button closer to antenna jack). Release the DFU button, then execute:

$ dfu-util -D hackrf_one_usb.dfu --reset
$ hackrf_spiflash -v -w HackRF_One_factory_firmware.bin

ASR6601

  1. Download an appropriate version of SoftRF firmware from this location ;
  2. Take a copy of tremo_loader.py script from ASR SDK ;
  3. Connect an appropriate USB-Serial adapter to ASR6601 MCU pins as follows:
Adapter MCU
GND GND
3V3 VCC
TX GPIO16
RX GPIO17
DTR 2 GPIO2
RTS RESET

2 - certain USB-Serial adapters may require to invert DTR signal either in hardware or in the Python script.

  1. Plug the USB-Serial adapter into spare USB slot of your PC ;
  2. Use the loader tool to read the serial number of the MCU. This is a safety action to make sure that all the connections are good ;
$ python tremo_loader.py --port /dev/ttyUSB0 read_sn
Connecting...
Connected
The SN is: 0c15458cc5fb3201
  1. Write the SoftRF firmware binary into flash memory of the ASR6601.
$ python tremo_loader.py --port /dev/ttyUSB0 flash 0x08000000 SoftRF-firmware-v1.1-ASR6601.bin
Connecting...

RP2040

Every RAK11310 WisBlock Core module has built-in (ROM) bootloader.
The bootloader is capable to self-program an application firmware into the device. In order to simplify the firmware transfer, the bootloader emulates a "USB Mass Storage" interface.

  1. Download an appropriate version of SoftRF firmware from this location ;

  2. Plug RAK11310 WisBlock Core module into RAK5005-O WisBlock Base ;

  3. Connect the RAK5005-O to your PC by means of a USB cable (Type-A <-> micro Type-B) ;

  4. Press and keep holding BOOT button of RAK11310 Core module ;

  5. Press and release RESET button on RAK5005-O Base ;

  6. Release BOOT button of RAK11310 module. A virtual disk with RPI-RP2 label should appear in your "File manager" afterwards ;
