Updating the Firmware of NT Modules
All NT Modules can be updated with a new firmware using the procedure below.
Comment: Updating implies that the module has a NT firmware running. If the module has never been flashed with a NT firmware before, or runs a different firmware, you must do first a "First Time Flashing". Please inspect the related wiki pages.
Updating Procedure
1. You need a standard USB-TTL adapter (FTDI, CP2102, ..., not PL2303). Ensure that it is working (drivers installed, etc.).
Comment: It's the same adapter you use for flashing the STorM32 controller board.
2. Connect the USB-TTL adapter to the NT bus connector.
- "GND" to "G"
- "VCC" to "5V"
- "TX-" to "Rx"
- "RX-" to "Tx"
3. Connect the USB-TTL adapter to the computer and open the GUI.
4. Go to the [GUI:Flash Firmware] tab as seen below. Choose the firmware in the [GUI:STorM32-BGC board] combo box field, or via the [GUI:Selected Firmware Hex File] text field. Select "System Bootloader @ UART1" in the [GUI:STM32 Programmer] field, and the [GUI:Com Port] associated with your USB-TTL adapter. Ensure that the "Use NT bootloader mode" check box is checked.
5. Hit the [GUI:Flash Firmware] button. A DOS box will open, and the firmware will be flashed.
