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 first do a "First Time Flashing". Please consult the respective wiki pages.
Updating Procedure
1. You need a USB-TTL adapter with FTDI chip set, or properly configured CP2102 (not PL2303). Ensure that it is working (drivers installed, etc.).
Comment: To avoid confusion some explanation: For flashing the main STorM32 controller board USB adapters with both FTDI and CP2102 chip sets can be used without issues, while for flashing NT modules only FTDI adapters work out of the box. CP2102 adapters need some configuration to handle the high baudrate of the NT bus, see How to configure CP2102 USB adapters for high baud rates. USB adapters with PL2303 chips NEVER work since they don't provide TTL levels.
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 [Flash Firmware] tab as seen below. Choose the firmware in the [STorM32-BGC board] combo box field, or via the [Selected Firmware Hex File] text field. Select "System Bootloader @ UART1" in the [STM32 Programmer] field, and the [Com Port] associated with your USB-TTL adapter. Ensure that the "Use NT boot mode" check box is checked.
5. Hit the [Flash Firmware] button. A DOS box will open, and the firmware will be flashed.
