Flashing OlliW's NT Modules

On all "OlliW" NT modules the BOOT0 pin is exposed as a solder jumper, and each module can thus be first-time flashed using a standard USB-TTL adapter. Most modules also have the SWD pins exposed, which allows a first-time flashing via a ST-Link adapter. Both flashing methods are fully supported by the GUI. Any subsequent flashing (updating) can be performed using the simpler procedures described in Updating the Firmware of NT Modules.

First-Time Flashing Using a USB-TTL Adapter

1. You will need a standard USB-TTL adapter (see FAQ: Which USB-TTL adapter should I use?). Ensure that it is working (drivers installed, etc.).

2. Connect the USB-TTL adapter to the NT bus pins on the NT bus connector. Do not yet power the NT module.

3. Find the BOOT0 solder jumper on the NT module and close it.

4. Now power up the NT module, e.g., by connecting the NT bus connector's VCC pin to the 3.3 V or 5 V pin (either is fine) on the USB-TTL adapter.

5. In the STorM32 GUI go to the [GUI:Flash Firmware] tab and choose your settings.

6. Select the correct NT module and the desired firmware version in the respective combo boxes [Board] and [Firmware Version].

7. Select "System Bootloader @ UART1" in the [STM32 Programmer] field.

8. In the [Com Port] field select the COM port which your USB-TTL adapter is connected to.

9. Finally, hit the [Flash Firmware] button.

10. Now a black window (DOS console) should open and run the flash loader program. Wait until it is finished (takes some seconds).

11. Open the BOOT0 solder jumper again. The NT module is now ready for usage.

First-Time Flashing Using SWD

1. You will need a ST-Link V2 Programmer or similar. Ensure that it is working (drivers installed, etc.).

2. Connect the programmer to the SWD pins on the NT module.

3. In the GUI go to the [GUI:Flash Firmware] tab and choose your settings. It should look something like this:

4. Push the [Flash Firmware] button.

5. Now a black window (DOS console) should open and run the ST-Link loader program, as shown in the screenshot. Wait until it's finished (takes some seconds). The NT module will be reset and start running.

Updating Firmware

For updating the NT firmware you may again use the methods described before, but preferably the "canonical" procedure described in Updating the Firmware of NT Modules.
