Development Options
The UCM development options can greatly simplify the process of building a product or prototype using the UC5550. Options include a development board and displays which can get you programming in minutes.
Tip
We are assuming you are using the UCM Development Board for all instructions provided.
Loading Bootloader v2
- Download the UC5550 bootloader here.
- Connect your device to the USB client port.
- Put the board in DFU mode: Hold the SYS A pin low and press/release the reset button. Wait for a second then release SYS A. Windows Device Manager will now show "STM Device in DFU Mode" under the 'Universal Serial Bus controller' TAB.
- This is a DFU file, upload it like you would any other DFU file. See STMicroelectronics documentation for details.
Loading the Firmware
- Activate the bootloader, hold the LDR0 signal low while resetting the board.
- Open FEZ Config tool and follow the instructions.
Start Coding
Now that you have installed the bootloader and firmware on the UC5550, you can setup your host computer and start programming. Go to the NETMF Getting Started page for instructions.
Schematic
The schematic for the UC5550 can be found here.
Customization
We also offer customized, non-stock versions of our SoMs. Many options are available, such as various sizes of external QSPI flash. Please contact us for details. We will always do our best to provide you with a module to fit your exact needs.
