Procedure to Flash Alpha device

Prerequisites 

 Before starting, ensure you have the following: 

 

 Download Flashing tool and latest firmware here -> Flashing Tool.zip 

 Windows laptop/pc (recommended) 

 microUSB cable 

 Cytron USB-UART Converter UC00C (shown below) 

 

 

 

 Flashing Procedure 

 

 The programmer pins must be exposed via male headers at a 2.54mm pitch 

 

 Pin Order: Ensure the pins are arranged in this specific sequence : 

 

 

 

 DTR 

 

 

 RX 

 

 

 TX 

 

 

 3.3V 

 

 

 RTS 

 

 

 GND 

 

 

 

 Insert the programmer into the flashing female port of the board, matching the pin names except for TX and RX , which are typically swapped . 

 Tilt the programmer at an angle to ensure a solid electrical connection with the port . 

 Open the downloaded Espressif Flash Download Tool (Flashing Tool -> flash_download_tool_3.9.4) . 

 Upon opening the software, select the following settings : 

 

 Chip Type: ESP32-C3 

 WorkMode: Develop (for single board) or Factory (for multiple boards) 

 LoadMode: UART 

 

 

 Set the file paths at the following addresses: 

 

 

 

 File Name 

 Memory Address (Offset) 

 

 

 

 

 bootloader_v2.bin 

 0x0000 

 

 

 partitions_v2.bin 

 0x8000 

 

 

 boot_app0_v2.bin 

 0xe000 

 

 

 AlphaX_BASE_x.x.x.bin   

 0x10000 

 

 

 

 The files can be located at: Flashing Tool -> Firmware -> (select device model eg: Alpha1) 

 PLEASE USE THE LATEST FILES PROVIDED IN THE ATTACHED FILE ABOVE  

 

 Configure the SPI Flash Config section as follows : 

 

 SPI SPEED: 80MHz 

 SPI MODE: DIO 

 Baud Rate: 921600 

 

 

 The flashing process: 

 

 For Single Boards: 

 

 Select the appropriate COM port 

 Click "START" to begin . 

 Monitor the progress bar as the upload proceeds . 

 

 

 For Multiple Boards (Factory Mode) 

 

 Uncheck "LockSettings" to modify configurations . 

 Assign the correct COM port for each attached programmer . 

 Re-check "LockSettings" to secure the configuration . 

 Click "START ALL" to flash all boards simultaneously . 

 NOTE: It is recommended to ERASE the board first before re-flashing it. This can be done by pressing ERASE in the flashing tool before flashing. 

 

 

 

 

 

 

 

 

 Verification 

 Once the upload is complete, look for the following indicator on the board: 

 

 The blue, green, and yellow LEDs will flash twice to signify a successful firmware upload 

 The blue led will start blinking continuously indicating that device is ready to be setup and configured
