Preparing for flashing§

1. Download and unpack the firmware archive The “Download” button is in the panel under the device name.
2. Prepare a UART adapter or a programmer On this model the installation is possible only with the device disassembled.

Installing from stock firmware§

1. Extracting the EEPROM Back up the flash memory with a programmer and extract the EEPROM with the “Extract EEPROM” tool. Or replace the bootloader with Breed via UART and save the EEPROM from there.

2. Preparing the EEPROM First move the calibration, then set the MAC address in the resulting file. The result is your EEPROM.

3. Flashing In the second item of the second tab, choose the RC04/RA75_4.2.6_FULL.bin firmware, clear the last 2 checkboxes and confirm the upload.

   

4. Restoring the EEPROM After the installation, enter Breed again by holding Reset and restore the EEPROM from step 2.

   

After the reboot the device starts.

Updating the firmware§

Reverting to stock firmware§
