Starting with Hardware Version 4.3 of the can bus loadcell, EEPROM write protection got introduced. So to make any changes to the EEPROMS content, CPU PIN 2_2 needs to be pulled down to gnd (0).
To successfully flash a firmware using BHT Scanner application, you need to manually disable write protection of the cell by sending a write command 0xF7 with value 0x00 to the cell and omit rebooting the cell. On reboot - the write protection will be reactivated automatically!
CAN-ID:
0x18EF(DESTINATION_ADDRESS)(SOURCE_ADDRESS)PGN: 61184 Payload: 0x02, 0xF7, 0x00 --> Deactivate write protection or Payload: 0x02, 0xF7, 0x01 --> Activate write protection
- supporting write protect
- CAN-EN enabled (needs CAN-EN high for addressing / boot)
- debug enabled (Does not check CRC of HEX-File, Firmware can be flashed using ulink2)

All versions of the Bootloader ~.hex files must be flashed using either ulink2 directly or using FlashMagic.
