sb-update is a program which allows you to reflash, verify, and query the version of sensor board firmware. It works with either the MSB or LSB (provided that the bootloader is installed on them). sb-update accepts Intel HEX format firmware files. Note: The reflash and verify commands switch the sensor board to its bootloader mode. To switch back to regular operation, you must either power-cycle the board or issue the get-version command.

If you'd like to understand how sb-update works behind the scenes, see the bootloader protocol details.

usage

Typical Usage

sb-update /dev/ttyS0 get-version
sb-update /dev/ttyS0 reflash firmware.hex

reflash <firmware.hex>    reflashes the firmware on the sensor board with the specified hex file
verify <firmware.hex>     verifies that the firmware on the sensor board matches the specified hex file
