The host may use any port ID that is valid for the corresponding board
when calling the flash ROM write command. It is not necessary to open
the port used before.
The size of the download data block is limited to
EKF_MU_DOWNLOAD_BUFFER_SIZE minus the size of the structure
EKF_DOWNLOAD_PARAMS. Therefore it is necessary to split and
download the firmware in several blocks.
After all blocks of the new firmware binary are written to the flash ROMs
a board hardware reset must be supplied to start the new firmware.
See section “
EKF_DOWNLOAD_PARAMS
” for a description of the
download parameter structure.
