leaps_fw_update_xfer


Should be called repeatedly after leaps_fw_update_start to transfer firmware data chunks until all the firmware is transferred. Returns status “ok” if the data chunk was processed successfully or an error. The error is indicated by status other than “ok”. The reasons for failed firmware update are:

  • internal error

  • invalid parameter - e.g. data chunk with zero length, or corrupted data

  • not permitted - not started yet or the whole update process has failed

  • checksum error - corrupted data received or the checksum value provided at the start of the update by the leaps_fw_update_start and the checksum calculated by the module at the end does not match

The size and the offset of the data that has been already processed byd q the firmware update procedure so far are returned as a response on each call to leaps_fw_update_xfer until the update finishes.


Input
  • offset: ? 32-bit integer ? (* Offset of the total firmware data.*)

  • data: ? from 4 up to 240 bytes ? (Firmware data chunk.)

Output
  • Status Code

  • offset: ? 32-bit integer ? (Offset of data that need to be written next by leaps_fw_update_xfer)

  • size: ? 32-bit integer ? (Size of firmware data chunk that need to be written by leaps_fw_update_xfer)
