func (*Context) APGetVersion ¶

func (c *Context) APGetVersion() (update.FWVersion, error)

func (*Context) CRCCheck ¶

func (c *Context) CRCCheck(start, length uint32, crc uint16) (uint16, error)

CRCCheck() WILL ERASE THE FIRMWARE IF THE PASSED-IN 'crc' VALUE IS INCORRECT

The correct 'crc' value is derived from data received and a secret string stored in the IAP code. In the case of a firmware update, if the following sequence is followed, then the correct 'crc' value is returned by (*update.Update).GetCRCValue():

• Erase version string
• Erase firmware region
• Write encoded firmware data from (*update.Update).GetFWBlob(...).RawData() in 52-byte chunks, via WriteData()
• Call CRCCheck() with 'crc' = (*update.Update).GetCRCValue(...)

As well as performing the CRC check on the written data, CRCCheck() calculates (and returns) the XMODEM CRC of 'length' bytes starting at 'start'. This is returned in the same GET_REPORT response as used for GetStatus(). As a result, this function drains the status buffer in order to retrieve the calculated CRC value.
