According to AN806, the address 0x14 should be 0xFFFFFFFF before download, but
that address will be rewrite in the code, so it is not OK for download next
As the customer said, he could only download successfully for the first time.
Would you suggest how to access 0x14 and reset it to be 0xFFFFFFFF. Or do you
have a example of I2C download.


First you should work at 100khz than 400khz for I2C. Then ADUC702X do have some
issue on  I2C with access more bytes continuously. In general, we recommend I2C
work at 100khz, and let them do as our application note.
