Hi,
I work with CYT2B73CAD.
I have a problem with internal bootloader. In paragraph 1.9 of document 002-27076 Rev. *B (Traveo II Bootloader) shown example command/response sequence. But after Program Data command I have CY_BOOTLOAD_ERROR_CHECKSUM error code. What am I doing wrong?
I send data via 500kBod CAN bus. CAN frames sequence shown above.
Solved! Go to Solution.

Hi Dmitriy,
the checksum of the Program Data command in the AppNote is wrong.
The Checksum is the 16-bit 2s complement of the sum of every byte from Start of Packet to the last Data Byte (the byte before the checksum) in each command. According to my calculation the correct checksum of the Program Data command is 0x38, 0xF6 and not 0x0A, 0xF7.
