Command Package: W 24 01 38 00 00 C7 FF 17 P ; ENTER BOOTLOADER CMD
W I2C Write
24 I2C Address, you can replace this byte with your own I2C address, this byte not include in package checksum calculation.
01 Package header 0x01,
38 Command code (enter bootloader)
00 00 Data length
C7 FF Checksum, 0x10000 - (0x01 + 0x38 + 0x0000) = 0xFFC7;
0x17 Package tail

Note: Since data length equals to 0, so no data content in this package and checksum calculate also not include data part.
Thanks but I need the document that describes the format of the other boot load commands (i.e. GET_META_DATA). Can you point me to the right document?
