Hi,
I wonder when the chapter 5.2.2.8 Future performance enhancements from the spec(https://www.dmtf.org/sites/default/files/standards/documents/DSP0233_1.0.1.pdf) will be clearly defined?
If the packet format is similar to I3C SDR mode, I have two questions:
1. Do the boardcase address(0x7E), ENTHDR command and HDR command word need to be calculated into PEC?
1.1 If yes, there is a problem that Controller can read the response in SDR or HDR mode after IBI and it will be difficult for the Target to calculate PEC before the data transmission.
2. In I3C SDR mode, the last byte is PEC of MCTP packet, but in I3C HDR-DDR mode, the data transmission unit is 2 bytes. how to identify where PEC byte is without packet length.
Thank you.
