DLPC900: Controller/DMD incompatible problem in custom design

Part Number: DLPC900
Other Parts Discussed in Thread: DLP6500FLQ, DLPLCR65EVM

we are designing a custom board with dlpc900 dlp6500flq(typeA)
the design difference is no swap for A/B channel, no swap for bit order
we update firmware with:
uncheck DMD bit swap channel A, uncheck DMD bit swap channel B, uncheck DMD swap AB channels and Disable HDMI/DP receiver 
When we flashed the firmware, reboot, the heartbeat LED blinking, on the GUI "Controller/DMD incompatible" was checked.
What could be the reasons for this problem, how to debug this problem? Thanks!
The design was referenced dlplcr900evm and dlplcr65evm, but from the two schematics we can not be sure how DLPC900 connect to DLP6500flq, in schematics the net names of the connectors are not one to one correspondence.
How to connect dlpc900 with dlp6500flq correctly?
Thanks!
