Hi:
Hardware Design: [ UB941 + UB948 ]
serializer ub941 settting:
UB941_write(0x01, 0x08) //Disable DSI
UB941_write(0x5B, 0x07) //Forced Splitter Mode
UB941_write(0x4F, 0x8C) //Set DSI_CONTINUOUS_CLOCK, 4 lanes, DSI Port 0
UB941_write(0x1E, 0x01) //Select PORT0
UB941_write(0x03, 0x9A)//Enable I2C_PASSTHROUGH, FPD-Link III Port 0
UB941_write(0x1E, 0x02) //Select PORT1
UB941_write(0x03, 0x9A)//Enable I2C_PASSTHROUGH, FPD-Link III Port 1
UB941_write(0x1E, 0x01)
Question:
I can access port0 948 through i2c slave address 0x2c, and UB941's reg 0x06 can readback port0 remote UB948 8bit addr is 0x58,
but select to port1 , i can not access port1 948 through i2c slave address 0x3c, and UB941's reg 0x06 can readback port1 remote UB948 8bit addr is 0x78,
How to config reg to access port1 948 in Splitter Mode?
Thanks.
