Hi,
We are using TFP410 in one of our boards. We are not able to get it to work. Following are our observations.
1. Register dump of TFP410 after poweron :
0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef
00: 4c 01 10 04 00 00 14 64 be 80 80 00 a9 db 97 22 L???..?d???.???"
10: 00 00 00 00 00 22 e1 5f ac b2 5c 48 41 00 00 00 ....."?_??\HA...
2. Before using it, we are writing the following values to TFp410:
./i2cset -y 0 0x38 0x8 0xbf
./i2cset -y 0 0x38 0x9 0xb6
3. We are feeding RGB video to TFP410.
4. We are seeing signals in HSYNC, VSYNC and Inout data pins of TFP410 (after probing using CRO).
5. After connecting an HDMI output, 0x9 register of TFP410 shows the following value : 0xb4
According to this, the RSEN bit is set. This means that "A powered-on receiver is detected" by TFP410
6. But we are not seeing (after probing) any output signal on TFP410.
Kindly tell me if I am missing anything here.
Regards
