Tool/software:
Dear Ti experts,
I'm trying to do Line concatenate in forwarding mode with 2x 935's connected to the 954 but with no success
What I'm doing software wise:
# DeviceAddress,RegisterAddress,RegisterValue,7-bit Device Address ? , 16-Bit RegisterAddress? , Read with Stop ?, Waittime between lines
0x60,0xC,0xAB,0,0,0,0
0x60,0x10,0x91,0,0,0,0 # FrameSync signal; Device status; Enabled

0x60,0x4C,0x12,0,0,0,0
0x60,0x72,0xE4,0,0,0,0 #VC1
0x60,0x33,0x03,0,0,0,0 #enable CSI continuous clock
0x60,0x21,0x3C,0,0,0,0 # forwarding line concat
0x60,0x20,0x00,0,0,0,0 # stream from both RX ports
With this configuration I see no data being received.
But when using one channel at a time, by doing:
0x60,0x33,0x03,0,0,0,0 #enable CSI continuous clock
0x60,0x21,0x01,0,0,0,0
0x60,0x20,0x10,0,0,0,0
or
0x60,0x33,0x03,0,0,0,0 #enable CSI continuous clock
0x60,0x21,0x01,0,0,0,0
0x60,0x20,0x20,0,0,0,0
I can see video stream from individual channel.
Another thing is, if i enable both rx channel by setting 0x20 to 0x00 and using RR by setting 0x21 to 0x01 (or leave it default) i see video data but is scrambled...
Some notes that will help better understand the situation:
- 0x60 is the address of 954 DSER
- the two 935 are operated in synchronous mode (0x60,0x58,0x5e)
- MIPI data rate from each sensor is: 400 Mbit/s X 4 data lanes
- No matter if using continuous or non-continuous CSI clock (0x60,0x33,0x03 or 0x01) issue still present
- I tried also line interleaving and basic forwarding 0x21,0x04 or 0x21,0x28, same outcome: no data output from DSER
What am I missing?
I appreciate your kind support in advance.
Best Regards,
Veniamin
