Other Parts Discussed in Thread: TDA4VM
Tool/software:
Hi,
We ported the TP2855 driver to the TDA4VM on SDK 10.0, but only the first camera was working.
We expected four sinks to be mapped from pad1 to pad4 on ticsi2rx.
To address this, we modified j721e-ticsi2rx.c and cdns-csi2rx.c by adjusting the routing and increasing the number of routes from 1 to 4, mapping each accordingly.
Although this approach worked, we believe it is not the correct solution. How can we enable virtual channel support without modifying these source files?
