So a posterized image with white blacks is a sign of a bridged trace. Probe the data pins for strange voltages. That bridge also made the clock die above 40Mhz & I2C die. Now images from either camera come through at 70fps, the clocks go at 56Mhz, the SPI communication properly accesses the left camera at 1.6Mhz, but using both cameras simultaneously makes it crash.
Surprising just how fast the board layout kills high frequencies. The SPI ribbon cable dies above 2Mhz. The purely etched clock trace only carries 1/2 the voltage at 56Mhz.
