Re: IC-COMP driver and CCIR cameras
Hello Pedro!
Sorry, my knowledge about the special registers of this board isn't enough
to help you, but I have an idea:
How about initializing the board under windows, using a ccir config file.
After rebooting WITHOUT switching the power off, the register contents
should be the right one. Then you edit icpciAM.c (icp_amcmp_init ()) in a
manner, that you call cmp_dump_regs (), BEFORE setting all registers. So
you have an idea, how the ccir settings are and you can set the registers
directly (using cmp_write_mm). This should work EXCEPT of the I2C
registers, they you have to read out by cmp_i2c_read and write by ...

I have gone through the driver mailing list and found another very related discussion: that of Fabien Spindler and Matthias regarding how to make the IC-COMP module work for a CCIR camera. The issue was that the call "GIOC_GE_SET_CAMCNF" can't be performed since the "read_config()" function does not provide support for the IC-COMP patch. As a result, the camera configuration is set with fixed parameters (those of a NTSC camera according to Fabien's statements) in the patched "icpciAM.c" and can't be customized by means of a ".cam" file.

The issue is that such settings are (it's my guess) board-register-level ones so they are unintelligible for a common developer unless you know how the board works at the register level (information that the manufacturer does not give out for obvious reasons).
