Well the thing is, BCM wifi chips have these IO pins that tell the BT chip what the wifi chip is doing. But CSR chips for instance don't care, they just check what the wifi chip is doing on the antenna. So those don't use those IO pins. Hence, I'm wondering if there's any use in the IO pins at all. But they must have added them for a reason, presumably because their own BT chips can use those inputs... Anyway, mostly just idly wondering, since most of the time it works fine and the EEPROM is actually done right I guess we should keep them on. johannes --=-ZM7ZLi2jHYq0OA+A5Erv Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJI1WbwAAoJEKVg1VMiehFYaogP/jUAka6Ntc+uDJURiYrydpvD G5MGnh07Ho5pgDgfaoFJYFcbrqdNXUGAxJ+ovIC2T8Wj7c0aA+GrR1x1tvLerVmp bDyEmiBPwrYZNOlGliw3kY1CXvGm8DXvSTyfQGtVl/K1BvSz19hw+CuJXEKUuV6l HAotOr9/NRihuEPr5JIRrwOx85c/D2M0PsxEB9vRgRgIc3uGWzXr9pKm0STJxnKQ F7ZW85+gYEuAhp+5yF3j9tC2KM0VkMlbRm4SgShCU7yy1hdvGR8dPaCXGmNfRZKy 8fudc8VyIRsDj32dJPHHef0DwW+G8dAe66WyIVnZGPupCg4lH80H8V3y9p9YdbKu cqE/NIJO5elIVhqDivOcJREEHiKo9F90/xKuk2102T3XzaH8vHoxzNObWnV9Hh0A b11BSodHxp+1PVjL2d4N0equ+ZS2r20tqiu/0HmuUMk0bPW9vAihU3IM7L88nM92 st+gZyAGmsRcsEqUTuMUBF8lpauNmS0QPv4Dpt82ghlyMoKhmOqktkeddJ30VS9L pKjy27Z0d+rWF6DIWgdF67CW6KaICMm4/xYb5ixd6OcaoJ5tWQGJ/XEjOoY04SGu WZtf0CsfZ8jxFFeiyF+sInVgJeZXCJQcQWcOM1s1VrDddeje++XOKK4Szx1QjY6t SRGk2ohAZbgdWpmHol0E =wjTS -----END PGP SIGNATURE----- --=-ZM7ZLi2jHYq0OA+A5Erv--
