I cannot program for the life of me (for now) si, I'd like some assistance? I can get the SAA to be seen on the I2C bus, and a scan doesn't reveal the true addresses of the chips behind it (along with the previously seen reports of the addresses of the devices. I have manually probed and have obtained the actual I2C addressing of most of the chips (except for the XC device, BGA's are difficult, and the PRO1A, well I havn't gone to the length of X-ray'ing it yet, but maybe I'll have to give that a go (X-ray to get the die information, then try and resolve its function from that info) or I'll just power the device and see what it does.. wish i still had the "Pinpoint" system at my disposal. So, I'm looking for help, or a group to chat with to try and help this little device along ;o) _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
