The documentation has been moved to: http://maemo.org/community/wiki/howto_kernelcompilation/
But here there's not the same documentation... i think some stuff has been lost on the wiki change in maemo.org :// They refer to this port as a serial port where to debug the kernel and device bootup or use it as a standard serial port. The connection should be at 8N1,115200. And the only pins "documented" are the same as in NSLU: Pin 1 3.3V (pin 1 has a white stripe next to it) Pin 2 RXD (from serial terminal program to NSLU2) Pin 3 TXD (from NSLU2 to serial terminal program) Pin 4 GND Which in the n770 are: 1 2 3 4 5 6 7 8 9 A B Pin 9 RxD (Nokia receive input) Pin A TxD (Nokia transmit output) Pin 8 and 3 are the ground. The outputs are evidently 3.3v What sounds strange to me is that I remember to have only 9 pins, not 11. (i have no n770 in front of me) and ..wtf it have two ground pins? As I said, in the mobo the V pin is directly connected to the battery, which anoys me because of the power consumption.. I think this is a design problem that only affects to developers. About the cal-tool there's nothing interesting there. It uses libcal.so.0.3.0 for all the magical stuff. I will get a look there Here some more info about RD http://maemo.org/community/wiki/RdMode Probably the first bootloader uses the retu chip to handle this serial port to support jtag or cold flashing-only. And later (if the rd-flag of serial-port is enabled) enable the serial port as is and make it available from the main cpu. (just ideas.. not sure) --pancake _______________________________________________ 0xffff mailing list 0xffff@lists.nopcode.org https://lists.nopcode.org/mailman/listinfo/0xffff
