Which bus do you see the device on in i2cdetect? You said earlier that you were using the i2c-i801 driver, which is expected for an Intel motherboard. However you say that the PIC is connected to an SMSC chip, and not the Intel south bridge? Are you sure? If you are, what is the name of the SMSC chip in question? Which i2c bus are you running your program on? The "SMBus I801" one? Note that it is not entirely impossible that the block write support in the i2c-i801 driver is broken. This is a driver which is mostly used to access SPD EEPROMs and hardware monitoring chips, to which you never write blocks. > I can provide shell-access to the box if it helps. Thanks, but no thanks. I may try to help you but I'm not going to do all the work for you ;) -- Jean Delvare _______________________________________________ i2c mailing list [email protected] http://lists.lm-sensors.org/mailman/listinfo/i2c
