No, my comment was that for completeness there should be an I2C_M_NOSTO

You should probably state which kernel and i2c driver you are using - there are
a lot of different versions around.

Thanks for the info! Yes, I think that having an I2C_M_NOSTOP option
would do what I want, but that option is not available in the kernel I'm

Try to give No ack after readin
Greetings all -
I am trying to talk to an I2C device (Analog Devices AD9888) using the
MPC860 CPM I2C interface from userland.
Writes work fine, but the chip requires a strange write-read sequence
for reading back registers. For example, to read a register:
Start signal
Slave address (r/w/ bit
hello everybody,
i use a mpc860 with iic,fec and ethernet at SCC3; iic-communication normally

iic-communication stops with error
... iic-read; short, wanted 32 got 1 ...
also the data seems
