Hi Matt1,


If your set your I2C slave address in I2C Slave To Avalon-MM Master Bridge Intel FPGA IP to 0310 for example,

Will it get 03 10 when you perform i2c probe?

I am not very sure and wonder maybe the IP support more than one byte of address size. I think it support up to 10 bit addressing mode if I am correct.


Thanks.

Regards,

Aik Eu

Hello Aik Eu,

sorry for the delay in response.

currently the work is halted, the wrong address 00 is still there.

if you can check the gui.png in my previous reply, i set only 0x10 in I2C Slave To Avalon-MM Master Bridge

my question is how a 00 comes along with the actual address 10 while performing a i2cprobe command from the Host side.
