I2C interrupts are not working on Zynq

[jeff_king]

Using a Microzed, Vivado 2014.3, Win 64-bit

Configured MIO pin 10 as I2C interrupt pin for I2C0. Anytime the interrupt is asserted the XIicPs_MasterSendPolled  (does the same thing in the Recv function) function in xiicps_master.c hangs while waiting for a completion.

The errata says something similar to this http://www.xilinx.com/support/answers/61665.html 

The errata implies that this problem only exists with a repeated start condition and only during a read operation. I am seeing problems for both xmt & rcv and I  am not doing a repeated start. Looks very much broken to me.

Thanks,

hi,

would that be possible to attach the code that you are testing?

I put the interrupt outside of the I2C handler since the driver didn't work properly.

Thanks.
