Information：

                      FPGA: EP2C35F484C8N

                      Processor：DM6467

                      KERNEL: linux 2.6.18

Question :

When I write data through the I2C, I normally write, but when I read the data, I do not always able to read complete, the last byte is always lost.I captured with an oscilloscope waveforms, most of the time, I I2C read operation, the STOP signal disappeared.
The same procedure on the DM6467T platform running on will not appear above
