I am having a problem with the I2C driver for a Freescale p1022tw board. There is the command on U-Boot's console to read from an I2C device:

i2c md chip address[.0, .1, .2] [# of objects]

When I read 4 bytes from a device with id 0x60, at address 0x0, I get:

tw=>i2c md 60 0 4 0000: 45 45 45 45 EEEE

These values that it returned are wrong. I can get the right values if I read one byte at the time:

tw=>i2c md 60 0 1 0000: 45 E tw=>i2c md 60 1 1 0001: 45 E tw=>i2c md 60 2 1 0002: 46 F tw=>i2c md 60 3 1 0003: 00 .

I should have gotten `45 45 46 00` or `EEF0` in the first command. In multiple readings for this device, it is returning always just the first byte value. If I try to get 6 bytes starting at address 0x2, this is the output:

tw=>i2c md 60 2 6 0002: 46 46 46 46 46 46 FFFFFF

This problem does not happen on other devices on the bus. For instance, in the device with id 0x4F, the right values are printed:

tw=>i2c md 4F 0.2 6 0000: 18 00 f6 48 00 00 ...H..

The address in the previous command has a ".2" because the chip uses 2 bytes for addresses. The first device only uses 1, so there's no need to put a ".1" (I already tested that).

I went through the implementation of the Freescale driver for the I2C communication, but I didn't change anything on it and it works for other devices. My coworker also says that the very same code works on his board. Have anybody had a similar issue or has any theory about why this is happening?

Thanks in advance.
