Hi,
I am trying to bring up the USB communications between two logicpd boards (omap 37xx) sitting on a custom mother board. I am running 2.4.2 BSP.
USB functionality seems working, I can enable usb0 on each side with RNDIS adapter. However, we do have a camera sensor sitting on i2c bus 3 address 0x48, and its failing to respond to any i2c writes with error code 121 (remote io error). The same sensor works fine, if I don't bring up the USB controllers.
I do notice that, the MFD twl4030 pmic chip is also using address 0x48 on i2c bus.
The question is, why / how the USB controllers effect the i2c bus 3 in any way..? Is there is kernel configuration that I am missing to make PMIC chip not to interfere with i2c bus 3..?
Any help is sincerely appreciated.
