I am trying to bring up the USB controller on PQ2FADS-ZU with MPC8280onboard. I have finished with the initialization and transaction routines but not the ones neccessary for usbtty to work. The u-boot-1.1.2 source
Don't use such old code. Please use a current version from CVS, for example CVS tag LABEL_2005_08_12_0050
tree that I am using is a release version that is definitely not from the top of the CVS. I notice that the usbtty is only implemented for the SX1
This will become a major problem if you should ever have any problems or questions.
(1) The USB connector on PQ2FADS-ZU is a Type-A connector. Would this work as a console port?
Can it operate in device mode?
(2) What type of usb connections is neccessary for usbtty to work? I mean, is host PC running usb-host or usb-function and PQ2FADS-ZU running usb-host or usb-function?
The PC is a standard USB host, and U-Boot will register itself as a serial device.
(3) What type of cable should I use? I assume a Type-A-to-Type-A PC-to-PC
You better check what your hardware allows. Using a A-to-A cable with hartdware that is not compatible may ruin both your target board and the PC.
