Urgent


am new for character device drivers so please help me on this questions!

An embedded system is compossed of an IMX53 board attached to an FPGA board. The two communicates through the IMX53 GPIOs, according to the following protocol: GPIO90-GPIO97(8bits) are used as bidirectional data bus. When IMX53 sends data to the FPGA board, the GPIOs are used as outputs;when the IMX53 received data from the FPGA board, the GPIOs are used as inputs, GPIO98(1bit) is used as DATAWRITE: when the iMX53 sends data to the FPGA board this GPIO must be set to one, otherwise it should be set to zero, GPIO99(1bits) is used as DATAREAD: when the iMX53 reads data from the FPGA board this GPIO must be set to one, otherwise it should be set to zero

this is not urgent for us. Please do not demand priority attention from a free community. Instead you should have chosen a useful and informative thread title that at least gave the slightest clue about the contents of your post.

Plus, it is not really clear what your question is.
