Hi Bo,
To keep it simple, we need a microcontroller driver that accesses a few
peripherals on the board, not just Ethernet(GMAC), also UART, GPIO, I2C, etc.
No human intervention. One boots on power up and the driver would need to load
and run at boot time and access the hardware (hopefully by interfacing with
existing dedicated drivers or by replacing them).
I think the peripherals you mentioned are working with the mainline
u-boot. If the one you tested doesn't work, please just let us know that.
Hence the questions on creating a device driver under uboot. If you can point
to specific documentation (possibly a miscellaneous driver category) we would
greatly appreciate it. Creating a device tree file from scratch (because atmel
did not provide one) seemed like a good deal of work without proper examples
and we were looking for more tutorial.
Thank you for your help.
With Best Regards.
Steven.
Best Regards,
Bo Shen
