I am still working for porting i.MX6Q FEC driver after I added FreeBSD's i.MX6 FEC driver code on rtems-libbsd. But, Because my custom board have different PHY chip(RTL8201E), I did't port FEC drier on i.MX6Q board. I used fdt loading method, too. If possible, please could you let me know i.MX6Q hardware board information which you are successful for porting FEC driver ?
I don't have an i.MX6Q. I have two i.MX7D boards: https://www.tq-group.com/en/products/product-details/prod/embedded-modul-tqma7x/extb/Main/productdetail/ https://www.nxp.com/support/developer-resources/hardware-development-tools/sabre-development-system/sabre-board-for-smart-devices-based-on-the-i.mx-7dual-applications-processors:MCIMX7SABRE
On referencing, I am working to port SMP for i.MX6Q. At this time, current version is not stable. I am looking technical reason.
The i.MX6Q uses a Cortex A9. We already have SMP support for this core on other BSPs (Xilinx Zync, Altera Cyclone V, Realview). You only have to implement the _CPU_SMP_Start_processor() function. The code for this is available in FreeBSD for example.
