How to run FreeBSD on new boards built on Rockchip 35XX..

renatoalencar said:
I'm also trying to get FreeBSD working on a RK35xx board, the Orange Pi 3B. Which uses RK3566, I pretty new to this, so I must confess I'm a little bit lost. I'd like to build an image that wouldn't require users to flash a new bootloader, so I'm trying to get this working with the onboard U-Boot bootloader. I've chose this board because it's a very cheap one and I could by from local resellers, I can in fact easily afford more expensive boards, but I wanted to have more people involved on this without the price barrier.

I'll try to register my progress on this thread. My goal is to have pfSense + WiFi working on this board, so this will probably be very difficult, but it should be very fun as well.

renatoalencar, do you use JTAG and GDB to debug your Orange Pi 3B RK3566 board bring up? Flirc Jeff probe is a $16 USD or 15 EU$ 2 serial channel that provides a console port and a JTAG OpenOCD interface. What do you use? What JAG probes are you interested in? Can you share your thoughts?

I really want to see this inexpensive Arm64 Quad Core A55 running desktop FreeBSD or GhostBSD so that others have a chance for a first computer running FreeBSD / GhostBSD, like the old Commodore C64 was 40 years ago. Connected to a family TV for a Display Monitor and Sound , have a keyboard and mouse to allow for creativity and building. ( Tablets and Cellphones are for consuming media , not creating digital assets ie, spread sheets, CAD Computer Aided Design Files, Editing Video, Inkspace creating digital pictures). So, I applaud your efforts and encourage you to continue.

i used u-boot from https://github.com/Kwiboo/u-boot-rockchip
just add CONFIG_EFI_LOADER=y to configs/orangepi-3b-rk3566_defconfig and it worked
i have a lot of hacks for this board most of the stuff is posted in the

Only setting CONFIG_EFI_LOADER and making a small tweak for it to work.

I've also used the Quartz64 Model A device tree and changed the clocks and reset settings for the GMAC interface and got Ethernet working. I've been trying to fix some issues with the eqos driver (proper initialization and auto negotiation issues), got some progress, although at a slow pace.

I'm using the -CURRENT image, and I just need to load the
/boot/dtb/rockchip/rk3566-quartz64-a.dtb
device tree at first boot to get serial working. It's actually being easier than I thought initially, besides the networking stuff.

GMAC Device Tree:

Code: 
&gmac1 {
        assigned-clocks = <&cru SCLK_GMAC1_RX_TX>, <&cru SCLK_GMAC1>;
        assigned-clock-parents = <&cru SCLK_GMAC1_RGMII_SPEED>, <&cru CLK_MAC1_2TOP>;
        assigned-clock-rates = <0>, <125000000>;
        clock_in_out = "input";
        phy-supply = <&vcc_3v3>;
        phy-mode = "rgmii";
        pinctrl-names = "default";
        pinctrl-0 = <&gmac1m0_miim
                     &gmac1m0_tx_bus2
                     &gmac1m0_rx_bus2
                     &gmac1m0_rgmii_clk
                     &gmac1m0_clkinout
                     &gmac1m0_rgmii_bus>;
        snps,reset-gpio = <&gpio3 RK_PC2 GPIO_ACTIVE_LOW>;
        snps,reset-active-low;
        /* Reset time is 20ms, 100ms for rtl8211f */
        snps,reset-delays-us = <0 50000 200000>;
        tx_delay = <0x30>;
        rx_delay = <0x10>;
        phy-handle = <&rgmii_phy1>;
        status = "okay";

I didn't try to use JTAG on this one, I need to find one and see it works with this board, looks like the SD card connection shares some pin with the JTAG interface, which may interfere with each other.

Looks like I need USB and HDMI working for this, so I'll try to do that later. I believe things should be partially in place for this.
