Adding support for the Rockpi-S

mapaul

mapaul

I recently procured some of the excellent Rockpi-S boards, which come with full size usb and ethernet, onboard audio out, optional nand flash, optional wifi / BT (over SDIO), as well as optional POE all in a small relatively inexpensive package running on the RK3308.

My personal use-case is to build a device that can do shairport-sync (airplay) to some speakers, and probably a print server, but I can imagine a lot of other uses for them as well.

This thread is to document my attempts to get the board working, but also as I am somewhat new to Freebsd, to ask for help along the way.

My plan of action is as follows:

- Build u-boot for this board
- Bring up the board using the process in /usr/src/release/release.sh process, and ideally upstream that change.
- Document what works and what doesn't
- Investigate using nanobsd for this type of board.

If anyone has already done any of these steps (especially the u-boot work), I would love to collaborate. Also if there is a better place to communicate this please let me know.

I would like any advice on whether I should persue crochet over the /usr/src/release/release.sh process. I don't currently fully understand how I would choose between them. Also the release.sh processes seem to take an unreasonably large amount of time in order to build. Is there anything that I can do to have repeat builds at least be faster?

A better place would be freebsd-arm@ mailing list. All the ARM developers are there to find.

To make kernel module filemon persist reboots, set in /etc/rc.conf kld_list="filemon" .
 
Thanks for the suggestions!

Progress so far is slim. I have been working on getting u-boot up and running, and mostly just learning about what exactly it does, how it's installed, and how it differs between linux and FreeBSD. I'm probably missing some information on these things, but so far here is what I understand.

u-boot is roughly equivalent to the bios or EFI on an x86 device. It is responsible for bringing up DRAM and possibly other necessary aspects of the system that need to be working before a kernel can be run. It is also responsible for finding and booting into a kernel. To accomplish this job, has drivers for lots of things like disk drives, keyboards, serial ports, ethernet, among others. These allow logging, user-interaction, and ultimately finding a kernel image to boot from.

Also unlike a bios or efi, where the image is burned onto the board, u-boot is typically installed on the same sd-card or nand-flash that the device will eventually boot from. This means we have to provide a u-boot that works with both our kernel and our board and install it to the correct location of the SD card where it will be loaded.

This high level understanding of u-boot applies for both Linux and FreeBSD. I am still trying to understand the specific things FreeBSD needs from u-boot in order to boot on it.

So far I have started with the bsp provided by the manufacturer to try to build u-boot (following this guide). I did investigate creating a port of u-boot for the rock pi s under freebsd, but so far the specific chipset RK3308 does not seem to be supported in freebsd's u-boot or the upstream repo, and I don't really know all what has been customized to get it to work. So instead I am hoping to try to patch whatever FreeBSD needs into the manufacturer supplied u-boot source code in order to get it running, but the first step is just to get a working u-boot shell for the rock-pi-s so I can at least poke around.

Following the guide above, I have built idbloader.img, uboot.img and trust.img and coppied them to the correct offsets on the sd card. That does show text on the uart, but it crashloops. one cycle of the text is below:

I think I need to understand why this fails, and maybe try to boot a custom build linux kernel before I will be able to get FreeBSD running.
 
Had a small breakthrough today. I got lucky and discovered a working prebuilt u-boot intended for use with openBSD (gist). Importantly this copy of uboot has the bootefi command, which appears to be required for FreeBSD. Using these files, and the latest mini-memstick image for aarch64, I was able to put together a bootable sd card for the rock pi s. The image booted into the u-boot shell, and I was able to load the device tree and Freebsd kernel.

Code: 
fatload mmc 0:1 ${fdt_addr_r} rk3308-rock-pi-s.dtb
fatload mmc 0:1 ${kernel_addr_r} efi/boot/bootaa64.efi
bootefi ${kernel_addr_r} ${fdt_addr_r}

This did boot the freebsd kernel, but resulted in a boot loop. I am including one cycle of the logs form that bootloop here.

Resetting CPU ...

I don't really know how to figure out what went wrong in this log. but it looks like the following lines are important:

"Synchronous Abort" handler, esr 0x96000010
and
android_A[8] == 1, ABORT maskeduld not find misc partition ANDROID:I[7] == 1, IRQ maskede)" android_F[6] == 1, FIQ maskedCould not found bootable partition boot

Which seems to have multiple strings on top of one another. I can't really tell if it's
Could not find misc partition Found bootable partition boot

or
Could not find misc partition Could not found bootable partition

If you are asking for help you really should subscribe to the freebsd-arm@ mailing list. All the ARM developers are active there. It's more likely to find on that list a helping hand than here in Forums. FreeBSD developers are rarely on Forums, if at all.

It could take longer to figure out a solution alone here than to collaborate with members of the freebsd-arm@ list. You can expect there members with substantial understanding of the problem and the one or other might pointing in the right direction or maybe there is already a same/similar work in progress.
 
Thanks T-Daemon, I have already done so and have gotten some response there. I was planning to still log my progress here, since it's easier to format code and text on this forum than in an email.
 
started to play with it, seems needs some kernel drivers to work
after looking at the boot log looks like it needs
rk3308_cru (clock) and most likely some ethernet patches

13.2 or 14 behaves the same
u-boot is leeched from the openbsd gist above
will try to hack a clock driver

u-boot is leeched from the openbsd gist above
Click to expand...
I just "ported' the FriendlyElec NanoPC-T4 with new u-boot port for my personal usage.
Basically I just cloned another RK board port with same CPU. (RockPi4 u-boot) and adjusted the defconfig for the NanoPC-T4 in the Makefile and that was it. Compiled my port and it created u-boot and dtb for the board.
I like the master port approach. Remember to backup those port patches!!

I putzed around with NetBSD and OpenBSD u-boot for my board before I decided to build my own port.

The problems I see is mainline u-boot seems barebones on some platforms.
Plus mailine is slow to bring new stuff in.

My next challenge is out-of tree u-boot.
Tinkerboard2 has their own tree and I need to figure out how to compile u-boot by hand.

I captured this from a port compilation.
gmake ARCH=arm DESTDIR=/usr/ports/sysutils/u-boot-rock-pi-4/work/stage rock-pi-4-rk3399_defconfig

Might need the long form I dunno.

I was wondering why you are using a 6 year old u-boot.
I see why. There is no defconfig in mainline u-boot for the board.
That seems to make my point about mainline being slow to add boards.

And why I need to build my own Raxda u-boot tree.

I hate trusted.img and everything about the concept.
rkdeveloper and blobs. It stinks. I do like my NVMe on arm64.
 
there is a rk3308_evb_defconfig or something and i tried a quick hack of the rockpi64 u-boot port and it failed to build
i resorted the easy way just used prebuilt blobs cause i wondered if it boots at all
if i succeed in hacking a clock driver then ill try build a proper u-boot (now i have to specify currdev and load the dtb everytime which is annoying)
soc specific clock driver code is really short but the initialization of some tables structure is fscking ugly

i have it booting multiuser but still not very useful
ethernet does not work, usb seems dead
my "clock driver" has lots of warnings
at least the sd card works and i have a root file system
 
ok I have pinctrl and gpio
also usb seems to work
ethernet still no go

created a rockpi-s image out of FreeBSD-13.2-RELEASE-arm64-aarch64-ROCK64.img
seems ok
would be nice to have pwm-regulator driver
 
No MMC on your Rock Pi-S ??
They are dirt cheap but I can't find the MMC version on ebay

That would be ideal for me.

Rockchip RK3308 64bit quad core based mini SBC An extremely "rocking" mini computer for your projects! Rockchip RK3308 Quad A35 64bit processor with built-in VAD 256 / 512MB RAM versions USB 2.0 OTG (type C) + USB 2.0 HOST (type A) RJ45 10/100Mbit Ethernet optional PoE (additional HAT required)...

512MB without BT/ WIFI with 4GB NAND
Sure like the sound of POE too.
 
dtb has a 32khz rtc external clock but im not sure if it works or not

anyway it is probably the cheapest 64 bit arm board
performance is not great about the same as the nanopi neo (h3)
rk3308 is cortex a35 which i understand is a kind of low power a53

probing/attaching drivers in a specific order is painful
i need clock => pwm => regulator for the cpufreq_dt to work
