The ROCK64

The ROCK64 is a credit-card size 4K60P HDR Media Board Computer powered by Rockchip RK3328 Quad-Core ARM Cortex A53 64-Bit Processor and supports up to 4GB 1866MHz LPDDR3 memory. It provides an eMMC module socket, MicroSD Card slot, Pi-2 Bus, Pi-P5+ Bus, USB 3.0, and many other peripheral interfaces for makers to integrate with sensors and other devices.

It supports many different open source operating systems, such as Android, Debian, and Yocto.

Upstreaming Status

Warning: The data presented in this section requires updating.

Function	Status		Component	Notes
Video Output	Linux Mainline		`rockchipdrm`	With mpv, you'll need to specify something like `mpv --gpu-context=drm --drm-connector=1.HDMI-A-1` to get it to play back on a VT
3D Acceleration	Linux Mainline	Upstream Mesa	`lima`	Very recent version recommended for the best experience. Has weird glitches on HDMI output in weston.
Video Decode	Linux Staging	Broken/Not in ffmpeg	`hantro_vpu` and `rockchip_vdec`, using `v4l2-requests`	Soon to be moved out of staging, ffmpeg patch set seemingly abandoned, does not work on newer kernels. Git branch with commits
Audio	Linux Mainline		`snd_soc_rockchip_*`
Power Button	Linux Mainline		`rk805_pwrkey`	If your PWR switch does nothing unless held, this may need to be loaded manually with `modprobe` or by putting it in `/etc/modules-load.d/`
Analog Video Output	Needs porting		`rockchip_drm_tve`	Definitely needs some cleanup before it'd be ready for mainline, and needs some dt bindings written.

SoC and Memory Specification

Based on Rockchip RK3328

CPU Architecture

Quad-core Cortex-A53 up to 1.5GHz CPU
Full implementation of the ARM architecture v8-A instruction set
ARM Neon Advanced SIMD (single instruction, multiple data) support for accelerated media and signal processing computation
ARMv8 Cryptography Extensions
In-order pipeline with symmetric dual-issue of most instructions
Unified system L2 cache
Includes VFP v3 hardware to support single and double-precision operations
Integrated 32KB L1 instruction cache, 32KB 4-way set associative L1 data cache
TrustZone technology support
Full CoreSight debug solution
One separate power domain for CPU core system to support internal power switch, and to externally turn on/off based on different application scenario
PD_A53: Cortex-A53 + Neon + FPU + L1 I/D Cache of core 2/3
One isolated voltage domain to support DVFS

Frequencies & Voltages

Frequency	Voltage
408 MHz	0.950 V
600 MHz	0.950 V
816 MHz	1.000 V
1008 MHz	1.100 V
1200 MHz	1.225 V
1296 MHz	1.300 V

Power Draw

These numbers for power draw have been measured through an USB power monitor (FNB38) while running the stress utility, whereby "cpu" stands for stress --cpu 4 and "vm" stands for stress --vm 4. The former spins on the CPU, the latter stresses the memory. Real workloads are usually a mix of both. The tests were ran through ssh, with nothing besides power and ethernet plugged into the ROCK64

Please keep in mind that under real world usage, many other factors come into play. Having a display connected, running a graphical session, I/O and most importantly the connected USB peripherals can add a lot.

Helpful refresher on the formula for power (W) on DC: power = current × voltage, because the power factor is 1. The ROCK64 runs on 5V, so use that to calculate current if you need to.

Frequency	Power cpu	Power vm
1296 MHz	2.64 W	2.95 W
1200 MHz	2.32 W	2.69 W
1008 MHz	1.90 W	2.31 W
816 MHz	1.62 W	2.05 W
600 MHz	1.45 W	1.85 W
408 MHz	1.33 W	1.72 W
Idle (no load)	1.10 W

It appears a good upper bound for a headless setup is in the neighbourhood of 3 W, or the energy contained in 0.025 bananas per hour.

WiFi 802.11 b/g/n with Bluetooth 4.0 (optional USB dongle)

Storage

Position of the two-pin header for disabling the optionally installed eMMC module (highlighted in red)

microSD - bootable, supports SDHC and SDXC and storage up to 256GB
eMMC - bootable (optional eMMC Module)
128Mbit (16MB) on-board SPI flash memory (empty by default) - bootable? Usually accessible as a Linux MTD device at /dev/mtd0

Optionally installed eMMC module can be disabled by placing a jumper onto the two pins on the separate two-pin header, located near one of the mounting holes and two side-mounted buttons. See the picture in this section, in which this two-pin header is highlighted in red.

Expansion Ports

All GPIO pins, including UART, operate at 3.3V. (See VCCIO5 in the schematics.)

2x20 pins "Pi2" GPIO Header
2x11 pins "Pi P5+" GPIO Header (with 2nd 10/100Mbps Ethernet pins)

Troubleshooting

HDMI output disconnects as soon as it connects

Some older monitors seemingly can get into a weird state wherein the ROCK64 is unable to establish a proper connection with them. User:CounterPillow has seen this happen on an iiyama ProLite G2773HS connected over HDMI, and an Acer P225HQL connected over an HDMI to DVI adapter. The symptoms usually are that you see the monitor briefly turn on its backlight without displaying a picture, but then immediately either shutting off again or showing a "No Signal" message.

The solution is to completely power down your ROCK64, also removing its power source. Then plug in the monitor, and start up the ROCK64 afterwards. You should now be getting a picture again.

Power button doesn't do anything on a short press (Linux)

Make sure the rk805_pwrkey module is loaded, e.g. with lsmod | grep rk805_pwrkey. The module auto loading of rk805_pwrkey was fixed in the following upstream kernels: v6.0/v5.15.66/v5.10.142/v5.4.213/v4.19.258/v4.14.293 so there should be no requirement for fixes with those kernels or newer. If it doesn't show up, do a modprobe rk805_pwrkey as root. To make this persistent, create a 99-rk805_pwrkey.conf in /etc/modules-load.d/ with the content rk805_pwrkey

If it still doesn't work, make sure your init system is actually listening to the button press. With systemd, check /etc/systemd/logind.conf and make sure it's either all commented out (uses defaults) or contains something like HandlePowerKey=poweroff. You can change the short press action by setting HandlePowerKey to one of "ignore", "poweroff", "reboot", "halt", "kexec", "suspend", "hibernate", "hybrid-sleep", "suspend-then-hibernate", or "lock".

Video output is glitchy during activity

If your video output glitches out while there is memory bandwidth pressure, the likely reason is that the video output (VOP) quality-of-service (QoS) registers aren't set to high priority mode.

User:CounterPillow submitted a patch to u-boot to fix this, but someone still needs to write a kernel patch to save/restore the QoS registers from the power domain driver.
