This page needs to be properly filled according to the New Device Howto and the New Device Page guide.

If a device is special, then feel free to provide a terse description of what makes this device so special. But terse, no novels, no marketing blurb.

Sunxi support

Current status

Unsupported.

However, as of this writing, the sun8i-h3-orangepi-pc target is generic enough to be safely usable with this device.

Since this is not a developer device, things like missing mainline H3 support for ethernet, HDMI/Composite out and only one active USB port does limit its current usefulness.


Images

Add MANUFACTURER DEVICE specific sunxi ROM images here. E.g. a livesuit image or some other linux image which uses linux-sunxi code. Do not put non-sunxi images here, they should live under See also. If no sunxi based images are available, this section can be left blank.

HW-Pack

Add MANUFACTURER DEVICE HW-pack specifics here. This section can be left blank.

BSP

Add MANUFACTURER DEVICE BSP specifics here. This section can be left blank.

Manual build

  • For building U-Boot, use the MANUFACTURER_DEVICE target.
  • The .fex file can be found in sunxi-boards as hyh-tbh3.fex

Everything else is the same as the manual build howto.

Mainline U-Boot

If there is mainline U-Boot support, add this section.

For building mainline U-Boot, use the MANUFACTURER_DEVICE target.

Don't forget to add
[[Category:Mainline_U-Boot]]
at the bottom of the page.

Mainline kernel

If there is mainline kernel support, add this section.

Use the FAMILY-CHIP-DEVICE.dtb device-tree file for the mainline kernel.

Don't forget to add

at the bottom of the page.

Tips, Tricks, Caveats

Add MANUFACTURER DEVICE specific tips, tricks, Caveats and nice to have changes here.

FEL mode

Make sure that your device is truly powered off. Do not leave any cables attached. Attach The UART cable and launch your serial console. Now in the same time you attach the Power cable and you send the character '2' to the device during power-up. When in fel mode you should see eraly jump fel on screen. Now you can attach a USB-cable to the USB port near the micro SD slot.

To verify you have successfully entered FEL mode, check the output of sunxi-fel version. For the Hyh-tbh3, it should look like:

AWUSBFEX soc=00001680(H3) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000

DRAM clock speed limit

DRAM is clocked at 672 MHz by the hardware vendor. But the reliability still needs to be verified. One of the ways of doing reliability tests may be https://github.com/ssvb/lima-memtester/releases/tag/20151207-orange-pi-pc-fel-test (it checks the Orange Pi PC DRAM setup in the current mainline U-Boot v2016.01-rc2 + a bugfix).

NOTE: While this test image was made for the Orange Pi PC, it also runs on the Orange Pi Plus.

Hardware Diagnostic software lima-memtester passes (survives until the red LED) lima-memtester fails Notes
User:von fritz's Hyh-tbh3 fel-boot-lima-memtester-on-orange-pi-pc-v3.tar.gz with hyh-tbh3.bin and max_freq = 1200000000 768 MHz 792 MHz no Heatsink. Up to 768 MHz passed until Loop 15 tested, 792 MHz fails with libusb usb_bulk_send error -9.

See the Orange Pi PC DRAM clock speed limit for how to perform an analysis of these results.

Device disassembly

Remove the four rubber feet on the bottom and unscrew the four micro screws, see Device_picture

Locating the UART

UART pads are located between the USB port and the A/V CVBS output jack UART howto.
