Identification

On the back of the device, the following is printed:

Remix Mini
Jide Technology Model:RM1G

The PCB has the following silkscreened on it:

JD-YZJ_8x4_V1_0

Sunxi support

Current status

Still unsupported. The Pine64 board is currently de-facto the reference hardware for working on Allwinner A64/H64/R18 support in the mainline U-Boot and the mainline Linux kernel. You can track all the progress there.

Images

Optional. 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 removed.

HW-Pack

Optional. Add MANUFACTURER DEVICE sunxi HW-pack specifics here. When empty, this section can be removed.

BSP

Optional. Add MANUFACTURER DEVICE sunxi BSP specifics here. When empty, this section can be removed.

Manual build

You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

U-Boot

Sunxi/Legacy U-Boot

Use the MANUFACTURER_DEVICE build target.

Mainline U-Boot

Use the MANUFACTURER_DEVICE build target.

Linux Kernel

Sunxi/Legacy Kernel

Use the MANUFACTURER_DEVICE.fex file.

Mainline kernel

Use the FAMILY-CHIP-DEVICE.dtb device-tree binary.

Tips, Tricks, Caveats

The SoC has the "secure boot" fuse burned, so it will not accept any standard eGON boot media (on an SD card or on the eMMC). Instead it expects TOC0 wrapped boot code. Fortunately there does not seem to be any actual ROTPK HASH key burned into the fuses, so it will not try to match against a certain key, but will load boot code (SPL) signed with *any* key.

FEL mode

Normally Remix Mini boots from the internal 8/16 GiB eMMC. If an SD card with a valid TOC0 header is present, this will take precedence and the BROM will load code from there. FEL mode is another way to access the device: to trigger FEL mode, there is a button accessible via the pin-hole, located between the SD card slot and the audio jack. A somewhat special USB cable (A male to A male) is needed to connect the upper USB host receptacle to your desktop PC, which is running the sunxi-fel tool.

FEL button pin-hole FEL button

Instead of pressing the button it is possible to have a TOC0 based bootable SD card image, which switches the device into FEL mode:

   wget https://github.com/ssvb/sunxi-tools/raw/toc0/bin/fel-sdboot.toc0
   dd if=fel-sdboot.toc0 of=/dev/sdX bs=1024 seek=8

As the SoC starts up in "secure boot" mode, FEL will be entered in non-secure SVC mode. However any random smc call will immediately return, now in secure SVC mode, so with full access to the system.

eMMC

Remix Mini has eMMC connected to SMHC2 (0x1C11000) and apparently clocked at 100MHz according to the dmesg log from Remix OS.

Device specific topic

If there are no further device specific topics to add, remove these sections.

...

Adding a serial port (voids warranty)

DEVICE UART pads

This section explains how to attach a serial port to the device. Make sure it refers to our UART howto. For a development board, you can just mention how to find the header with the pins and include a picture, and you can remove the warranty voiding warning.

Device disassembly

If necessary, provide a short description of how to open the device. Perhaps explain how the pins can be most easily popped. If pins do need to be popped, mention the Plastic tool howto.

Locating the UART

Describe how to find the RX,TX,GND signals here, and mention the UART howto.

Pictures

Take some pictures of your device, upload them, and add them here. DO NOT UPLOAD PICTURES WHICH YOU PLUCKED OFF THE INTERNET.
