This page needs to be properly filled according to the New Device Howto and the New Device Page guide.
Handheld gaming device built around an Allwinner H700 CPU. There is also an -H variant, which is in a horizontal form factor, and adds analog thumb sticks and a second USB-C port. One of the first devices with an AXP717 PMIC.
Identification
On the back of the device, the following is printed:
Anbernic RG35XX plus
The PCB has the following silkscreened on it:
RG 35XX Plus_V4 2023-09-25
Sunxi support
Current status
Mainline support is work in progress. On top of the generic H616 support (which misses display capability at the moment), this device requires support for the LCD and the AXP717 PMIC.
Working parts (with currently WIP patches):
- Basic U-Boot support (https://git.sr.ht/~tokyovigilante/u-boot)
- DRAM init (based on the T507).
- AXP717 PMIC driver (u-boot, kernel)
- Partial device tree (https://git.sr.ht/~tokyovigilante/u-boot)
- WiFi (already supported by mainline rtw88 driver)
- Bluetooth (already supported in mainline)
- Power LED
- GPIO gamepad buttons
In-progress:
- H616 Display engine (not device specific)
- generic RGB LCD support (H700 SoC specific)
- HDMI port
- Mali GPU enablement (supported by Panfrost, just needs platform power domain driver)
- Video Engine (not device specific, H264/H265 HW acceleration) (via Cedrus)
- Sound output
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.
Manual build
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
Mainline U-Boot
Use the MANUFACTURER_DEVICE build target.
Mainline Linux Kernel
Use the FAMILY-CHIP-DEVICE.dtb device-tree binary.
Tips, Tricks, Caveats
FEL mode
Booting with a USB-C cable connected to the USB-OTG port (at the bottom of the device) without an SD card inserted triggers FEL mode.
information from vendor firmware
Please note that this is not usable for mainline kernels and contains a lot of nonsense. It is however a decent source of information, given the lack of schematics:

Adding a serial port (voids warranty)
The right side of the main board (as viewed from the rear after removing the cover) contains UART howto headers. This presumably voids the warranty, but there is no specific warning about this on the device.
Device disassembly
Remove the Torx T6 screws from the rear case, and remove the battery cover. The case back will pop off with minimal effort, revealing the mainboard. Unplugging the battery will allow the rear case to be fully removed.
