GarlicOS 2.0.2 now supports RG35XXSP

Introduction

I've finally been able to get my hands on one of these, and I am happy to confirm that the existing RG35XX+ bootloader works just fine on the newly released RG35XXSP.

This doesn't come as a huge surprise, given the almost identical hardware.

And, unlike the recently released RG28XX, it doesn't need in-software rotation for its screen to function correctly.

Upcoming hardware acceleration support

Given the wide adoption of the Allwinner H700 SoC in Anbernic's recent devices, and its glibc-compatible driver blobs, these devices have quickly soared to the top of my to-do list as potential hardware-acceleration testing targets.

In fact, I've been testing a WIP hardware-accelerated GarlicOS 2 build on these devices for a bit more than a week now and hope to have it out for public testing soon.

Known issues with Allwinner H700 devices

GarlicOS 2, at its core, is built to run on a plethora of different SoCs using a single shared operating system image.

Given this background, it's a given that the same images can run differently on different hardware, and the Allwinner H700 devices have acted as somewhat of a floodlight to really highlight this.

All Allwinner H700 devices, at this point in time, suffer from I/O-related slowdown issues, which rear their ugly heads as frame pacing, sound stutter, and excessive loading time issues.

I'm still looking into this, so bear with me for the time being.

Which devices are currently supported?

• Anbernic RG405M

• Anbernic RG405V

• Anbernic RG35XX+

• Anbernic RG35XXH

• Anbernic RG35XXSP (NEW)

• Anbernic RG28XX

• Retroid Pocket 2+

How to install GarlicOS?

All GarlicOS 2.X devices run off the same operating system image, booted by a custom, device specific bootloader.

The process can differ slightly from device to device, but, for the most part, the process is always the same:

• Install one of the available bootloaders on your device

• Prepare a GarlicOS MicroSD card and plug it into your device

• Boot into GarlicOS using your device's MicroSD card boot button combination (if it has one)

For exact step by step instructions, please consult your device's bootloader repository README.
