Re: Increase SD card size

Hi @techiekanth
Since v13.4.0 the userdata partition will extend on first boot to take up the remaining space on the SD card, there is no more need to adjust the .json file. You can use our installer or the official RPi imager.

android camera app showing green screen

I am trying to run a camera app (made with Unity3D) on RPI3B+(Emteria OS installed). App is showing green screen when camera is turned ON. Pre-installed camera app of Emteria OS is running very well. So what could be the issue with my custom unity camera app? Is there any changes I need to make to my custom app? what is the reason behind green screen?

Re: Kiosk mode not locked, settings from volume control

@gabrielsolomon ah, it's on a RockPi, that makes sense. Got a little confused as you originally mentioned the RPi4.
We've looked into it and that's the default configuration from radxa. I think we can safely remove the sound buttons so that settings are not accessible from kiosk mode. Thanks for pointing that out.
The changes will be in the next nightly: v11.1.18

Re: Getting a Syntax Error ")" on Linux Installer

@Fish , the installer is not meant for the target device. Run the AppImage or Exe on your computer/laptop to flash an SD card, which you than use on your RPi.

Re: Syntax Error

@USST The emteria installer is not built for the target architecture, e.g. RPi3/RPi4. You are meant to install the installer on your computer / laptop and flash an SD card / your device from there.

Re: Emteria NOT booting

Hey @Charlie,

here is an article in our Knowledge Base on how to set up UART on RPi https://emteria.com/kb/connect-uart-rpi please provide a full log

Re: Raspberry Pi 4 - USB Ethernet adapters

@boothroyd, it sounds to me like a missing driver config option in the kernel. I know for sure that CDC-NCM support is compiled into the kernel (see https://github.com/emteria/kernel_brcm_rpi/blob/be909b88a3fa484b792a362e25c070ee34c12fec/arch/arm64/configs/bcm2711_aosp11_defconfig#L2274), but load kernel modules can be loaded at runtime from /odm/lib/modules on the device.

Re: Raspberry Pi 4 - USB Ethernet adapters

@boothroyd That's interesting, but far beyond an usual use case. I have the feeling that some kernel modules might be missing. You can find our kernel here: https://github.com/emteria/kernel_brcm_rpi/tree/v5.10.33-q
and compile it with your missing modules; afterwards exchange it on the boot partition.

Re: Raspberry Pi 4 - USB Ethernet adapters

@smieschek, one of my applications needed support for CDC-ECM, RNDIS, or CDC-NCM devices. Using a USB network connection is more than just a way to add an extra Ethernet port. It is also a way of interfacing Android devices to additional hardware via USB, and so it is simply not an option to use the Ethernet port.

In this case, my option was to either use: a) Emteria or b) a commercial tablet connected via HDMI to a flat-panel TV, and it looks like (b) is going to be the solution for me. All Android tablets/smartphones that I've tried either support CDC-ECM or RNDIS.

If you are interested in supporting USB networking devices in the future and do happen to have one of the supported devices in the second URL, the software in the first URL can be compiled. That might let you try several industry standard protocols without having to buy extra devices:

https://github.com/hathach/tinyusb/blob/master/docs/reference/supported.rst

On the topic of other devices that failed in my tests (Emteria v11.3.0 and v.11.3.16), one of the two ASIX chipset devices was branded "H50223 HiRO USB 2.0 to Fast Ethernet Adapter" and the other was just "USB 2.0 Ethernet Adapter".

Thanks anyway.
