  1. nanoPi M4 running Armbian 21.02.1 Buster with Linux 5.10.12-rockchip64. Attached are two identical B25 USB Bluetooth Transmitter Sticks which are supposed to transmit the same MP3 stream (provided by Mopidy or Shairplay Sync). The following screenshot shows just a single B25 stick attached, the second one has yet to arrive. I expect them to all have the same USB ID ID 0a12:1004: Here’s the problem: After each reboot the system (or ALSA?) gives the B25 stick a different card number in aplayer -l (in the screenshot above B25 is card #2, on the next reboot it could switch position and be #1). Question therefore: How can I make two identical B25 USB soundcards to always stick to the same card number, so the assignment in asound.conf is guaranteed to still be valid after a reboot AND furthermore output to both USB soundcards in parallel? If come across older solutions, which rely on modprobe.d, however this doesn't show any effect, so I assume it's no longer valid for Kernel 5.x. Furthermore this one. TIA for your help!
  2. I would love to see support for modems based on the SIM7070G chip. Along with Quectel’s BG96, SIMCom’s 70x0 and 7x00 families seem to be the leading choice when it comes to IoT-related applications with LTE-M and NB-IoT. Shenzhen-based AND Technology manufactures and offers two very affordable modems (< USD 25) using the SIM7070G: BK-SIM7070G (a break-out board with serial interface) -> AliExpress DG-SIM7070G (a USB stick/dongle) -> AliExpress Sidenote: Waveshare has a Raspberry Pi HAT based on the very same chip –> SIM7070G Cat-M/NB-IoT/GPRS HAT SIMCom as chip provider offers excellent documentation on their website. I've put all files list below in a ZIP archive which can be downloaded here. I've also opened a github issue on this, in case you want to discuss there.
  3. I am looking for ways / support to run Armbian (no release preference; any version would be good) on the tolino epos 1 eInk display eBook reader (built by taiwanese manufacturer Netronix under model ID 37NB-E70Q2M+4A2). The device currently/by default runs Android 4.4.2. I'm able to flash customized 4.4 images via fastboot and have ADB control (Android Debug Bridge) via USB and Wifi. I've identified the following key components: Freescale i.MX6 SoloLite (MCIMX6L8DVN10AB) CPU. Version with GPU and EPDC (Electrophoretic Display Controller; a feature-rich, low power, and high-performance direct-drive, active matrix EPD controller. It is specifically designed to drive E Ink EPD panels, supporting a wide variety of TFT backplanes). Realtek RTL8189FTV – Wifi only, no Bluetooth TI TPS65185 – Single Chip Power-Management Solution for E Ink® Vizplex™ Electronic Paper (E-Paper) Elan eKTF – Touchscreen Controller Ricoh RC5T619PMU – Power Management Samsung KLM8G1GEME – 8 GB eNAND Nanya NT6TL xxx – 512 MB RAM The device will be used as internet-connected display device with no user interaction through the touch-screen. What I need / what I don't need: mandatory: access to a console via USB very desireable: Wifi support not mandatory: touchscreen support mandatory: support for those Chinese, Qualcomm MDM9200/9600-based 3-in-1 LTE 4G USB Modems with Wi-Fi Hotspot (attached via USB OTG cable, used as direct modem, not as Hotspot) Possible? If so, how? e.g. How to create an image supporting the listed components? And: How and where to flash it? (There is no SD card slot, I must flash the any Armbian image to the internal 8 GB. Using fastboot? Stick to the existing bootloader or replace it? (Worried about bricking the device). Sorry for the barrage of questions.
