With the boot-issue now resolved, the last nightly enables overlay-support for uart1. This is one more step towards working bluetooth on the lite2 and Orange Pi 3. Anyone interested is invited to do further testing. So far, I can enable the uart1 overlay either in armbianEnv.txt or via armbian-config. This gives us /dev/ttyS1 - at least it's there in dmesg and /dev/ttyS1 exists. Since the bluetooth module is connected via uart1, the next steps are to attach it. From my understanding, this needs the hci_uart module, which can be loaded via $ sudo modprobe hci_uart In addition, the btbcm module is required but this should be already loaded. So 'sudo modprobe btbcm' should not be necessary. You can verify if it is loaded via: $ lsmod | grep btbcm This in place, we should be able to attach the uart-port using hciattach. Now this is the point, where I am stuck. Typically, you do something along $ sudo hciattach /dev/ttyS1 bcm43xx 921600 noflow - However, I tried a couple of different baudrates as well as with and without flow-control without success. According to a couple of related posts, on success, one should see that the firmware is being loaded at this point. Any ideas or suggestions?

Dear Martin, I am pleased to let you know, that the recent nightly from today works fine on the lite2! Thank you and all others here who contributed very much! Further, I can enable now uart1 and it shows up. I just was not able yet to set up bluetooth. Will post my results in the according thread. Keep up the good work!!

Perfect, thank you! So it'll be online in the coming nightly, right?! I'll try tomorrow and let you know!

Just tried the current nightly. Lite2 boots, however Wifi is not working. I can see some of the networks on 2.4GHz, no 5GHz. Connecting is not possible.

Great, thank you. I'll post in case I encounter any issues.

FYI: The current nightly Armbian_5.86.190511_Orangepilite2_Debian_stretch_dev_5.1.0.7z does not work yet on the lite2. It freezes on boot.

Is the automatic nightly built for the lite2 still paused?

What if ttyS1 already exists? And is the ttyS1 uart1 overlay available and working with the new nightly now?

Thank you again. Will flash the upcoming nightly tomorrow then and let you know.

It does not boot.

I made a fresh install of the 0423 nightly. Then # apt update # apt upgrade # reboot -> fubar. Is this caused by the missing cpu0 reference mentioned above?

Great, thank you! I am just about to update my device. In case it fails I'll let you know...

Since there is a new nightly for OPi lite2 now, is it working again?

Same issue on the lite2. Fortunatelly, I had a backup of Armbian_5.82.190423_Orangepilite2_Debian_stretch_dev_5.0.7.7z Can I do anything to help identify the issue?

Just in case nobody noticed yet: Current nightly as of May 2nd does not work on the lite2. Probably the issue exists since a few days. After my last apt upgrade on wednesday, my board did hang on boot. After a fresh install with the current nightly, it does not boot as well. These are the last lines from verbose boot output:

What kind of stick is that?

In an effort to enable Bluetooth on the OrangePi (Lite2 | 3) I am stuck at enabling UART1 via overlay. According to the schematics, the AP6255 is connected via UART1 (PG6-PG9) to the H6 SoC but not defined in the dtb. Since there is a dtbo which looks promising at /boot/dtb/allwinner/overlay/sun50i-h6-uart1.dtbo I tried adding an overlay to /boot/armbianEnv.txt - manually and via armbian-config. Both did not work out. In addition, I also tried adding uart1 to the dtb, without success. What am I missing?

I tried a new approach on bringing bluetooth to life... With the current nightly, I noticed some complaints about a missing firmware: [ 11.484843] brcmfmac mmc1:0001:1: Direct firmware load for brcm/brcmfmac43455-sdio.xunlong,orangepi-lite2.txt failed with error -2 Which was easily fixed by root@orangepilite2:~# cp /lib/firmware/rkwifi/nvram_ap6255.txt /lib/firmware/brcm/brcmfmac43455-sdio.xunlong,orangepi-lite2.txt But UART1, connected to the ap6255 according to the official schematics is not defined in the dtb I found at /boot/dtb-5.0.9-sunxi64/allwinner/sun50i-h6-orangepi-lite2.dtb Now I am stuck with bringing UART1 aka /dev/ttyS1 to life. So far, I tried adding an overlay to /boot/armbianEnv.txt: There is one which looks promising at /boot/dtb/allwinner/overlay/sun50i-h6-uart1.dtbo So adding 'overlays=uart1' was the next step but I still don't get ttyS1 to work. Comparing the other dtbos, I noticed that some contain definitions for the RTS/CTS pins dtc -I dtb -O dts /boot/dtb/allwinner/overlay/sun50i-h6-uart2.dtbo What am I missing? [By the way, I also tried adding uart1 to the dtb, without success...] Schematics are at http://linux-sunxi.org/images/4/4c/OrangePi_Lite2_Schematics_v2.0.pdf

Just made a fresh install and reboot works fine! Great! Thank you for your support!!

Ok, I connected a TTL cable to the serial port but besides the line I get nothing else. Do I need a fresh install of the nightly version? Because I just did 'apt upgrade'... Or is there a way I can keep my existing setup?

Not yet. Will try it and let you know what I see...

Dear Martin, thank you for your reply. I am on ARMBIAN 5.82.190422 nightly Ubuntu 18.04.2 LTS 5.0.7-sunxi64 But reboot does not work. Am I supposed to do anything else besides upgrading to the latest nightly? Thank you in advance!

Will the reboot fix also work for the OPi Lite2?

Thank you for bringing USB3 to life on the lite2 again!
