You use the T6 (not the T6-LTS): - what wlan adapter did you install (usb or pcie, what make and what model) - what LTE adapter did you install I have the T6-LTS myself and while I don't have much problems with a rtl8822, I prefer a mediatek mt7922 or intel ax210 (mediatek can be used with hostap, i...
I had a discussion earlier with a person who bought a prebuild NAS, allowing for 2 NVME's and SATA drives's. In my opinion it is simply ludicrous: either choose NVME or SATA and be done with it, both have strong points and weak points. But I disgress. What are you looking for in a NAS? Just putting ...
If you are angry because the system does not what you want perhaps you are still thinking of ancient intel systems. With a modern Linux the TTY is not what it used to be. It is a graphical interface which emulates a console nowadays. The RK3588 is even worse in the sence that the GPU/VPU is initiali...
There was one small issue, where I wondered if you found the reason: # lspci -v -s 0004:41:00 0004:41:00.0 Non-Volatile memory controller: Kingston Technology Company, Inc. A2000 NVMe SSD (rev 03) (prog-if 02 [NVM Express]) Subsystem: Kingston Technology Company, Inc. A2000 NVMe SSD [SM2263EN] !!! U...
I saw this weekend that the M6 is currently rather good supported with Armbian and 6.13 kernel. Advantages/disadvantages of the M6 over the T6-LTS: - There is no flashrom and fixed serial usb-to-serial adapter (which I found no problem in hindsight since the emmc can be removed). - Free choice of wi...
What distribution do you use and what kernel version? With kernel 6.11.9 (debian) I get from aplay -L: hw:CARD=realtekrt5616co,DEV=0 realtek,rt5616-codec, fe470000.i2s-rt5616-aif1 rt5616-aif1-0 Direct hardware device without any conversions (HDMI audio does not work with 6.11-kernels, see the collab...
Small addition: I found the system still booting with other distributions after exchanging u-boot.

So you might try updating u-boot without changing the rest. A reinstall might be required though.
I'd say it is not trivial. I used the method mentioned on the inindev github pages: https://github.com/inindev/nanopi-r6 or https://github.com/inindev/nanopi-r6/issues/4 Perhaps instead the below ones for the T6 which are similar but more recent: https://github.com/inindev/nanopc-t6 or https://githu...
Have you tried connecting to the debug port? I think you will see the vendor-supplied 2017-version of u-boot installed. For a recent nvme an 2024.xx-version or higher might be required. Record the startup using a terminal connected to the debug port, that should confirm the problem (dmesg does not r...
Thanks for the answers.

I think the simple dc-dc adapter I wanted will not be sufficient for the 5% margin.
First question is "why don't you want to boot in Android?". My reason was I wanted to replace the system with debian completely and start from nvme. Experience learns one can roughly just erase the android image (can be restored if needed). Using rkdeveloptool or (as linux user) upgrade_to...
The M6 looks very interesting for some special purposes, especially when a optimum between speed and power efficiency is sought. But has anyone at FriendlyElec ever tried using an M6?
At least now I know why the T6 can be delivered with an optional Wifi M2.E card and the M6 not.
Hi,
Currently I'm testing with a NanoPC-T6.
Can anyone tell me what the power requirements are for the T6?

The specification tells "12V".
The schematics show "DC12V Adapter" => "BUCK +4V".

What range can I allow for? 12V +/-5% ? +/-10% ?? +/-20% ???
I have an additional question since the systems need to be used on battery power. Typically a lead battery provides 12-14V. The M6 would have a USB-PD connection with a 5-20V inut range. The T6 would have either a strict 12V connection. The Wiki states "Power supply: 5.5*2.1mm DC Jack & 2-P...
You could try to see if armbian bookworm works on your system, since armbian supports more realtek adapters than mainstream. But that might imply building your own kernel the armbian way (with try and error). Note: if you don't find 6.1 vendor kernels AND 6.10 mainstream kernels in the downloads I'd...
Hi, One could compare the T6 and the M6 in similar conditions (same network, with monitor active, keyboard attached and nvme). I would use "sudo lspci -vvv" or similar to check if aspm L1 is active for the nvme and "cat /sys/module/pcie_aspm/parameters/policy" to check if it is s...
