[Unable to map network drive]

You are probably going to need a share name after the IP address smb://10.10.2.101/sharename

 

Running smbclient from the command line will give you more feedback and allow you to search for shares.

[Does not respond to hostname]

Normally your router will be responsible for translating the hostname to an IP address. So if it stops working you should look at your router's DHCP and DNS. Often both will be handled by dnsmasq. Rebooting your RockPro will renew its DHCP lease.

[UART to Ethernet]

I haven't seen modules like those before but I've used the typical 'terminal server' in a metal box. They work, the only caveat I would mention is that they can have old and non-standard web interfaces for configuration. Some of the cheaper ones I've used can only be accessed with Konqueror, not Firefox or other more common browsers. I don't know about VLANs.

[GPIO, I2C, SPI on Orange Pi 3 in C, how to start?]

I would look at mraa and upm.

[can't run kiauh.sh from putty, 'unknown' I need something more specific.]

You should ask on the kiauh github, I think the problem is kiauh not armbian.

[Cubieboard2 and armbian 6.1.33..]

The last time I tried using my Cubieboard 2 I wanted to use SPI and had some trouble. This was 2 or 3 years ago. The main reason I gave up though was the 2mm pin spacing. Maybe you found a suitable cable.

 

I would start by getting a current uboot on to it then watch it boot on the serial port. Inspect the default env, see what env file it is reading, check it is loading the overlays etc.

 

[Orange Pi 5 USB-TTL Output Garbled Characters]

I don't know how it works but in my experience it does. The Prolific page here says "Flexible signal level requirement on the RS-232 like serial port side also allows the PL-2303HX to connect directly to 5V, 3.3V, or 2.5V devices."

[Orange Pi 5 USB-TTL Output Garbled Characters]

I think the one you have will be fine. Just don't connect the red wire, even on boards which have 4 pins.

[Read-only /boot?]

If /boot is not already a separate partition I would think there is not much advantage in making it one. The main problem is machines that need a FAT formatted boot partition, as FAT is so fragile. I don't know if your Tinkerboard is one. If /boot is on an ext4 partition then fscking at boot is going to be adequate protection in most cases.

 

If you really want to mess with your partitions I think you will have to understand the boot process of your Tinkerboard in some detail. Does boot have to be the first partition? What filesystems are acceptable? What files need to be in it and what should they contain?

[Read-only /boot?]

Yes, assuming /boot is a separate partition. I do this with my Raspberry Pis as I have very unreliable power. I also set them to check filesystems on boot by adding fsck.mode=force to the kernel command line. On OSMC that is in /boot/cmdline.txt, on armbian it might be in /boot/uBoot.env, on a grub machine in /etc/default/grub (then run update-grub).

[Read-only /boot?]

Edit /etc/fstab line for boot partition and add ro option:

/dev/mmcblk0p1  /boot    vfat     defaults,noatime,noauto,x-systemd.automount,ro    0   0
 

[Why does SSH stop accepting PW, works fine after reboot.]

ssh -v ben@rockpi-4cplus

might give a clue.

[Beginner needs help with SSH/VNC/remote access]

In what way does it not work?

[Trying to control MPV Player through a python script]

I wrote the script years ago but as far as I recall I made the regexp myself. I probably just made a list of all the video file extensions I had and then listed the letters in each position.

[Trying to control MPV Player through a python script]

#!/bin/bash

TOP=/home/share/video/music

if [ -n "$1" ];
then
    TOP=$1
fi

OLDIFS=$IFS
IFS=$'\n'

find $TOP -name "*.[maowf][povgklm][gvim]" -print | shuf -n 100 > randomplaylist
mpv -fs -vf=pp=de --playlist=randomplaylist
rm randomplaylist

IFS=$OLDIFS

This will play 100 randomly selected files from /home/share/video/music and subdirectories or whatever directory you pass on the command line.

[Backup]

Take the SD card out and put it into another machine. Copy the whole card as an image. To restore you just copy it back. On Linux I would use dd for this:

sudo dd if=/dev/mmcblk0 of=backup.img bs=1M status=progress

making sure you have the right dev. It should not be mounted while you do this.

On Windows... Balena Etcher?

[Reset password root]

You are mistaken. Please reread Steeman's last post until you understand it.

[Is it possible to plug in a phone via USB to use its hotspot?]

Plug your phone in. Set it to USB tethering. NetworkManager will probably detect the connection and you can use it like an ethernet connection.

[Installing python 3.7 fails]

apt-cache search libpython3

will show you which versions are available. I would expect any version higher than 3.7 would also work for you.

sudo apt install python3

will install the latest available version.

[Can't connect on my WiFi, continuously asking for my password]

Another option I have read about is to set SECLEVEL to 0, so you would have:

[system_default_sect]
CipherString = DEFAULT:@SECLEVEL=0
Options = UnsafeLegacyRenegotiation

 

[Can't connect on my WiFi, continuously asking for my password]

If you are using WPA then you probably don't have RADIUS as that is for central auth in enterprise environments, usually they use PEAP.

That doesn't necessarily rule out OpenSSL as the culprit though.

I get the same error as you at work but have no problem at home where my router runs OpenWRT.

Perhaps there is a menu option in your router for firmware updates.

 

You could try the workaround suggested in the link I posted:

> > adding this to /usr/lib/ssl/openssl.cnf fixes the issue.
> >
> > [system_default_sect]
> > Options = UnsafeLegacyRenegotiation

It may not be quite that simple, it didn't work for me.

 

Alternatively, you could get hold of another router (gl-inet.com) that you can connect to and hook it up to your main router with a cable from WAN to LAN ports.

[Can't connect on my WiFi, continuously asking for my password]

Is your router using RADIUS?

https://www.spinics.net/lists/hostap/msg09840.html
OpenSSL has disabled insecure old TLS auth which should have been fixed 10 years ago but it turns out not everyone has.
 

Try updating your router firmware.

This is the real solution. Annoying passwords are only enforced at installation. Change it straight afterwards and forget the annoying one.

[Sale Firefly Station P2 (rk3568)]

Blimey! $369, I think I paid $129 for mine. It is a lovely machine which I hope to get working again soon. I wonder if there is a P3 in the works.

[Deleting Firmware and Blanking EMMC Menu]

I have tried the clearing of eMMC option. Unsurprisingly it cleared the eMMC and I can no longer boot to Station OS. I can still boot to Balbes' UPDATE_UBOOT image from SD card.

 

The other option is 'Delete bootloader'. I have not tried this but I think it must clear the SPI. You would definitely want a working uboot in eMMC before doing that. The question I have is if you do that and have an empty SPI will the bootrom go to the eMMC or will it hang?

 

Firefly have RK356x_NorFlash2eMMCLoader_20211209.img which suggests you need something in SPI (aka NorFlash) to redirect to the eMMC. This page goes into it. I don't have Windows, no longer have Station OS (so no ADB) and have so far failed to enter MaskROM mode so I'm a bit stuck.
