Rock pi s debian ftdi driver missing

#1

hi, I am working on rock pi s with debian, we need to use ftdi device to get data from other hardware. by using lsusb, I can see the ftdi device is in the list, but there is no ttyUSB* shows in /dev/
does anyone have an idea how can I fix it?

#2

By enabling, adding or porting a driver if not present in the kernel.

#3

do you have detial about how to do that?

#4

Make an image this way and enable what is missing:
https://docs.armbian.com/Developer-Guide_Build-Preparation/
What exactly is missing I don’t know from your post.

IMO. Just enable all FTDI related devices you find in the kernel config … perhaps stock Armbian already works for you OOB. Check that first.

Edit: I just saw this is about Rockpi S which is not supported by Armbian simple building procedure. Then manual way … Google for generic instructions and/or Radxa wiki.

If you want to use Armbian, as I did, you can use this branch from my repo: https://github.com/piter75/armbian-build/commits/rockpi-s-bring-up and build it (buster) with:

./compile.sh minimal BOARD=rockpi-s BRANCH=default KERNEL_ONLY=no BUILD_DESKTOP=no RELEASE=buster

It contains:

  • quite recent Armbian,
  • Rockchip kernel with Radxa’s and 4.4.192 patches
  • Rockchip u-boot with Radxa’s patches
  • u-boot patch to make LAN MAC address stable based on CPUID
  • almost all USB_SERIAL modules compiled :wink:
  • overclock to 1.3 GHz

I was going to bring Rock Pi S to Armbian but it has to be built from my custom repos for now :frowning:
Ayufan’s repos used by Armbian for rockchip64 builds are far behind Rockchip’s and do not have necessary commits to support RK3308.

I can build it, but it won’t run on board, only green light on, and plugin Ethernet cannot see shows in router side.

#8

Can you try to connect serial console to it to check what the error is?
Console is on UART0 which is either on 8,10 (v1.1+) or 9,1 (v1.0) depending on the board version.

I will probably upload somewhere precompiled version soon.

#9

nothing readable print out on 115200 bound rate

#10

I was going to mention it - for Rockchip platform 1500000 is default baudrate.

#11

still nothing print out. can you send me a image file and have a try?

#12

Try this image, I have just booted it.

EDIT: One more mention, there is neither WiFi nor Bluetooth in this image.

thanks a lot. one more thing is what’s the password? I tried password, and it is not working

#14

It is Armbian so default root password is: 1234 and you need to change it on first login (you can do it over ssh). At the same time you are forced to create a normal user with your own password.

I wonder what the problem was with the image built by you… Did you build it with Vagrant, Docker or bare metal?
Maybe I forgot to push something to the repo. I will try to build it in pristine environment to check.

#15

I am using ubuntu to build it, I use the mini image from the armbian documents

#16

Ok. Glad that the precompiled image worked :slight_smile:

#17

Thank you a lot.

#18

Hello, I use this image and have some trouble with shutdown.
1)install images on 6 pis
2)go to shutdown each pis, each pis have different command
{
sudo shutdown now
sudo shutdown -h now
sudo shutdown -P now
sudo poweroff
sudo halt -p
sudo init 0
}
everything was okay and work/
3) sudo apt update && sudo apt upgrade -y (in each pis)
4) sudo reboot (all pis)
5) do step 2 and pis dont work, ()

#19

I have just tried the same procedure on one of my Rock Pi S with shutdown -h now and it: updated, upgraded, rebooted and is still successfully shutting down after the process.

One thing, although it should not matter at all IMHO, is that I used the latest image from this topic: Rock Pi S Armbian Buster minimal (pre-release). It is a bit newer than this one.

#20

Thanks, for answer.
I install that image, and in newer version I havent this problem, but I have problem with docker.

#21

Oh. I never optimised it for docker :wink:
