Dietpi: Odroid N1

[Fourdee]

Beta image:

- http://dietpi.com/downloads/images/DietPi_OdroidN1-ARMv8-Stretch.7z

Known issues:

• Device "sometimes" fails to boot, resulting in a system hang. Workaround is to wait for a failed boot (no heartbeat), then press the reset button. https://github.com/Fourdee/DietPi/issues/1519#issuecomment-368234302

Pending:

• GPU support/driver install dietpi-software
• Kodi (pending Meveric's binary)

---

General benchmarks

• USB drive = Crucial MX100 SSD via onboard SATA interface
• CPU bench (Compare with other devices https://github.com/Fourdee/DietPi/issues/1253#issuecomment-346881878). Fastest we've seen of any non-x86_64 SBC.
  

CPU/RAM stress test:

🈯️ - Never exceeds 54'c, fan automatically manages the temps fine. No thermal throttling noticed.

Notes:

• Case was fun, although, needs a step by step guide for all users
• Molex power fitting is extremely tight, may bend/break board for some users if done incorrectly.
• Onboard SATA slot lacks the clip system with SATA2.0+, means the cable is likely to come out unexpectedly.
• There is some strange satisfaction, I simply cannot explain, when the CPU fan starts to spin up. The sound is simply stunning. Something so simple that makes the fan noise enjoyable, instead of painful.

@Fourdee

nice to see, that you have get a "engineering samples" from hardkernel. 👍

Nothing over serial. Unable to debug.

Hmm ... have you give GPIO Pin: 8 - 9 - 10 a spin with a USB-to-UART adapter? 115200-8-N-1 ?

[Fourdee]

@k-plan

6-8-10

Will give 8-9-10 a shot 👍

[k-plan]

@Fourdee

What UART adapter do you own?

With 5V, 3.3V or 1.8V interface?

http://www.hardkernel.com/main/products/prdt_info.php?g_code=G134111883934

Do you have a level shifter?

@Fourdee

Known issues in the engineering sample PCB:
...

• The UART port on the 40pin GPIO header doesn’t work due to a missing power line in the level-shifter circuit. We will solder a wire on the PCB to solve this issue which will be corrected on the mass production version.

ups ... sorry.

[Fourdee]

@k-plan

ups ... sorry.

Thanks 👍 No worries, my fault for not being able to keep up.

@Fourdee

edit:

The default baud rate for RK3399 is 1500000,Some USB to serial chip baud rate can not support 1500000，So before you buy it, make sure it supports 1500000.

RK3399 use the following serial parameters:

• Baud rate: 1500000
• Data bit: 8
• Stop bit: 1
• Parity check: none
• Flow control: none

Thanks, i'll revisit this after: https://github.com/Fourdee/DietPi/issues/1555

Info Odroid N1 engineering sample PCB Serial Debug (UART)

• Known issues in the engineering sample PCB:
  pin 38 on the gpio is 1.8 v out..so it seems to me that would be it..as it provides the missing power rail .for the serial uart

• The RK3399 has 5 UARTs, but the N1 is using UART #0 for serial console

https://wiki.odroid.com/odroid-n1/hardware/expansion_connectors#expansion_connectors

• What are the voltage specs on the N1 uart?
  Will any of my Odroid UART boards work on it?

  You can use our USB-UART kit with a 4pin connector on the N1.

• Ok I'm connected and have serial console access

Alpha test image available: https://github.com/Fourdee/DietPi/issues/1519#issue-297886100

[Fourdee]

Aside from the reboot issue (hardware issue on the dev samples, or kernel issue, unsure), device runs flawlessly.
We'll implement Kodi and GPU at a later date, pending Meveric's packages.

Released under BETA status on dietpi.com.

Completed (for now).

[Fourdee]

Re-opened to remind me to check serial again:
https://github.com/Fourdee/DietPi/issues/1519#issuecomment-368595231

[Fourdee]

Completed (for now), sent my dev sample to @midwan 😃

Will order a new one and re-do image when mass production starts.

[MichaIng]

@Fourdee
Was this ever really released with mass production?
Now superseded by Odroid N2: https://wiki.odroid.com/odroid-n2/odroid-n2
And we have zero Odroid N1 users: https://dietpi.com/survey/ 🤔

Ah, indeed cancelled: https://www.cnx-software.com/2018/06/24/odroid-n1-canceled-due-to-ram-supply-issues-odroid-n2-coming-later-this-year/

[midwan]

@MichaIng
It wasn't, it was aborted before it was mass produced due to high costs.
The N2 which just came out replaces it, like you said. :)

[MichaIng]

@midway
Thanks for clarification.

So we can replace the download slot and hardware ID in code with N2, once we get one and are able to create an image for it.

[Fourdee]

@MichaIng

Yep 👍
Odroid N2 already arrived (dev sample). Waiting on ARMbian/Meveric pre-images.

I could simply use the kernel from current test image and switch to Debian, however, would rather wait for a pre-image we can roll out that supports future kernel updates.

[MichaIng]

@Fourdee
Thank is great. I opened a new issue to work on this: https://github.com/MichaIng/DietPi/issues/2623
Meveric image already exists, but still WIP and lacks graphics driver.
