Unable to install DietPi OS on Nano Pi R6S

I tried to follow the FriendlyElec guide to flash the DietPi image to the eMMC storage of the Nano Pi R6S. Below are my steps:

1) Download an “eflasher” firmware from network drive(in the “01_Official images/02_SD-to-eMMC images” directory), extract it and install it to a TF card ;
I downloaded this file directly from FriendlyElec Google Drive:
Then flashed it to an SD card via the Win32Imager tool

2) Eject and insert the TF card to your PC, after a “FriendlyARM” device shows up(Under Linux, it is a “FriendlyARM” directory), copy an .img or .gz file to the TF card.
I downloaded and unzipped the image file directly from our website

  1. Open the eflasher.conf file on the TF card, set “autoStart=” to the name of your image file, such as:
    In addition to third-party image, official image files which with the ‘-sd-’ word in the filename are also supported, for example: rk3NNN-sd-friendlywrt-21.02-YYYYMMDD.img.gz

Below is the content of the eflasher.conf file:

; This is the eFlasher configuration file.
; See http://wiki.friendlyarm.com/wiki/index.php/EFlasher for detailed information.

; Automate OS installation at system startup,
; Use the "autoStart" field to specify the image path or RAW image file,
; The RAW image file can be a gzip compressed file,
; The RAW image file extension must be ".raw" or ".gz",
; Available values: debian-bookworm-core-arm64

; If the "autoExit" field set to true, the eflasher-gui will automatically exit after burning or restoring is completed, 
; You can do something else after burning or restoring by modifying /opt/run-eflasher.sh.

; Don't erase the flash before burning, useful if you only want to update part of the system files

; HDMI overscan option, examples:
;	 screenSizePercent=auto
;	 screenSizePercent=90


4) Eject the TF card, insert the TF card to NanoPi-R6S, power it on it will automatically install your firmware. You can watch the installation progress by observing the LEDs’ status.
I put the SD card back to the Nano Pi R6S, it does not detect the DietPi image

(1) What am I doing wrong?
(2) Is there a better known-working process I can follow?

Thank you very much!

Since the forum doesn’t allow me to post multiple screenshots, I post it here as the screen of the R6S after boot up.

Why not flashing DietPi on your TF card, boot and complete the initial setup. Should not take that long. Once done, download the image file to your TF card and flash it to eMMC using dd command. That’s how I do it normally.

See How to install DietPi - DietPi.com Docs for installation docu.

Hello @Joulinar
Thank you for your response. I followed your guide and this have been successfully for me, the easiest method. Far better than the one in FriendlyElec Wiki for sure!
