I repeated the last steps with original file name, just to be sure.

This looks exactly as it should, right?

Ok, I figured it out. wget from github gave me a wrong uboot. Better add a md5check to the procedure

Sorry to bother again.  
Partial success, I have the new uboot installed, see screenshot.  
However, I can not boot anymore.  
I flashed "openwrt-ar300m-4.3.17-0607-1717695110.img" - no change.  
I enable the switch and moved to nand - no success.

Can you flash the correct nor firmware

Thank you for the fast reply!  
Is this really correct?  
It is a nand/nor version, not the m16.  
Or does this file ensure, that small memory is flashed?

Hello @alzhao ,

I did what you proposed and flashed the AR300m16 bin-file , and hey, it is no brick anymore!  
However, it is not booting from NAND anymore, only from NOR. Switch left/right on/off - no differenence.  
I reflashed the openwrt-ar300m-4.3.17-0607-1717695110.img file - no change.

Is there any way, to re-enable the NAND again, please?

I also tried

##Reset to default  
fw\_printenv  
fw\_setenv boot\_dev  
reboot

because boot\_dev was off, no change

Regards, Reiner

Try to this command to clear the bootcount -\>0 in the SSH:  
`FW_SETENV Bootcount 0`

and select 'Disable Switch' button on the Uboot page.

Thank you @bruce,

I did as you proposed. I checked, that "fw\_setenv bootcount 0" worked. Switch is disabled.  
Unfortunately, I end up again with "bootcount=4" and the booted NOR firmware.  
Something else wrong?

When you boot another time, should it go to Nand?

Sorry, no, NOR again.  
Since the uboot update I booted many times, never seen the NAND again.  
Have we reached the point, where I should read the serial console?

Yes. Should check what is happening via Serial.

This should be clear. Asking guys to check.

Seems that it is a problem of new uboot version with old production. But I am not totally sure.

Hello, to find the ART partition using cat /proc/mtd. After locating the ART partition, you can use the hexdump command to view the information within that partition. After that, please send me a screenshot of the information. Thank you.
