Very good, thanks for the clarification.
Great to know. Did this help you in some way? Did you just run:
setenv variableName
For each variable and then saveenv to commit?

No, no setenv/saveenv after erasing, just reboot to u-boot … envvars will then be set to defaults!

Well, I want to add that the new Uboot is way better than the NAND only version shipped with my AR300M. No MTU issues - uploading the firmware is now flawless on Windows. This is the way it should have been on release. If any current AR300M user has this old Uboot, I would highly suggest not testing unknown images on your device without upgrading Uboot to this version.
I did not even solder the board. I paid $1 at the local electronics shop for the UART and 3 female to male breadboard cables and just placed the pins in the provided holes on the board. Worked fine.
How can I do this without going to u-boot console?
What does it actually do?
What are this addresses?
Or can I at least enable netconsole in this u-boot?
EDIT: Not needed anymore, I’ve bought USB-TTL converter and did it from u-boot console.
Does anyone have a copy of the fixed uboot? The attachement on alzhao*s post seems to be gone and the bin from github still is wrong.

Here? Where? There is no attachment and no link, and as others have mentioned - the file on github is old. It does not support NAND flashing from TFTP (no “nlf” command defined per documentation in https://docs.gl-inet.com/en/2/hardware/ar300m/ ) and the mode switch is not usable without physical case modifications.
The post is old so links was lost.
But I just verified this issue. There is a problem and pls allow some time to find out. So do not need to change uboot at this point.
Pls try this one.
I’ll give it a try this weekend, I won’t be able to test this tonight.
Thanks!
Also - webfailsafe enforces a 16MB limit for all uploads, even NAND despite that being a 128MB flash chip.
This one finally works 
Dont forget to set set fw_setenv boot_dev on !
So this is another bug!
Sorry for necroposting, but that comment should be marked as the solution!
Thanks for sharing!
