I’ve a AR-300m with older version of uboot so I only see the option to update NAND. How can I upgrade uboot itself and where can I find the necessary files.
Thank you

First, you need to have usb uart adapter, solder the serial pins and setup a tftp server. Can you?
Then I can send you the new uboot and give you the guide.
I have soldered the serial pins and I have a usb uart adapter. Can you please send me the files and guide.
Thank you
I would like a copy as well please…
Can you send me the uboot as well?
also to me if it’s not a problem 
Dear all, uboot attached. use with care.
thank you alzhao, any instructions how to install with usb uart?
setup a tftp server and be able to access uboot console. Rename uboot to uboot-gl-ar300m.bin (check lu command using printenv)
Then use “run lu”
The easiest way to upgrade your u-boot is through web server http://192.168.1.1/uboot.html… just download apropriate u-boot from here http://projects.dymacz.pl/

Hi,
The new bootloader is not working in my router, I have upgraded it and now the router doesnt boot automatically anymore, I have to start manually from command line…
It stops after uboot with this log:

if I type " boot" or “run bootcmd” it start with from NAND else if I type “run blf” it starts from NOR so the nand/nor is not corrupted…
I have reflashed the old bootloader and now it starts corretly again…
I have an ar300m without the 5Ghz wifi,
Thanks,
Guido
OK. I know this reason. Need to find a simple way to fix this. The uboot checks for a testdone flag but in the old firmware there is no. This can be fixed but I need to test first. Please chase me if not come back to you on Tuesday.
I’m also having this issue with the new uboot. Is there a solution for this yet? If not, is there somewhere where I can get the old uboot image so I can flash it back?
I have downloaded the old bootloader from this post:
https://www.gl-inet.com/forums/topic/uboot_for_gl-ar300m-bin-please-can-anyone-upload-it/
Here is a new updated uboot. Please try.
Hi, with the new uboot the router starts every time from NOR…
I have tried:
-
setenv bootcount 0/3–> starts from Nor
-
setenv boot_dev on –> moved the switch left/right –> starts from Nor
Also, if the LAN and the tftp server is up, the uboot enter in infinite loop searching “openwrt-gl-ar300m.bin” file.

Thank you
Reflashed the old uboot and even with this the router now starts every time from nor…
I have tried to flash the nand firmware from uboot web page but the process exit with “error 3”:
////////////////////////
Data will be downloaded at 0x80800000 in RAM
Upgrade type: nand_firmware
Upload file size: 9699328 bytes
Loading: ####…####error 3
////////////////////////
Can you reflash the nand firmware from the uboot UI using a different browser or machine if necessary?
Please use the new uboot to do this.
Ok, reflashed all, uboot, nand firmware and nor firmware.
With the new uboot the flashing process is terminated without errors.
Now, the router starts with Nand, to start fron Nor I must set “fw_setenv bootcount 4”, the “fw_setenv boot_dev on” mode is not working… 
Thank you for your support and time
Guido
@vigans, you are right. boot_dev broken again during bug fix.
