Given below is the step by step procedure to upgrade the uboot version:
1. Download and extract the upgrade archive from the Service & Support website. In addition to the AOS
images, the archive may also contain a Uboot file, for example.
u-boot.5.1R02.1.gz
2. FTP (Binary) the file to the /flash directory on the primary CMM.
3. If desired, a Uboot upgrade can then be performed, for example:
update uboot cmm all file /flash/u-boot.5.1R02.1.gz
Starting CMM ALL UBOOT Upgrade
Please wait...
CMM 1/1
u-boot-ppc_2040.bin: OK
U-boot successfully updated
Successfully updated.
4. Once complete, a reboot is required.
Note: AOS must be upgraded prior to performing a Uboot upgrade.
Yes, very strange.
I have the zip file from MyPortal.
When i unzip i have different *.bin files inside.
I updated OS2260P10 with the u-boot-mips-rtl9300.bin file without issues.
(I checked corresponding chip with "show module long 1")
But with a OS2260P24 it returns:
update uboot cmm all file /flash/u-boot-mips-rtl9300.bin
Starting CMM ALL UBOOT UpgradeERROR:
CMM 1/1 - Update file is not .bin or .tar.gz
