Alcatel Unleashed

When upgrading the alcatel firmware, is there a version that must be installed as a minimum?
If you are using a version lower than the version guided in the Minimum U-Boot section in the release note, please let us know if you need to upgrade sequentially

equipment version
OS6860-P24 : 8.1.1.689.R01

upgrade version
OmniSwitch 6860(E) – AOS Release 8.7.252.R02 (GA)

release note
OS6860/OS6860E
(except U28/P24Z8)
Minimum U-Boot : 8.1.1.70.R01


please answer about my question.
thank you.

Solved.
By mistake, the u-boot version was 8.1.1.70.R01.
