Problems to upgrade CIMC from 2.0(10b) to 3.x or 4.x

[timski]

I am trying to update my CIMC firmware from a Cisco WL5520. When updating the firmware, after a few minutes you will get the following message

"ERROR: Invailed Platform" see screenshot below;

Current CIMC version: C220M4.2.0.10c.0.032320160810

PID: AIR-CT5520-K9
UCS Type: C220M4

Upgrade images used: ucs-c240m4-huu-2.0.13n.iso

ucs-c240m4-huu-3.0.4r.iso and ucs-c240m4-huu-4.1.2g.iso

You are using the wrong file "ucs-c240m4-huu-3.0.", it should be C220 for 5520. If it is 8540 then C240M4 is valid.

Pls refer to below post
