WLC Bootloader

wynneit — Sat, 03 Jul 2021 23:32:08 GMT

A while since I upgrded a controller to anything but 4.1.171 however I notice a lack of a bootloader image on the latest WLC software. What happened to it or am I looking in the wrong place.

Apologies for all the questions trying to catch up

Also its a great forum and I appreciate all your input

Hey Pete,

Here is a good clip;

Unlike previous ER images, a new bootloader file is not loaded when you install the 5.0.148.0 ER.aes file. This is true for all controllers. The 4.2.112.0 ER.aes file is the last ER file to contain a bootloader. If you want the latest bootloader, install the 4.2.112.0 ER.aes file. If you want to obtain the fix for CSCsd52483, also install the 5.0.148.0 ER.aes file.

The ER.aes files are independent from the controller software files. You can run any controller software file with any ER.aes file, but when you install the latest boot software file (5.0.148.0 ER.aes), it ensures that the boot software modifications in all of the previous and current boot software ER.aes files are installed.

Hope this helps!
