Hi to all,
me too have had the same problem upgrading bootloader to 18.104.22.168 and all was fine then upgrading to OS 22.214.171.124 and after reboot the entry RTOS strange instaed of indicating me the relase like the old one it indicate me ROS Linux..... the install 126.96.36.199 bootloader but after the reboot it say Bootloader 188.8.131.52...
I read thorugh the upgrading procedure and it states:
"Cisco recommends that you also install the Cisco Unified Wireless Network Controller Boot Software
184.108.40.206 ER.aes file on the controller. This file resolves defect CSCsd52483 and is necessary to
ensure proper operation of the controller. The ER.aes file can be installed on all controller platforms.
Unlike previous ER images, a new bootloader file is not loaded when you install the 220.127.116.11 ER.aes
file. This is true for all controllers. The 18.104.22.168 ER.aes file is the last ER file to contain a
bootloader. If you want the latest bootloader, install the 22.214.171.124 ER.aes file. If you want to obtain
the fix for CSCsd52483, also install the 126.96.36.199 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 (188.8.131.52
ER.aes), it ensures that the boot software modifications in all of the previous and current boot
software ER.aes files are installed."
so basically it always display the latest bootloader you've it before upgrading to the 184.108.40.206 bootloader which it contains only fix to the bug
