Cisco 2802i Access Point LED Flashing Green

We had a Cisco 2802i Access Point that wasn't showing up in the wireless controller.  Upon inspection of the AP hanging on the ceiling, the LED status light was flashing green consistently.

According to Cisco documentation, this indicates a boot loader error.

            

After a little research, I discovered I was going to have to get a ladder and plug in to the console port on the AP.

Once I was connected, I went ahead and tried a factory reset of the AP.  When I saw the CLI of the AP come up, I noticed it was stuck in a "u-boot" prompt.

Further research led me to an article (see source links at the end of this post) that helped me see that the AP had a faulty boot command.

I did a printenv command, and it returned the below (I'm pasting only the first part of the actual output):

             u-boot>> printenv

             BOOT=part1

             CASset=max

             ENABLE_BREAK=1

             FACTORY_RESET=0

             MALLOC_len=5

             MANUAL_BOOT=0

             MEMORY_DEBUG=0

             MPmode=SMP

             autoload=yes

             baudrate=9600

             bootcmd=boardinit

             ...(remaining output omitted)...

This "boardinit" is apparently not the proper bootcmd that the AP should be using.

Here was the proposed solution that worked for me.  I ran the following commands in the u-boot prompt:

            > setenv bootcmd nandboot

      > saveenv

      > boot

Or, it would look like this, for example:

            u-boot>> setenv bootcmd nandboot

       u-boot>> saveenv

         Saving Environment to SPI Flash...

         Erasing SPI flash....Writing to SPI flash.....done

       u-boot>> boot
