Firepower 2100 boot directly to Rommon

I have a pair of Cisco 2100 series firepower devices that I am configuring for deployment at two separate locations. Currently when powered on, they go into rommon, without any prompt from me. Once I type the boot command they will complete their boot process and allow configuration through the Firepower GUI. As these will be at remote sites, I need them to boot fully without user input.

The bug report linked solved my issue, though I find it weird as these are fresh from the box appliances.

 - Did you examine the confreg value the device was shipped with , (as explained in the bug-report) ?

 M.

It was set to 0x0. I went through the prompts of the confreg command and the value had changed to 0x1 when I was done. I did not see this step in any startup guide, so just a bit annoyed that this was buried so deeply in Cisco's documentation.

 

          - Yeah it stunned me too , that I could not  find this rather quick with searching.

 M.

Yes, I've been seeing it on multiple 2100 series this year. It's a change from previous behavior and definitely, as the bugID indicates, not how it should work.

The "confreg 0x1" command fixes it permanently. I had answered a similar thread a couple of weeks ago:
