FTD software on ASA and firmware combability

[Chess Norris]

Hi,

I have upgraded the FTD software on a couple of ASA 5508-X from version 6.3 -> 6.6.0.1

After the upgrade I noticed the following warning message in the CLI.

FPGA UPGRADE Version : 2.4
FPGA GOLDEN Version : unavailable
ROMMON Version : 1.1.13
WARNING: Platform FPGA version is older than minimum recommended image.
WARNING: Platform ROMMON version is older than minimum recommended image.

Is there anywhere I can find information on the minimum required Firmware for FTD 6.6.0.1?

I have looked at the Cisco Firepower combability guide, but cannot find any information there.

Also, after I transferred the firmware, I did a verify on the file, but got some different output.

On the first ASAs, I got this 

verify asa5500-firmware-1118.SPA
Verifying file integrity of disk0:/asa5500-firmware-1118.SPA
Signature Verified

But on the second ASA, I didn't get the "Signature Verified" message. 

However, if I did a SHA-512 check and compared with the file on the first firewall, they matched.

The file should be ok if the SHA-512 checked pass, right?

Thanks

Chess

Any update on this old case? I am getting the same error message after upgrading into 9.12.3 ASA 5516. Did it work properly for you Chess?

UPDATE: Upgrade of firmware completed. No issues.

As long as the hash lookup yields the same result you should be fine. The warning you see is probably because firmware 1.1.15 is recommended for ASA 5508-X since FTD 6.4.0 (see https://www.cisco.com/c/en/us/td/docs/security/firepower/640/relnotes/firepower-release-notes-640/compatibility.html and search for ROMMON for details).

The compatibility guide is quite extensive but it looks like that detail is missing.

Hope that helps!
