[X440] CPLD update

Thomas D'Hondt

Tue, Mar 25, 2025 10:31 AM

Hello everyone,

I have just successfully updated the filesystem of my Ettus X440 using the dd tool.
I now would like to update the CPLD to the matching version.

Following the X440 user manual, I took a look at the files located in /lib/firmware/ni/ on the X440 file system.
However, I noticed that there are two files that match the X440:

cpld-x440-10m04.rpd
*
cpld-x440-10m08.rpd

As far as I can tell, the manual does not mention the 10m04 and 10m08 variants.

What is the difference between both versions? And which one should I install on my device?

Thanks in advance for your assistance!

Thomas D'hondt

Hi Thomas,

The name indicates that this is for two different versions of the motherboard CPLD. In X410 we have revisions that use the 10m08 CPLD version, so it looks like (for a reason that I could not find out quickly) we generate that for X440, too. However, X440 (until now) only comes with the 10m04 version. If you omit the --file argument, the update script will automatically choose the correct one for you.
