4 days ago I can see in this file: build_instructions_uhd4p0.md content that indicates that all rfnoc images need to be built using the builder, and are no longer provided as binary images. I believe that answers my question!
The only remaining question is do I always need to update the FPGA using uhd_image_loader, in other words the boot process does not load the binary on power up from a stored config?
In other words, given that I have updated to UHD 4.0, if I want to use the supplied default FPGA, I need to run the uhd_image_loader to update the FPGA (The FPGA firmware is stored in non-volotile memory and is written once?)?
Thank you in advance!!

Issue Description
I am updating a e310 application that uses python uhd, rfnoc images usrp_e310_fpga_RFNOC_sg3.bit. The rfnoc images that are provided, include just the radio_0 block: usrp_e310_sg3_fpga.bit
The GNU radio compile was provided in the ettus binaries for ubuntu UHD installation, and is functioning both with the standard IHD block, and the RFNOC radio block. None of the other blocks are on the FPGA.
On the device, e310, I am running the provided binary image: usrp_e310_fs.sdimg, retrieved by the ubuntu installed UHD 4.0.0 downloader.
If I place new sdcard image in the e310, get the e310 images on the device, do I need to update the FPGA, or does the boot process apply the image at startup? (I forgot how that worked, you can see the FPGA condifuration below).
Do I need to create a new FPGA image using the uhd_image_builder (Vivado 2021.1)?
Setup Details
UHD 4.0.0 Gnuradio 3.10.9.2 Linux Ubuntu 24.02
Expected Behavior
Find usrp_e310_fpga_RFNOC_sg3.bit in the images database.
Actual Behaviour

Steps to reproduce the problem
Create an UHD e310 sdimage, boot the device, get the fpga images using uhd_images_downloader (on the device, or on host) use -n -t "RFNOC", no RFNOC images are present.
