How to switch usrp_b210_fpga.bin image in the docker compose image? (LibreSDR USRP B210)

[arasakatyler]

I'm trying to run the 5G COTS UE via the docker container instead of the normal way as I can't get my devices to connect or see the 5G network. Someone suggested trying the docker container.

I've ran into another problem, when I go to "docker compose up" It gets to the "srsran_gnb" area and trys to load the original fpga for B210 from /opt/uhd/4.7.0.0/share/uhd/images/usrp_b210_fpga.bin

I have a LibreSDR B210, and it comes with a customer "usrp_b210_fpga.bin" image, usually I can just go to the /uhd/share/images folder on the host machine for example, or docker container and replace the original fpga.bin file and add the custom one to the folder and everything works fine... when I do "uhd_usrp_probe" but in this situation I can't seem to find the folder location with this docker compose image or containers.

Running "docker ps" I can see the containers running when I launch docker compose up, but I don't see the srsran_gnb container (which i presume is the one with this folder location)

I accessed all the other containers and searched for opt/uhd/4.7.0.0/share/uhd/images/ but can't find the folder anywhere.

How can I manually add my custom fpga image to the docker container?

I just got LibreSDR B220 (The variant with larger FPGA)today. I can use it in normal way without using docker. However, I have 2 UEs, Samsung A33 5G and Samsung A53 5G. Both of them work just fine with Ettus B210. However, only Samsung A33 5G works when I using internal clock. I have to connect to Leo bodnar GPSO to get Samsung A53 5G works. Both of them are working now for hours. One last thing, it even works without Leo bodnar locking to GPS. (I just disconnect the GPS antenna). It seems that it just need a good TCXO clock. You may need to try another UEs or just find a good 10MHz ref clock.
