Problem & Solution
Synchronisation - Oregano Card Configuration Setup: Unable to Load Modules after an OS upgrade
Problem: There is a mismatch between the version of the of the opalrtlinux folder within the Oregano modules folder and the actual version of opalrt-linux installed. Therefore, when the "oregano_load_module" script is invoked it states that "oregano/1/bin/vX.YYYY-opalrtlinux/ZZZ.ko: No such file or directory." Since the version of opalrt-linux referenced in the aforementioned path does not have a corresponding folder within the oregano modules. Refer to the screenshot below for the error message in MobaXterm.
Solution: The reason for this mismatch is that an OS upgrade was completed on the simulator but the scripts located within the oregano modules folder under RT-LAB and HYPERSIM installations referred to a different version of the OS. To fix this issue, you need to uninstall and then reinstall that specific version of RT-LAB/HYPERSIM so that the simulator will create a new folder within the Oregano Modules for the new OS. After I reinstalled RT-LAB 2023.1 the oregano folder contained the new OS directories (4.19.80 in this case) underneath the ./bin, refer to the screenshot below:
Afterwards, you can execute the oregano_load_module command without issue and the kernels will be up and running, can check this with the lsmod command. Once again, please refer to the screenshot below:
