With the desired setup built and downloaded, config files downloaded, I've then connected to the PMAC to access the usrflash folder.
From there, I copy the contents into my own flashdrive in a PowerPMAC folder, as the steps in the linked forum post instruct.
To make sure that the PMAC begins in a factory reset state, I issue the '$$$***' command, power off, eject then add the programmed USB, then power on again.
This is where the ProjectLoadErr and PwrOnFault occur, after turning on power with the USB in the PMAC and connecting to the IDE.
In order to see what the flash has programmed the PMAC with, I upload the project from the PMAC.
From here, I will try both building and downloading the project that appears to have been loaded into the IDE, then factory resetting, and opening the archive it has made of the PMAC code and building and downloading that project as well.
(The message that gave me the impression that the project was loaded and opened in the IDE:
)
On attempting to build and download all programs from the code that was opened from the PMAC, this is the message that I receive.
I will then double check by sending the factory reset command.
Next, I will clear the current solution, then open the program in the IDE from the archive that was created earlier.
Now that the PMAC has no program, the old program that was archived is open in the IDE, I now attempt to build and download, which results in the exact same error.
