Apparently, it was defined as a design partition (possibly for incremental compile reasons?). I’m not the original designer, so I’m not aware of the design decisions that went into setting that up. I deleted it from design partition table, then I could compile successfully. Would have been nice if tool had indicated “invalid design partition” instead of “internal error”. Regards, Grady

Thanks,
