From what I understand, this particular image only creates a RAM image that we subsequently use for our own purposes. The 3.3 PSoC creator gave no errors, only the 4.x is giving errors.
Follow-on question: is there a way to SKIP cyelftool for a given project ? This is under Windows, PSoC Creator 4.x
I haven't met this issue.
But sometimes this kind of issue caused by some invalid configuration of tool chains.
Could you share the full project, so that we can try reproducing the error and try to find workaround?
