But how can you continue, when mkimage fails and cannot generate the
needed image?

In your patch 2/2 we have this:

+            tools.Run('mkimage', '-d', input_fname, *self._args, output_fname)
+        except Exception as e:
+            tout.Error("mkimage failed: %s" % e)

mkimage is supposed to create an output file which name is in
output_fname; if mkimage fails and you continue, the next step is
tools.ReadFile(output_fname) trying to read that file.  How is this

Best regards,
