This did not seem to fix it

Here is some output from the toofow run, not sure if it's helpful

Did this get completed in the end?

@jack-h As I understand it, this is not yet ready for merge.

@kiranshila can you confirm this is still WIP / convert to draft?

[kiranshila]

Yeah iirc I still had issues after all these changes - I was reasonably sure I needed to rebuild the JAM image but ran into too many problems even to start.

This should now be addressed in the m2021a-dev branch. @liuweiseu made similar changes and found it to work.

Leaving this open for the moment until we're sure all issues are addressed, but hopefully we can now close it.
