IIRC, the "remap" does not apply to the TCM. So you need to tell the
core to place TCM at 0 and its size, after this tell the MPU
(peripheral) about the TCM mapping. Now you should see TCM at 0.

But I guess switching should be done outside this area.

Note: Since TCM is TC :-) it is not due to MMU mapping and will overlay
any memory at this place.
