Phil,
First...are you following the BPS porting guide????
Yes, it's a pain in the ass following it step by step, but it will pay off in the long run. There are some hints in there also about RZ/A1H vs RZ/A1L.

You don't need that anymore (if you pull from github). A couple weeks ago I added in all the I/O for RZ/A1L so now everything is supported.

Are you using SCIF2 like the RSK board? If not, you'll need to make some adjustments (see the porting guide).
Are you doing XIP? If so, then maybe you need to fist make sure your QSPI is set up correctly for XIP mode....otherwise you code will crash right off the bat.
> Do you have a board file for the RZ/A1L?
That's not really needed. The peripherals are the same, and at the same register address. Like the porting guide says..you just need to go through and delete the stuff you are not using. A couple peripherals come out on different port numbers on the RZ/A1L...but that's about it.
