Hi Paul,
Unfortunately flash programming doesn’t work. It might have seemed that it was
working because the flash was already programmed.
This is the output of flash info 0:

I am not sure what mask to use for the lookup of the rom API table, this is what
I found:

Thank you! Based on this table and your feedback I pushed a new
version to https://review.openocd.org/c/openocd/+/8189 .
Can you please confirm you're getting expected results ("flash info 0"
shows what matches the datasheet, programming works (you should be
able to flash both by -c "program ..." and with "load" command in GDB)
etc?
