Inquiry regarding ARM Cortex-M55 core support

Hello,

I am currently writing a support package for Nuvoton's M55M1 MCU.

I am getting a "ROM Table not found" error when connecting the JTAG adapter.

Here is a link to the code I'm working on:

https://github.com/mymy49/CrossworksForARM_Nuvoton_Mxxx/tree/M55M1_update 

I was expecting it to work without any issues since there is no MMU, but it doesn't.

Please help me.
