AM6442: SBL support NOR Flash 256MB

Part Number: AM6442

Hello TI's Expert.

1. My product is designed to use S28HL02GT (256MB) on AM6442 board

I saw the file flash_nor_ospi_quad_device_S25HL512T.c in the MCU SKD but i don't know exactly if I need to change the information in this file to support 256MB nor-flash?

Please give me the suggestion.

2. I use 512MB DDR on my board, the SBL needs to update the content of file board_ddrReginit.h by syscfg tool. Is it right?

3. I want to debug the SBL on CCS tool, but I don't know how to do it at the first boot stage. Can you show me how to do it because  I need to debug DDR_init step by setp.

Thank you so much,
