Hi @akaanb ,

If you want to boot with XIP from OCRAM, don't need to include the external RAM in platform designer. The external RAM only included when other boot method is used check this document https://www.intel.com/content/www/us/en/docs/programmable/683689/current/processor-booting-methods.html (page 230 onwards):

Booting from On-Chip Memory (OCRAM):

Make sure onchip memory (OCRAM) is added into your Platform Designer system.

Booting from On-Chip Flash (UFM):

Booting from EPCQ Flash:

Booting from QSPI Flash:

Booting from CFI Flash:

Make sure external RAM or onchip memory (OCRAM) is added into your Platform

Designer system.

Thanks,

Best regards,

Sheng
