XiP & Cortex M4F BSP?

[kiwi]

Is it possible to use XiP in place for RAM as the memory requirements for TCL are 46MB? This microcontroller supports up to 96MB of XIP: https://ambiq.com/wp-content/uploads/2020/10/Apollo3-Blue-Plus-MCU-Datasheet.pdf I was curious of the possibility of using low-power PSRAM to develop the firmware for booting linux with TCL.
