hello there!
I use MCIMX6SX4_A9.
I want to clarify some points when qspi boot mode implements.
I realaze that even if an uboot image is created with BOOT_FROM qspi and it will be set at right place on a flash device, there would not be XIP boot process while IVT data structure (entry) points to RAM.
(am i right? i suppose in case of xip, the entry have points to flash address)
i would to know how works the engine that swich load proccess to XIP and is it connected with uboot ld file?
Thank you.
