MIMXRT1064 is used in IAR SDRAM using EWARM IDE.
I am trying to initialize SEMC in the startup routine. There is SEMC_Init after __low_level_init, pin_mux initialization, clock initialization.
Immediately after setting a break and looking at the memory window, the initialization has not been performed and the memory cannot be filled.
On the other hand, if you perform the same initial processing as above in the main, it will succeed.
Is there any missing processing?
Thanks for any help, thank you.
