mimxrt595_evk flexspi2(memc) cannot work properly

[KATE-WANG-NXP]

Describe the bug

Display sample does not work correctly on RT500 for shield rk055hdmipi4ma0 when the frame buffer is placed on FLEXSPI2.
Build and run the example:
west build -p always -b mimxrt595_evk/mimxrt595s/cm33 samples/drivers/display -d test_rt500 --shield rk055hdmipi4ma0
The program never run to main and the panel is blank
However if changing the CONFIG_MCUX_DCNANO_LCDIF_EXTERNAL_FB_MEM=n in boards\shields\rk055hdmipi4ma0\boards\mimxrt595_evk_mimxrt595s_cm33.conf which means the frame buffers placed on RAM and CONFIG_MCUX_DCNANO_LCDIF_EXTERNAL_FB_ADDR=0x38400000 will not be used with CONFIG_MEMC=n, the demo works as expected.

Regression

• This is a regression.

Steps to reproduce

1. Build and run the example:
   west build -p always -b mimxrt595_evk/mimxrt595s/cm33 samples/drivers/display -d test_rt500 --shield rk055hdmipi4ma0
   The program never run to main and the panel is blank
2. Change the CONFIG_MCUX_DCNANO_LCDIF_EXTERNAL_FB_MEM=n in boards\shields\rk055hdmipi4ma0\boards\mimxrt595_evk_mimxrt595s_cm33.conf , the demo works as expected.
