AM623: Flash device IO Test Error

Tool/software:

The test of the FlashROM connected to the custom board does not pass.
Custom board with AM62 mounted is now booted in SD boot mode.

The sample project of OSPI_FLASH_IO was modified.
Test passed for 1S-1S-1S, but cannot pass for 4S-4S-4S protocol.
I think there is a problem with the settings on Sysconfig, but I don't know what the problem is.

【Device Information】
・CPU：AM6234ATCGHAALW
・FlashROM：MT25QL256ABA8ESF
　-256Mbit
　-Quad SPI

I had already inquired about this, but I would like to make a new inquiry.
