Hi experts,
1. We are trying to use MT25QL512ABB this flash. We put it on LP-AM263x and run qspi_flash_diag_am263x demo project and get json file as attachment.

All tests have passed!!
2. We have checked the following settings
- Check for 1s-1s-1s mode (We use 1s mode), WEL have to set 1. - done
- HW reliability : Make sure Micron flash can pass boot qspi_flash_dms_transfer (32KB) & qspi_flash_transfer (256B) test - pass
- To increase your timeout value since SPI mode is much slower - done
3. Please find the final settings we configure.

However, the issues we have encountered so far, we can use flash writer to write image into Micron flash, but we can't boot SBL.
We set QSPI (1S) - Single Read UART Fallback Mode, but after restarting the power supply, SBL fails to start, so start from external host via UART interface.
