Hello,
I generated a project for STM32U5A9J-DK with STM32CubeIDE (v1.16.0). It doesn’t include the OctalFlash test code. So, I used the test codes in chapter "Octo-SPI FLASH in Regular-command protocol example" of attached AN5050.
The mounted OctalFlash is MX25UM51245G. With the program, the data output was shifted by one byte as below.
After I use the HAL_OSPI_DELAY_BLOCK, the pass rate becomes higher but still fails. Please help.
Thanks.
