STM32CubeL4 v1.17.1 OSPI Delay Block Bypass Problem

The latest versions of the STM32CubeL4 drivers (1.17.1) and CubeMX (6.5.0) introduce two bugs related to the OSPI and Delay Block Bypass.

  1. In stm32l4xx_hal_ospi.c line 383, the MODIFY_REG macro no long clears the DLYBYP bit. It also fails to set it according to the CubeMX configuration. I don't understand why these were removed.
  2. The CubeMX setting is using inverse logic. The setting is labeled Delay Block Bypass. Thus, Enable should indicate the bypass is enabled (HAL_OSPI_DELAY_BLOCK_BYPASSED), whereas Disable should mean disabling the bypass (HAL_OSPI_DELAY_BLOCK_USED). However, CubeMX reverses these values.

Hello @ebray​,

For the first point regarding the stm32l4xx_hal_ospi.c, I confirm the issue, an internal ticket is submitted, it will be corrected with the future release.

PS: Internal ticket 121187. This is an internal tracking number and is not accessible or usable by customers.

For the second point concerning the STM32CubeMX, I will let @Sara BEN HADJ YAHYA​ check it.

Thank you.
