QSPI HOLD remains asserted when switching from 1-line to 4-line mode

If I execute all OSPI commands with either DataMode set to HAL_OSPI_DATA_1_LINE or set to HAL_OSPI_DATA_4_LINES then everything behaves as expected. If I first execute a command with DataMode set to HAL_OSPI_DATA_1_LINE, then the Data[3]/HOLD line re...

STM32U585 OSPI hard fault on memory-mapped write

2022-09-12
I'm trying to follow the OSPI_NOR_MemoryMapped STM32CubeIDE example, but for a different device (W25Q128FV). Write Enable, Read Status, and Erase Sector commands behave as expected, as well as memory-mapped reads. This has been confirmed by monitorin...
