QSPI driver for STM32U5G9 under ThreadX

Hi,I would like to know if you have some examples to implement a QSPI driver under ThreadX for a STM32U5G9? According to my readings, LevelX seems to be appropriate (I am not sure) because we need to implement some basic functionalities (read, writ...

how to write in QSPI flash while in xip mode with FreeRTOS

Hello,I am trying to do an OTA upgrade on my STM32H750. I am using QSPI flash in dual mode as the IC does not have so much internal flash for my application. My application is running FreeRTOS and does have a LCD screen. So I build a bootloader to co...

STM32H QSPI LL Driver

Hello,I'm trying to implement the QSPI interface to a micron device utilizing the OSPI hardware with LL kinda of driver (It's not available so I tried to write it by myself). I configured the OSPI and OSPIM registers and from signals that I see on my...

STM32H7 Race condition in HAL_QSPI_Transmit_DMA with MCU package 1.11.0

We noticed that there is a race condition in the function HAL_QSPI_Transmit_DMA in the following code:/* Enable the QSPI transmit MDMA */ if (HAL_MDMA_Start_IT(hqspi->hmdma, (uint32_t)pData, (uint32_t)&hqspi->Instance->DR, hqspi->TxXferSize, 1) == HA...

Is OpenBootloader a good starting point for DFU on STM32H750 with RS485 and QSPI NOR?

We need a DFU-capable bootloader for a custom board based on the STM32H750.We can't use the ROM bootloader due to 2 requirements:upload of the DFU image needs to happen over RS-485, with support for DE to an external transceiverwe need to flash the D...

Resolved! STM32H7 Write to QSPI using Filex and Levelx. Issue at fx_media_format.

Hi,I am using the STM32H747I-DISCO and wanting to write to the QSPI using Filex. I tried using the example FX_Dual_Instance, but could not get this working. Since then I have built a project step by step using the CubeMx initialization tool. Both tim...
