Hi everyone!I'm working on USB MSC implementation on STM32U0 series MCU with W25Q32JV (NOR Flash) by using USBX + ThreadX.W25Q32 Memory organization:- It has 64 blocks and each block is of size 64KB- Each block has 16 sectors and each sector is of si...

Hello,I'm working on a project which includes: W25Q32 (NOR Flash), File system and USB MSC + CDC on STM32U0 series MCU - STM32U073RCT6.Till now, I've implemented these:- SPI setup and communication with the NOR Flash (W25Q32)- For the file-system par...

I'm using STM32U073MCT6 MCU. I have a custom board (which contains this MCU and other required components) and I have 4 stages in my data logger that I want to develop using this board:1) Just the battery is soldered and trip isn't started2) Trip sta...

I'm using STM32U083C-DK which contains STM32U083MCT6 MCU. I want to use W25Q32 NOR Flash using standard SPI protocol. For implementing the file system, for my MCU -> Middleware doesn't have FATFS instead it has FileX, LevelX and ThreadX. I couldn't f...

I'm using STM32U083C-DK which has STM32U083MCT6 MCU. And I have an external NOR Flash memory: W25Q32JVSSIQ.I've implemented the SPI communication with the Flash memory and able to reset, read the device ID and do basic Flash memory operations such as...

Hi @carlogulliani Could you please share the code for this? I'm working on same but w25q32 and STM32U0 series MCU. It would be very helpful if you could share the code so that I can use that as a reference.Regards,Bharath

Hi @Mr_Ducer Did you sort out how to handle NOR Flash read operation in USBD_STORAGE_Read?

Hi @Haithem Rahmani But when I created a file system using FatFS library (not FileX + LevelX), it is created and mounted successfully. But because of the size of this NOR Flash i.e 4MB, the FatFS library function "ff.c" is automatically choosing Fat1...

Hi @Pepils Can you please provide with the code and .ioc file for the NOR Flash part i.e "USBX MSC + FileX + NOR Flash"?Thank you

Hey!If you see the code, before entering into the Stop2 mode itself the debugger is getting stuck at 'MX_GPIO_Init()' and showing the error "Target not responding, retrying..."And yeah, I enabled to debug in low power modes as well.
