Hi there,I am using STM32F429BIT6 and want to show the SDcard(connect with MCU by SDIO) as a Udisk on PC.I can normally read/write the SD card by MCU with FATFS.But after I added the USB config in CubeMx, the code is something wrong.My CubeMX config ...

Hi there,I am working on STM32F429BIT6, and I have a SD-Card connected.Now, I want to copy some data between the PC and SD-Card by USB directly.Is there any example or document?Anything is welcome, thank you!

Hi there,I am using cubeMx to config the LwIP project which is based on STM32F429BI;I connect the MCU to the route and ping the MCU by PC successfully in DHCP or static IP mode.I can normally get the MCU IPv4 address in static IP mode but fail in DHC...

Hi there,I have a board with STM32F429BI and DM9000(connected to MCU by FMC).I enabled and config the FMC in cubeMx, after that, the LWIP is still gray(can't enable it).Does that mean only when the ETH is configured then the LWIP is useful?If I want ...

Hi there,I have some question about the deferent about the source code and the lib.For example, I have three source code files(func1.c, func2.c, func3.c) and I compiler them to a lib file(func.lib);In my project, I just need use the function in func1...

Hi @FBL Thanks for your reply.Finally I know the reason of mine project.I am compiler the project with MDK compiler V6, this is NOT work for USB_DEVICE source code,after I change to MDK compiler V5, everything is work well.

For MDK IDE, the USB related code must compiled by "MDK compiler V5", the binary by "MDK compiler V6" will NOT work!Demo reference: https://github.com/ShadowThree/STM32V6_extFlash_SDcard_FatFS_Udisk_Demo

Hi, @Tesla DeLorean I have read the example and this tutorial carefully.But my program always can't work, the code is stopped at USBD_GetEpDesc() because pdesc->bDescriptorType always NOT equals to USB_DESC_TYPE_ENDPOINTI am not skillful at USB, but ...

@Tesla DeLorean Thank you for your information!I find a example similar with my requirement at STM32Cube_FW_F4_V1.28.0\Projects\STM32F412G-Discovery\Applications\USB_Device\MSC_Standalone, I will read it carefully.
