Hi , I made a STM32F405VGT6 board with SD card interface. The SD code is generated using STM32CUBEMX and FatFs middleware. The SD file write is not stable, it return error sometimes after calling f_write(). However, if I run the same code in uVis...

We connect STLINK/V2 to STM32G071 with 3 wires : SWDIO, SWCLK and GND. It always failed to connect. However, we can connect by using JLINK. We notice that STM32G071 combines the boot0 with SWCLK. Does this make STLINK/V2 failed to connect ? How can w...

I need to develop a bootloader on STM32L476. So I adapt my code from this tutorial and codes : video https://www.youtube.com/watch?v=OkUQ3iMmiYQ&list=PLnMKNibPkDnEb1sphpdFJ3bR9dNy7S6mO using STM32G071 , However, my adapted code running on STM32L476 a...

It seems there is a mistake in STM32Cube\Repository\STM32Cube_FW_L4_V1.13.0\Projects\STM32L4R9I-EVAL\Examples\OSPI\OSPI_NOR_MemoryMapped project, the STM32L4R9I-EVAL board flash chip is connected in OCTOSPI1, but in this project, the instance is OSPI...

Hi ONadr, Thanks. This did help a lot.Martin

Hi ONadr, Thanks for your prompt reply. Could you explain more about "insufficient blocking of the supply voltage" ？ How can I increase blocking of the supply vpltage ? I can not catch the meaning of "blocking" for supply voltage. Thanks.Martin

Sorry, problem fixed. It is due to a hardware mistake. We put a capacitor instead of pull down resistor for the boot0 signal.

Hi Imen, Thanks a lot for your feedback. I checked AN2606.It is for using bootloader in boot ROM, but I am using open bootloader https://github.com/STMicroelectronics/stm32-mw-openbl. I think there must be something overlooked or mistaken in the ta...

What we need is to enable TouchGFX Designer tool for our STM32L4+ based project. We adopted a 480*272 RGB display.

SD Write error some time , not stable

STLINK/V2 can not work with STM32G071

Is there any major difference between STM32L476 and STM32G071 on the bootloader behavior ?

Is there any AAC or .m4a encoder library ? We need to convert a audio input to a .m4a file
