HelloI'm using the USB CDC class on my STM32H7.Currently, I am using ST's VID (0x0483) and PID (0x5740).I have four questions.1.Can I use ST's VID and PID in our final product version?2.If so, can I redistribute ST's Virtual COM Port driver to our cu...
Hello,i work with STM32G070KBT and i jump from my code to the buitin ST bootloader. Then i use SPI to upload my new code/binary and send the Go command. I receive an ACK but nothing happen. My code is not executet or stops working early.If the bootlo...
I am using STM32Cube_FW_F7_V1.15.0 with a STM32F723IET6 implementing the internal HS USB as device. I have implemented the CDC VCP device. I plug the USB cable into a host computer, running either Windows or linux. If I am running a terminal progr...
Hello, I had problems with setting up HAL_I2C_Mem_Read_DMA() function. Firstly I only defined the Rx DMA channel, but the program was still ending in HardFault_Handler(). After a long debugging I found bug in the "static void I2C_DMAXferCplt(DMA_Hand...
Hello,I'm new to ST. What MPU families does ST have for Cortex-M4F with FreeRTOS and support including demo/eval boards with demo projects, running in IAR, for FreeRTOS? This would include porting and FreeRTOSconfig files etc.?I am especially intere...
Hi guys,I'm experiencing a hard fault error during USB CDC enumeration and can't track its source.The failure occurs in the file usbd_desc.c, when the functon Get_SerialNum() calls a subroutine IntToUnicode() which shall convert an uint32 into its st...
hello everyone Hello to everyone,I have a project where I need to save data on a usb disk and communicate with the computer. I designed a circuit with a type A connector on the usb fs (a11 a12) line and a type b connector on the usb hs (b14 b15) line...
The ST link on the board creates a virtual com port, conected to the LPUSART1 of the micro L4A6ZG.What I´m trying to do is to program the micro throught this com port. To do this, I try this sequence:Put boot0 to high, by shortcircuiting pins 5-7 of...
Hi everybody,I have a weird problem with my STM32F302CC;In my project, HSE can work properly without USB is configured. But when I configure USB, things get weird.In debug mode, the program crash in SystemClock_Config() function when it reaches to ;i...
Hi, I'm not sure if this is the right spot for this question, but here goes. I've just migrated from CMSIS v1 to v2. One of the changes to the API was thread creation. The stack size is now specified in bytes instead of DWORDs. The size is simply di...
