Get early access to the next-generation STM32Cube HAL drivers for STM32U5A major update to STM32Cube HAL drivers, called HAL2, is now available for preview on GitHub. It supports the STM32U5 series. Building on over 10 years of experience, HAL2 deliv...
When my STM32G0B1KET receives an Discover SVIDs message, it responds GOODCRC, then the core library function PE_StateMachine_VDM() calls the reset handler. After reset the system hardfaults. System responds to discover identity properly. The USBPD_VD...
I am porting code from STM32L4R5 (STM32L4R5VIT6) to STM32H743 (STM32H743VIT6). All the porting has gone well except for the last part being Bootloader. We use Boot0 pin Grounded and request to go to bootloader within the application. I should also me...
I'm working on a setup with a STM32L452RE and want to use the USB as a CDC-Device. I want to use the internal PullUp for D+ and the VBUS-sensing. I only find very unspecific Information about what i got to do in software. Also which Pin to use (proba...
I read some related topics on this community but none of them could fixes the issue.I'm currently trying to disable a USB OUT endpoint (following the steps from the Reference Manual) but the Global NAK Effective interrupt bit (GONAKEFF in USB_OTG_FS_...
The CSTF bit definition for ETH_MACCR register is missing from all CMSIS header definition files for F7, F4 and F2 series MCUs with ETH peripheral. F1 series doesn't have this bit or at least it isn't documented in the reference manual. I guess for F...
Hi,I am looking to use the STM32U575CIT6Q in a USB project. The documentation everywhere mentions VDDUSB but that pin does not appear to be present on the LQFP48 package. Is it just tied to VDD internally? The data sheet appears to show that OTG F...
Hi, Why the task keep running and remain of infinite loop, and do not enter another function ?
I am using 9600 baud rate and even parity .Address bytes sent with checksum is 08 00 00 00 08 ACK Received
Hi,I'm having a STM32G474 with Bootloader block (0x0800 0000 - 0x0800 4FFF) and Application block (0x0800 5000 - 0x0807 FFFF).I need to update Bootloader from Application, by copying a new bootloader located on higher memory. Is it possible ?I'm usin...
Hi, I have to develope a system where an stm32 connected via ethernet handles files stored in a sdcard through an FTP connection from a PC.I know there is a sample from ST exactly about this but I can't get it to work on my nucleo H723 board, it seem...
