Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Hello,We have random HardFaults on an STM32H750, maybe after several hours of uptime.It seems caused by an access to a wrong RAM location, whose address is fetched from the stack and stored in r2.But the stack seems OK.This happens in a function freq...
hi,I make bootloader to switch the code between two bank starting at address 0x08000000.and two application starting at 0x08020000 and 0x08100000 respectively, when I individual run the code it work fine, but when I hard reset the code, it goes to bo...
Hi, I'm trying to setup a stm32g070kb (32pin) MCU as I2C slave by using CubeIDE.I would like to create a code which will work same as I2C Eeprom, but when I ask the stm32 (with another MCU) to return me a register or registers value, the returned reg...
Hey all,I would like to make a HID device which would have output options configured by computer, I thought I would use same USB to feed the config to STM, But I cant seem to find a clear answer if it is even possible to send data to USB HID, like yo...
This post is a constructive feedback channel for the STM32C0316-DK Brisk demo project.Implemented Application Functions:Alternative IO Drivers which can coexist with HAL'sSTM32 Vdd and Temperature monitoringAnalog Keyboard (ADC, Debouncing)LEDs (puls...
Hi! I'm in a conundrum, and am wondering if there are hacks around this. I'd like to use CAN on a a G4. And give it updatable firmware by USB. My options appear to be this:#1: Share a CAN Rx line with Boot 0 pin.#2 Share CAN Rx line with USP_DN.Are e...
Hello,I am trying to restart a STM32L072 into DFU bootloader mode (using STM32 LoRa Discovery kit) .The bootloader is working and I can use it to flash my firmware using a jumper between BOOT0 and VCC.Now I would like to enter bootloader from source....
HAL_ETH_ReadData() reported bufflength 60 bytes (damrxdesc-> DESC0.FL shows 64 bytes. looking at the code, bufflength is derived from DESC0.FL - 4. ). However wireshark shows the incoming frame is TCP ACK with no data. So it should be 54 bytes, and ...
I am trying to run a USB HS example with external PHY on NUCLEO-F756ZG. As I count find example I have gone ahead and created code from scratch. I am using USB3300 external PHY. I have made the proper connection except for RST and +5V to the module b...
I've seen many topics similar to my problem and went through their solutions but they didn't work for me so I'm asking here with details related to my problem. I've made a PCB and implemented USB 2 FS on it using STM32F407 PHY in device mode. here is...
