STM32G4 USBD CMSIS Driver
Is there STM32G4 USBD CMSIS Driver? Because latest (1.5.0) package for G4 doesnt include it. There is an example for CDC, but nothing for CMSIS and RTOS. Seems kinda weird.

FATFS f_open fails when data cache is enabled
When enabled Data cache for example in main:/* Enable D-Cache---------------------------------------------------------*/ SCB_EnableDCache();I think I am supposed to uncomment L63 in sd_diskio.c to activate Cache maintenance:/* USER CODE BEGIN enabl...
ETH_DMACSR_RBU error occurs and stalls the Ethernet receive on STM32H7. Is there a way around this issue with the DMA?
Hi, I've been using the STM32H7 example which uses the new reworked Ethernet driver (https://github.com/STMicroelectronics/STM32CubeH7). Changed the application layer of the example (LwIP_HTTP_Server_Netconn_RTOS) and during larger transfers, the DMA...
Ethernet communication - mx_lwip_process() how often
Hi everyone,I am using STM32f429, and I am using Ethernet communication.Inside the while(1) has the mx_lwip_process() function and I am using the function every while, and I found this function takes a lot of time, so I would like to know how often I...
ethernetif_set_link thread is not running. I would like to detect link up or down. I am using STM32F429ZIT6 - Nucleo, FreeRTOS CMSIS v1, LWIP v2.1.2 I am able to break in "tcpip_thread" so I assume it's not a scheduler issue. Anybody has an Idea?

Using DAC1_2 with SDRAM and HS USB PHY
Is this possible - even in a hacky way.the OPAMP2_VOUT (PE7 follower) output clashes with FMC_D4+the DAC1_OUT2 pin (PA5) clashes with USB HS ULPI CKSo is any configuration possible where DAC1_2, USB HS and SDRAM can work together?
Resolved! Can I use backup registers when RTC is disabled?
I need the RTC module to be enabled in order to write to & read from backup registers on STM32F401 using these functions:void HAL_RTCEx_BKUPWrite(RTC_HandleTypeDef *hrtc, uint32_t BackupRegister, uint32_t Data) uint32_t HAL_RTCEx_BKUPRead(RTC_HandleT...
STM32H747-DISCO (CM7 Used RTOS for Graphics, UART8) (CM4 Used for Tim1 PWM,SDMMI with FAT_M4.)
STM32H747-Disco, Cube IDE 1.10.1I've designed a UI using the method of MPV a few times in the past using one processor(CM7). Now, I'm using CM4 for sd card and PWM, I can't seem to get the model.cpp to recognize TIM1 handler (htmi1). I had made a s...
Resolved! Using osDelay(1) and HAL_ADC_PollForConversion with 0 timeout in FreeRTOS environment.
Hi,I'm using the NUCLEO-64 STM32L476RG and I am aware that it is very simple to start the ADC to get a reading in an analog port. One should however wait for the conversion to complete and the HAL library has the HAL_ADC_PollForConversion() function ...
Using bootloader GO command with BOOT0 always asserted
I am using the I2C bootloader on STM32L431, in a system where another host CPU exists. I would like to minimize the number of host GPIO needed to manage entry to bootloader mode. (Currently the host is controlling the BOOT0 and RST# pins). I would...
