What is "USB_CRS_SYNC" functionality?
Could you please explain to me "USB_CRS_SYNC" functionality? And, is it necessary to be used with "USB_DM" and "USB_DP" please?

STM32H7 Ethernet CurrentDescriptor vs ETH_TX_DESC_CNT
As I understand from the low_level_output of ethernetif.c, I could have up to the number of ETH_TX_DESC_CNT of buffers.In the stm32h7xx_hal_eth.c ETH_Prepare_Tx_Descriptors (not counting the context descriptors) I "upload" the buffers to the Descript...
Lwip TCP Client disconnect detection. I am unable to detect if my client is disconnected from server. if my server sends the close command then i am able to detect but problem arises when the server stops abruptly or power goes down.
MCU is STM32F207VIT6 (client)server is windows application.LWIP library is used.Is there any ping command?
jump to another app explanation
I have this code:void bootloader_jump_to_app(void){ pFunction Jump; uint32_t JumpAddress; HAL_RCC_DeInit(); HAL_DeInit(); JumpAddress = *(__IO uint32_t*)(APP_ADDRESS + 4); Jump = (pFunction)JumpAddress; __set_MSP(*(__IO uint32_t*)APP_AD...
How do I get independent stereo audio output on STM32F469I-DISCO board?
I am having trouble getting independent stereo audio output on the STM32F469I-DISCO development board. I am passing data to the cirrus audio codec using the stm32469i_discovery_audio.h functions:BSP_AUDIO_OUT_Init(OUTPUT_DEVICE_BOTH, 80, 48);BSP_AUDI...
Resolved! Project with own bootloader goes into "b Infinite_Loop" when an timer interrupt occure.
Hi,i have written a custom bootloader + end user application for STM32G030K8.When i run the bootloader seperately , then the bootload code works as expectedWhen i run the user application from addres 0x0800000 then the code works fine.But after i mak...
Resolved! STM32H747I-DISCO working Ethernet example project
Hi all,I would like to create a STM32CubeIDE project for my H747 discovery board. I've modified the board (rerouting to the ethernet IC) as the guide propose and the it is working (I tried out with MBED OS socket example). But in the ST IDE there isn...
Missing HardFault_IRQn values in CubeF4 v1.26.2 and CubeF7 v1.16.1 and 1.16.2
CubeF4 version 1.26.2 and CubeF7 version 1.16.1 and 1.16.2 are missing the enum value for HardFault_IRQn in all of the device specific include files (ex. stm32f429xx.h and stm32f746xx.h). It may be missing in earlier versions, I did not check. Cube...
Issue using the HAL internal flash memory interface when leveraging a bootloader and firmware memory structure.
I am currently using an STM32L452 MCU that operates using a custom bootloader and firmware package for operation. I have leveraged the bootloader on other projects before, so I knew (or at least thought i knew) it was solid. I'm learning that when i ...
SD Card not mounted and returns FR_DISK_ERR when put in a FREERTOS task.
I am using STM32H7, FatFS, FreeRTOS to write/read from an SD Card (SDMMC), it was working fine before I implemented FreeRTOS but after I did , it started returning this error when mounting the SD Card.Attached is my code and initialization related to...
