Resolved! STM32F4x HAL_ETH_ReadPHYRegister blocking mode
Dear allAfter having enabled ETH + LwIP stack we are experiencing that something in the init phase are keeping blocked all.After a while we see that the root causes is inside HAL_ETH_ReadPHYRegister.Specifically we are referring at this part of code:...
LWIP / 32F417 - how to optimise network stack memory allocation?
This project was set up by someone else. It uses the ST port of LWIP and FreeRTOS.I have spent hours googling on this. As usual one digs up a vast number of forum and usenet posts, mostly with no clear conclusions. Some people are trying to optimise ...
Resolved! Why USB_ResetPort function has 100 ms delay ?
USB_ResetPort function is called in USBH_Process in HOST_IDLE state after USBH_Delay(200U); this results in 300 ms delay usb application.Is there any way to reduce this time in stm32 USB applications.This function is after a USB connection. Is there ...
Resolved! STM32F750 + USB Host + FATFS return FR_DISK_ERR
Hi, I'm trying to run a USB host mass storage on an STM32F750. After building the project in STM32Cube V 1.11.0 I have in "usb_host.c" after the line" Appli_state = APPLICATION_READY;" the code "res = f_mount(&USBHFatFS, USBHPath, 1);" written, but "...
Resolved! STM32H7: New HAL and PBUF_POOL usage
Hi all,I am developing an application using bare TCP and UDP connections.Since the new HAL implementation now uses custom PBuf allocation for Rx memories, I thought about killing the PBUF_POOL since it does not seem to be used anymore now.I started b...
STM32L4 HAL UART DMA does not recover after error
The exact issue I am experiencing with the STM32L4 series (both L476 and L412), is described here: https://stackoverflow.com/a/71297149/10909834The solution I came to independently is to reinitialize the uart. I used HAL_UART_DeInit() followed by HAL...
Unable to close files in STM32 with USB MSC + FATFS
I created a project to create, write, read and close a file in a USB stick, using a STM32F413 MCU. I used STM32CubeMX to generate the code. The relevant part of the code is this: uint8_t text[]={"Hello world\r\n"},rbuff[50],test=0; switch(Appli_sta...
