MSC USB not working with TCP stack
Hello,I am working on the customized board with MCU STM32F767 + + LAN8742A + freeRTOS. The USB MSC host was working if no TCP server code was added. But when I add the TCP code, MSC is not working any more.The code is as below:if tcpip_init(NULL, NU...
'F09x - empty flag is not handled by bootloader as advertized
STM32F09x, when upon power-on reset it's FLASH is empty (which is a bit of an overstatement, it acutally checks only if 0x08000000 is 0xFFFFFFFF), it behaves as if BOOT0 is 1, i.e. maps system memory onto 0x00000000 and starts there. So far so good, ...
SW4STM STM32F0 changing program start address in flash.
Hi,I'm developing bootloader on NUCLEO-F072RB board. I have ready bootloader code to jump for user application placed on specified address.Now I'm writing this application so I'm changing this line in STM32F072RBTx_FLASH.ld fileFLASH (rx) : ORIGIN...

STM32F4x9 Eval USBD bulk in transmit problem
Hi ,I'm using STM32F4x9 eval board with STM32Cube v1.24 library on USB device parctice.Refer to CDC example, a new SCAN device class was created and enumerated succcess.Sending data from PC host site (Bulk Out) can success to get in device (STM32 - v...
Resolved! What is the differences between "EXTI_Callback" and "EXTI_IRQHandler"?
In the sample code, STM uses "HAL_GPIO_EXTI_Callback" to handle interrupt from a push button, but in class I learnt that we need to use the IRQHandler to handle the interrupt. When to use "HAL_GPIO_EXTI_Callback" and "HAL_GPIO_EXTI_IRQHandler" to han...
Resolved! Possible bug in STM32Cube_FW_H7_V1.5.0 SystemInit() function
Hello,I have been having problems with my debugger losing connection when i set the CM7 of my STM32H745 into CSleep mode. I have the DBGMCU flags set to enable debugging in low power, but I assumed I was still doing something incorrect with the domai...
MSC USB Host very slow usb stick recognition
Hi, I'm using a STM32F429 with usb host connected to FS.Using the official USB MSC Host library from ST (1.24.1 latest one) I have a slow recognition when I insert a USB stick.The callback USBH_UserProcess with HOST_USER_CLASS_ACTIVE event, so after ...
