Hi There,I am working on Mass Storage Class Host implementation using Stm32F105RB controller. I have designed a custom board. I am facing a issue. After connecting USB drive, enumerate operation fails (Function USBH_Get_DevDesc call always fail). I ...
The corresponding UART works fine with HAL_UART_Receive. I've confirmed with GDB that this function fails to return. I realize I'm leaving out a lot of details here, but from the documentation I can see a lot of reasons why this function can *fail*, ...
I am sorry that I am not good at English.Hi. I use the stm32h743zi mcu. I ported stm32h743i-val lwip tcp echo server and client applicationserver application was well working but client was not workingping test was not responed.my firmware flow is th...
Hi,I have two STM32H743II MCUs, one of them is USB device and the other one is the USB host, did it sing the cube.then added to the host code the USBH_CDC_ReceiveCallback function.and added the HAL_PWREx_EnableUSBVoltageDetector(); function after th...
Hello there,I want to load the application code with the bootloader over the RS-485 line using stm32f103 in my project. I did this over the RS-232 line. However, I could not achieve this with the RS-485 line.
So I fought through the growing pains of getting ethernet working on the H7 for a streaming project. So far I've had good luck on the RX side but I'm getting some strange corruption when doing TX load testing.Under a pretty high load I get a corrupte...
