I have a UDP socket for sending and receiving messages. Everything works fine for packets up to a certain size. I see via 'Wireshark' that I can successfully receive packets that get fragmented into at most 4 fragments.These are the parameters that I...
I'm using STM32F405RGT6 as a Main controller on the board for our product.When we flash the FW to STM32F405RGT6 via FT232RL, it fails to enter bootloader mode sometimes. Failling rate is around 40-50%. I observed signal behaviour about Reset(DTR) and...
Hello,I want to use USB-Host MSC with FreeRTOS on a STM32H745.When I generate a project in CubeIDE (with integrated CubeMX) without FreeRTOS and add the few need lines (like the example from ControllersTech on YouTube) it works fine on a Nucleo-H745....
I need to develop a bootloader on STM32L476. So I adapt my code from this tutorial and codes : video https://www.youtube.com/watch?v=OkUQ3iMmiYQ&list=PLnMKNibPkDnEb1sphpdFJ3bR9dNy7S6mO using STM32G071 , However, my adapted code running on STM32L476 a...
The STM32F4 Discovery board docs state that "When connected to a PC with a second USB Type-A to USB Type-C to Micro-B cable through CN5, the board is recognized as a standard mouse".This is confusing, Type-A to Type-C to Micro-B, what can that mean?A...
Hi, I want to change my Controller from the F3 to the U5 (more RAM and Flash needed and the U5 LQFP48 is 98% pin compatible)Only Problem: The application is ready to use on the F3, I want to port it to the U5 but the U5 supports USB only with Azure R...
We have a new project and would like it to have some features similar to the STM32 on an STLink:a) Emulate a Thumbdrive using MCU FLASH and/or an external serial FLASH IC. The files should be accessible by both the STM32 and any PC connected to the U...

The HAL L4 page 38 - but I saw it more also in other doc - has an error how to use HAL_GetTick for timeout:HAL_StatusTypeDef HAL_PPP_Process(PPP_HandleTypeDef)timeout = HAL_GetTick() + LOCAL_PROCESS_TIMEOUT;while(ProcessOngoing)if (HAL_GetTick() ≥ ti...
USB DP and DM have no 1.5k pull-up resistance, which will not take effect after internal pull-up of DP or DM (DP or DM grounded), and the resistance value of current limiting resistance (R56 R58) is 12.5 Ω instead of the marked 22 ΩThe measured value...
