Hello,We are currently working on a USB type C based fast charging system design and interfacing STUSB4500 with MSP430G2553 to compliant PD for fast charging. We are successfully able to read and write registers through I2C.So Is it require to implem...
So i am writing an application to communicate with STM32 internal bootloader.Everything works fine except writing to flash of L031 nucleo board (it works with F303 nucleo board).It even works normally if my writes are page aligned.Ok so problem is wh...
When using devices that cannot be identified by ClassCode (0xFF) you have to hack usbh_core.c on the HOST_CHECK_CLASS handling and rather filter on the idVendor/idProduct. I found a better way to handle it (much cleaner) registering some class with ...
Hello,we want to program the MCU STM32L432 in our final product via USB-Interface, mainly in order to save pins due to limitid space.Assuming we have a brand new microprocessor:Refering to the reference manual RM0394 p. 74 and application note AN2606...
Hey there,since a few weeks i am setting up a USB-PD sink with the Nuc-USBPDM1 and Nuc-G474.In this special case i want to:1. Read out charger PDOs2. Set up Fixed PDOs (e.g. 15V@3A) and switching during runtime3. Set up APDOs according to PPS (variab...
I am trying to reprogram a custom board with STM32F411RC over I2C using the built-in bootloader. I am able to successfully issue the Get version, Get ID and Get command and get correct response. After that when I try to do a No-streach mass erase (da...
Hello ST Community,I'm planning to use the USB communication with a STM32H743ZI. Then, I will have to use an external power supply, since it doesn't have VDD50USB input. Furtherore, I will power this MCU with a 3.3Vcc. power supply.However, I read in...
Dear everyone,I am using Nucleo-F767ZI + FreeRTOS + LWIP + mbedtls generated my STM32CubeMX (latest version). When I use my code to connect and send data to www.google.com using HTTPS, everything works fine, however when the same code is used to conn...
Hello,I am using a STM32L432KC to control the UART bootloader of a STM32F446RE.First, I am sending Get and Get ID command to check if I get the recquired answer. It works, but not as I wish.To begin I Initialize the bootloader sending 0x7F and that w...
