Hello, I am working on the ST STM32H747I Discovery and I have a question regarding Ethernet. According to the ST documentation (https://www.st.com/resource/en/user_manual/dm00504240.pdf), some hardware modification is mandatory to manage Ethernet. Ho...
I have a USB HID device based on the STM32L432 that I inherited maintenance on. My particular device has a HID Report Descriptor that is greater than 64 bytes. I'm debugging using an ST-Link and single-stepping, trying to figure out how the code hand...
for MCU time is very important to do task.in programming instead of blocking time of MCU we can do other important task how can i do in c programming language?ex: HAL_Delay(); block code execution vest of MCU time.while() waiting for sensor IP etc....
I made a firmware download project using a factory bootloader according to AN4286. Everything works fine. I have only one ambiguity - in the description of the bootloader in AN2606 there is a picture on which the SCK signal is pulled-down to the grou...
We are using STM32F469VI for developing a device which uses the following peripherals:GPIOUART (probably around 3 of them)SDIO (SD card in device, requiring FatFS access as well as mass storage via USB, see below)USB (2 ports)I2CWe would like to conf...
Hi all,we're planing to use an STM32H742 with external SDRAM (for data) and external Quad SPI flash.The Quad SPI flash shall hold the application binary - i.e. instructions, constants, etc. to be loaded at boot and all code to be executed.We'd like t...
Hi.I've been working on a project recently, and I've been having trouble with mounting an SD card. I've been getting FR_NOT_READY from f_mount function. Diving deeper into the code, I've found that SDMMC_GetCmdResp2 returns SDMMC_ERROR_CMD_RSP_TIMEOU...
Hi, I am using STM32G070KB controller. I tried to implement bootloader configuration via firmware as mentioned in document AN2606 and AN3155. But still its not entering boot mode. And also I need clarification for the "Execute BL_USART_Loop for USART...
Hello,I’m experiencing some difficulties trying to communicate with the embedded bootloader in SPI configuration.I have two separate Nucleo boards:- NUCLEO-H753ZI- NUCLEO-H743ZI2One of them is the master, the over is the slave (order ...
Googling around, this is unclear. The data suggests it is polled by USB code (using the ST library) for slave device presence (USB ID) but in my project I am not supporting OTG mode.The reason OTG is not supported is because a) you need to provide ad...
