Hi,reading AN2606 "STM32 system memory boot mode". Then I'm using the STM32G031 I should use the Pattern 11 options to enter the boot after an reset. This Pattern 11 reference to two bits (BOOT_EP and USE_BOOT0_OPT) . I cant find any information abut...
Hello, ST expertsSTM32H743 is used on our custom design. Everything is OK when working on 64MHz and 48MHz, even at 32MHz CPU frequency. But f_write keeps on failing when working on 16MHz and lower CPU speed, the error number is FR_DISK_ERR. SDIO card...
My USB user application works fine, but DFU mode using USB works weirdly, sometime it work, but regular it is not recognized by host PC.
Hello,I'm writing a basic program that prints something over and over through VCOM port on USB-OTG, on a STWINKT1 board.This board uses a STM32L4R9ZIJ6 MCU, so I followed this guide: https://www.youtube.com/watch?v=rLnQ3W8gmjY (and many others).The p...
Hi, last time I ported an Azure RTOS project there were only a handful of BSPs so I had to do some manual fiddling around to get it running on a nucleo board. Now that there is full support for H7 processors in the 2.0 package I'm wondering what the ...
I have some problems about programming USB CDC. The program goes into ERROR_HANDLER in MX_USB_DEVICE_Init();. I think I made a mistake during set the configuration for running USB_OTG_HS and USB_DEVICE in ioc. (gui of STM32CubeIde). In " STM32F4xx_...
App note AN2606 on bootloader operation, figure 57, shows the flow chart for the STM32H74/75 series. One block is labeled "USB cable Detected". Exactly what is the criteria for this? Is it based on DP/DM states? Is it based on VBUS measurement? ...
