I am using standard USB libraries available on ST website. Is there a function available in these libraries where I can check a status flag and confirm whether a data transfer via USB virtual Com port is complete or not?
I need to transfer 2 M Bytes of data via USB virtual com port of STM32F429 microcontroller, withing 2-4 seconds.I am using the USB standard libraries available on ST website. I have successfully transfered small strings, But when it comes to the larg...
Hi,I am using an STM32G071CBU6, and using the USB-PD stack as a sink only. I can successfully negotiate PD contracts from a source etc, this all work fine.However, I have an issue when powering up using the Dead Battery lines. They seem to work OK in...
Hi Guys,I'm trying to do basic communication via Ethernet on a Nucleo H723 board. I would just like to send and receive a few Layer 2 frames. I'm going through the reference manual and the ETH HAL files to learn how the ethernet peripheral works. Wha...
It seems unprotected flash can be programmed and then protected using user application launched native STM32 USART BOOTLOADER, but protected flash can only be cleared, but not reprogrammed without also having access to the boot pin configuration. (A...
It is working firmware STM32H7-DISCO with freeRTOS using internal flash. Almost full my binary. I planned to develop my firmware internal flash to SRAM. I modified .ld file and able to boot SRAM. Please check the below changes./* Memories definition ...
