I’m trying to get my STM32H743 to communicate with a Cypress S25FL128S.I want to change the state of the Configuration register bit 1 from the default of zero to a one.I want to use the HAL_QSPI API to perform this write but I’m confused on how to ad...
Hi ST , I have 100 qty of STM32L4R5VG with bootloader version 9.2 which is fault bootloader . AN2606 says that the bootloader version 9.2 has a trouble with system reset repeatably so can not be used for bootloader. I tried to fix this issue by myse...
Hello everyone,at the start I would like to apologize for my English. It's not the best so I hope that you won't have any dificulties with reading and understanding my problem.I have very strange problem with programming STM32F070RBT.So I am trying t...
Hi all,i initialized the TIM5 CH4 PWM with the cube mx interface and then i used :HAL_TIM_PWM_Start(&htim5, TIM_CHANNEL_4);The output is supposed to be observed on PI0 - D5 on the CN4 on the back. There is nothing on the oscilloscope though. Do you k...
I used the project in B-G474E-DPOW1, named "USB-PD_Consumer_1port" as usb pd sink, everthing is ok. However, I create the project with the params from "USB-PD_Consumer_1port" just without the usart trace, the new project can't run normal, got error i...
While writing the simplest example I could come up for using the HAL I2C routines, I came across what seems like a clear-cut bug. This is for the latest version of STM32CubeF4 (1.24.0), identified in stm32f4xx_hal.c as "STM32F4xx HAL Driver version n...
Posted on February 02, 2015 at 13:03I'm trying to create a USB CDC+MSC composite device using STM32F4 so that it gets automatically recognized by both STM32 CDC driver and as a standard MSC device. Does ST provide a VID/PID pair for such a device? I...
From the document, the sink will check:A SINK must present an Rd resistor and detection is done in two steps:1. detect the presence of Rp resistor2. detect a VBUS ON.I tested in stm32g431rb, connect ucpd_cc to a power adapter(source), Source send the...
I have a custom board with STM32L4R MCU (STM32L4R9ZGJ6). While the application software and its USB interface is running I can't enter the USB bootloader. I checked AN2606 but found no issue. STM32L4R takes its internal clock for USB so it seems easy...
I found my STM32L4R5VG 's bootloader version 9.2. The AN2606 says that the bootloader version 9.2 has a trouble with system reset repeatably so can not be used for bootloader. The version 9.4 resolved this issue. How can I update my STM32L4R5VG 's bo...
