I'm using the STM32H750. Using the discovery kit I developed a system that always boots into the system bootloader. When I start the application code using a dfu-util, the application code starts a USB FS CDC device and I can communicate with it as v...
what i noticed is if i create n no of files, only 8 files are displayed however the remaining files are also created but not displayed, i am using elm chans fatfs. What could be the problem why only first 8 files displayed on pc .Kindly let me know ...
There are a couple of inconsistencies in AN4826.First one that has been repeated in other posts is that there is a bug in the bootloader and BOOT0 pin's state is actually irrelevant as it always boots from BOOT_ADD0 anyway.So the select BOOT_ADDx bas...
I'm trying to get my board set up to receive data via UDP, run an FFT and then return the data back to the requesting port, I receive and echo back data but as soon as I try to process it with the FFT function the system locks up waiting for a memory...
Hi,I am using a CAN bootloader to update my application. But after flashing the application and jumping from the bootloader to the reset vector of the app, the program stalls after calling NVIC_EnableIRQ(CAN_TX_IRQn). Is there a problem that the boot...
Hello,I am using ST USB Device library, STM32f746 controller.I am not facing any issue while sending data to the Controller from the PC host application.But while reading from the device , the device is disconnecting.Can Any one help!Thanks,Upender.
in stm32cubeMX configuration of SPI in slave mode, it asks for user parameter input for clk prescaler, which then derives the clk rate. My understanding for SPI operated in SLAVE mode is that the master end, instead of the slave end, generates the c...
Hi,I followed the AN3990 and managed to update the code supplied to use HAL and get it working correctly on our custom board. But in my readings on custom bootloaders in the forums, it mentions things like disabling interrupts before jumping to ...
I have configured 5 interrupts on EXTI line.....It works fine when I operate one at a time but misses out one interrupt when operated simultaneously.....Following is my GPIO configuration:- void MX_GPIO_Init(void){ GPIO_InitTypeDef GPIO_InitStruct; /...
if stm32cudeide can view the bootloader and update the bootloader of MCU that is already writed by the vendor, like external oscillator or some other options ?i have already installing the STM32CubeIDE, STM32CubeMX and STM32CubeProgrammer. is there ...
