Hello,We already have developed a USART boot-uploader for a project of ours, testing it on an STM32F7XX customized board. I can bring up the bootloader by init command ( 0x7F ) and get a response 0x79 ( ACK ). But an extended erase command fails to r...
Hi everybody, this maybe a very simple question but it is complex to me.Are they only needed between DMA and Memory?If we have few buffers but they are same RAM, do we need to clean/invalidate before copy or read?If a buffer is located in uncache (by...
Hello I just got a STM32H747I-DISCO board. I have no idea how to program it. I am using STM32Cube ide. When I use only CM4 main to led blink debugger gives error. When I write led blinking code to both CM4 main and CM7 main then this time debugger is...
... just reporting, no question...Today I had a quite bizarre problem with my ADC when testing the same PCB with RevY and RevV chip.I operate the ADC in regular single mode (I tried also regular discontinuous mode), very slow sampling (865 cycles)), ...
Hi,I want to calibrate RTC(which is powered through LSE-32.768KHz) in stm32F051 and want to know how CALM value is calculated in RTC calibration register(RTC->CALR).Thank you.
