Hi,We are using STM32F091VCT6 in our application, however we are observing some instance of RTC losing time. We checked entire datasheet but were unable to figure out how much time the RTC takes to switch to VBAT after VDD falls below given threshold...
Hello.I'm having issues with STM32CubeMX and VScode setup. I have the STM32 VScode extension installed and all the extras that were required as per this page ( https://marketplace.visualstudio.com/items?itemName=bmd.stm32-for-vscode ). I generate a m...
Hello,I am using STM32H7 as SPI slave with DMA transfer, the communication works fine till 18MHz of clock frequency from the master side however for higher clock speeds of 20 MHz - 31MHz it is noted that the bit shifts by 1 bit for the whole stream o...
Hi all,I am working on a QSPI driver for W25Q512 flash memory (extloader for stm32cubeprogrammer and main firmware driver). I had a look at the errata ES0392 - Rev 13 and I have a question about paragraph 2.8.4: 2.8.4 - QUADSPI internal timing critic...
Hello,I am working with the STM32G0B1CCT6 MCU and facing an issue while flashing firmware using ST-LINK.During the flashing process, I get the following error:Error: Sector erase operation has failed at least for one of the existing specified sector...
Are STM32F0 microcontrollers railway approved to use them when I'm designing rolling stock electronic component? or there is any certification regarding compliance with railway/rolling stock?
Hello,I came across this document here https://www.st.com/resource/en/application_note/dm00622045-stm32h7-series-lifetime-estimates-stmicroelectronics.pdfWe have a H75x custom board running the MCU in VOS1 at 400MHz with external 1.2V core power supp...
Greetings, I'm having an issue with low-power modes. I'm using a STM32U585 MCU and while in run mode it is consuming around 100mA, which is a lot. I tried to enter in Sleep, Stop and Standby modes right after the main declaration:int main(void) { ...
Hi , I am also making custom board for GPS, and same issue I am facing, unable to connect via SWD, Please help to debug.
Dear St,I hope this message finds you well.At our company, we are currently in the process of obtaining product certifications. To comply with these requirements, the certification body has requested RoHS documentation for the components we use, incl...
