Hello everyone,I am experiencing a fairly impactful problem with STOP3 mode in a FreeRTOS application that runs in a STM32U585VIT6Q.The system has this behavior: it wakes up, performs operations on SPI3, write some informations on internal FLASH, ret...
I am just switching clock source to MCU in RCC_CR register by making HSEON bit of above register high and waiting till HSERDY but turnsup. But thing after HSERDY turns up when I read rcc_cr register both HSEON,HSION bit of RCC cr are at logic 1. Then...
I'm trying to use the RAMECC monitoring subsystem on an STM32H743 but there's some behaviour I don't understand. I've read the reference manual (RM0433 rev 7) and application note AN5432, as well as some related forum posts here.If I set an interrupt...
Hello, I'm trying communication between stm32G0 as I2C slave and a rapsberry pi 5 as master.on pi side, the call is: self.cpt = (self.cpt + 1) % 255 b = self.bus.read_i2c_block_data(42, self.cpt, 5); I've seen in several places on the web tha...
OverviewAt my job, I was recently tasked with handling ECC errors in both RAM and flash memory. Additionally, I needed to test the error handling by injecting ECC errors. Figuring out how to do this was a nightmare. I looked over AN5342 countless tim...

I generally don't open threads, but one recurring frustration I've had with Keil on CM0(+) platforms is with printf() going off the rails with "%.2lf" "%.3lf" type formats.I've seen more often than I care for, a situation where code working elsewher...
Hello everyone. I am trying to write a bootloader with STM32H750IBT6 and mt25ql512. I am trying to adapt the ExtMem_Boot example of STM32H750-DK to STM32H750IBT6 by modifying it, but I can't succeed. It doesn't make sense why STM32H750IBT6 does not w...
