Resolved! Maximum external clock frequency for STM32H5 timers
What is the maximum clock source frequency can I use as an external clock for timer?I have a 20MHz source and PLL frequency made out of this source. The purpose - generate lower frequency pulses that synchronous to that 20MHz clock with controlled de...
Resolved! STM32G474RET6: Always boot from bank1 and to jump bank2
HelloIn STM32G474RET6 I want to have 2 banks. Bank 1 for golden (boot image) and Bank 2 for an application image.As I want to have a robust solution I always want to boot from Bank 1 (address: 0x8000000), to check if valid firmware exist in Bank 2 (a...
STM32F051K6 Does have a drift of 7 milli seconds per 1 hour running on HSE
Hi ,We are seeing STM32F051K6 have a drift of 7 milli seconds per 1 hour running on HSE . Time drift of 7milli seconds for 1 hours is 1.944 Parts Per Million ( 7000 micro seconds / 3,600,000,000 Micro seconds = 0.000,001,944 )The OSCILLATOR has ± 10 ...
Resolved! DMA with SAI
Hello,I would like to use DMA with SAI but I am having difficulty writing the code. Can you check if my code is correct and why I cannot retrieve the RX values ? /* USER CODE BEGIN 2 */ HAL_SAI_RegisterCallback(&hsai_BlockA1, HAL_SAI_RX_HALFCOMP...
USB / UART bootloader special / extended special commands
Ok, 2 part question. The UART bootloader defined the "special" and "extended special" commands. Those are nicely integrated into OpenBL. So if I wanted to write my own custom "OpCode", what range would I use ? Looks like some are used for STM32WB (FU...
Missing or unaligned sample in buffer when using ADC and DMA
I am using a STM32F767BITx LQFP208. I have to measure 12 channels. 6 channels measure the voltage and 6 other channels measure the intensity. Samples from voltage and insitensities shall be done as simultaneously as possible.I am using ADC1(voltage) ...

NAND FLASH 25N01GV with STM32H725 sector erase failure
Hello everyone, I am trying to use STM32H725 processor with NAND FLASH 25N01GV. The installation seems successful. But sector erase always fails with the same error Status Register(0xC0) = 0x04 (EFAIL - Erase Failure )1. JEDEC ID read successful.W25X...
Systick is not triggered and Interrupt handling problem in STM32WB55 series
Hello, I am trying to built an applicaiton on STM32WB55 MCUs that contains interrupts and many digital signals. My code working very fine on development board and I am trying to implement this code on custom STM32WB55 PCB. The Problem is vect...
