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) ...
