Hi,The STM32H7RSxx TRM specifies, for ETH_MACMDIOAR, the following CSR values: Bits 11:8 CR[3:0]: CSR Clock RangeThe CSR Clock Range selection determines the frequency of the MDC clock according tothe CSR clock frequency (eth_hclk):0000: MDC clock ...
I have the following function to verify that a full flash sector is erased but the code never seems to exit this function and I believe it gets stuck at the point where I dereference the address value. What could be the issue?static bool check_sector...
Hello,I am trying to implement Modbus protocol in an efficient way. Untill now I have implemented everhting with UART interuot based Transmission and recption. Now I would like to implement with DMA to offload controller from much neavy lifting. For ...
I wanted to use the HDP (Hardware Debug Port) peripheral on the STM32N6 MCU (Nucleo N6 board), but CubeMX does not generate the MX_HDP_Init() function for it and does not initialize the peripheral either.Based on the reference manual, I tried configu...
The new revision of errata sheet for STM32H7 mentions a new error relative to SPI: It is particularly vague.What "fast software" and "slow SPI" frequency means exactly ? What is the minimum ration between both frequencies to avoid the issue ?What "ad...
I'm trying to use the LCD screen in STM32N6570DK, but it has an error like this`Break at address "0x18003a1a" with no debug information available, or outside of program code.`. But when I tried to view the vector table generated by disassembly, It wi...
Hi, I'm trying to implement read ADC1 value triggered with TIM6 then write it via DMA(GPDMA1 CH0). I created CubeMx project and generate code accordingly (Using LL driver). But I can't enabled DMA channel. Is there any code example about it?
I am trying to calibrate 512Hz RTC to 1ppm or <1ppm. Desired Frequency = 512HzAverage Frequency Obtained is = 512.0073HzWhat should be the value of CALP and CALM ??? (I used the CALP = 0 and CALM = 15, but still the ppm that I obtained is ~14) Could...
Hi, I want to generate a bipolar square wave with a pulse width of 100us per phase using the DAC in STM32F446RET6. But when I measured the DAC output (PA4), I found that the DAC output was not an ideal square wave, but a trapezoidal shape w...
MCU: STM32N6Register: RCC reset duration control register (RCC_RDCR)Bits 27:24 EADLY[3:0]: External access delayThe bit field is security-protected by the 1 bit. Set and reset by software.Time to wait before the BOOTROM performs any external device a...
