I am using STM32H733ZGT6 in my project. For Ethernet communication, KSZ8081RNB PHY is configured in 25MHz mode such that PHY has to supply the 50MHz clock to MAC in my MCU. Problem here is, when I try to reset the MAC and its DMA controller by settin...

Hi, I am trying to receive 19 bytes in UART in DMA mode. I have configured both the peripheral (DMA_CCR_PSIZE) and memory alignment(DMA_CCR_MSIZE) as byte. When I Enable the UART receive in DMA mode, I encountered with Hardfault exception. After debu...

I stuck with ADC implementation understanding. Please help me to get this.In STM32L5xx reference manual (RM0438), ADC main features are given as follows (Page no. 685 in RM0438 Rev7)" Up to 2 ADCs which can operate in dual mode:ADC1 is connected to 1...

I am working on STM32L552 Nucle0-144 board with Trustzone enabled. Secure code starts from 0x0C000000 and non secure code vector table located at 0x08040000. After completing the initializations in secure code I am calling non secure reset handler by...

Hello,I need a help in Motor frequency calculation with more precision. I am using STM32F070CB for my application. My requirements are1) Monitor the Motor frequency based on quadrature pulses.2) If Frequency varies by +/-15%, need to process some saf...

Hi, Piranha, thanks for your reply. Yes, Ethernet peripheral clock and RMII pin configurations are also done. Root cause I found that, in new HW design, PHY Reset Signal pin is connected to separate MCU GPIO whereas in the earlier HW design PHY reset...

Hey, From the stacked frame, I found the root cause. Due to un intended increment of one buffer index, USART Instance is pointing to 0x5550xxxx which is not a valid address. Corrected this and now my code is working as expected.Thank you all.

hello TDK,Thanks for your reply. I am working on Cortex-M33. Controller is STM32L562xx. Trusrtzone is not enabled. I am new to this device. IDE I use is IAR EWARM 9.10.2.I agree that DMA is not the cause of this problem here. I have tried to trace th...

Hi @JHOUD , thanks for your reply.Now I learnt that the area I am considering (0x08040000 - 0x0807ffff) as a non secure is actually configured as secure in secure area2 Watermark Registers(SECWM2_PSTRT, SECWM2_PEND). Now I have modified this area to...

Hey Waclawek and Clive,Your recommendations helped me to find the answer for my Clarification 1. The Slave timer I can configure in Input capture(IC) mode. By this, I can configure IC Prescaler with my choice of number of pulses(may require in case o...

Ethernet MAC and its DMA controller is not getting reset in STM32H733xx MCU

Can I configure the UART in DMA mode for transmitting and/or receiving ODD number of bytes?

What is the meaning of multiplexed channels of ADC's in STM32L552xx or STM32L562xx family micro controllers

In STM32L552 Nucleo-144, unable to load non secure code when call happened from secure to non secure.
