Resolved! Detecting JTAG Access on the Board
Hi, I am using the B-U585I-IOT20A Board and I want the board to notify me in some way if someone is attempting to access and modify its content via JTAG. Is there a way to do this?

STM32F765VGT6 with 216MHz CPU clock frequency
I designed a circuit board with the STM32f765vgt6 chip following ST's hardware recommendations (two 2.2uF ceramic capacitors with low ESR connected to Vcap1, Vcap2).I'm having the following issues: When I initialize the CPU clock frequency to 216MHz,...
Resolved! STM32L475 and URC's management via UART
Hello,I'm managing a Wifi modem using one of the USARTs of the STM32L475.Modem is working fine when sending and receiving AT commands and data, but I'm not able to receive URC's.I only receive URC's when they come 'together' (very close) to the answe...
Writing to flash on power loss using PVD on STM32F103C8T6
Hello.I am trying to save variables to flash when there is power loss that i detect using PVD. I got PVD to work correctly and trigger interrupt at 2.9V, but now i cannot find the right examples to see how to save the variables quickly to flash. I h...
STM32H747XI EXTI interrupts of M4
Hi,I am migrating my project from STM32F778AI to STM32H747XI and I have some issues regrading EXTI interrupt on M4 core.I use custom board with J-link programmer.I have simple button with hardware pull-up and I configured pin to be EXTI11 on M4 (enab...
Resolved! STM32U5 SPI DMA in DMA_LINKEDLIST_CIRCULAR mode occurs HardFault error
HiI use STM32U5 SPI2 in Salve mode to only receive data，and the data-size is 16Bit. Because the rate is very fast, I use the DMA_LINKEDLIST_CIRCULAR mode combined with the DMA half-full interrupt solution.When I used HAL_SPI_Receive_DMA() to start SP...
ADC Multichannel Polling Example
I'm writing firmware for stm32c011f4u6 using Keil5. I downloaded and checked an example about ADC from the homepage, but I only found the code that uses DMA. Is there any example of using ADC with Polling instead of DMA? Also, I need an example for m...
reading Flash EData on STM32H573
started using STM32H573 recently, having issues with Flash Edata when reading data from EData area, which crashed at HardFault_Handler() with STM32H573I-DK. But it is running fine with NUCLEO-H563ZI for the same job.The example project “FLASH_EDATA_E...
How to interface STM32F411 to CODEC SSM2604
Hello, I'm new to the forum and I want to ask about how to make the I2S connection between an STM32F441RETx and an SSM2604 Audio CODEC.Here are the corrections:My doubt is on how I should connect the Serial Data pins from the CODEC to the MCU. Should...
Is Circle OS around anymore?
Posted on June 24, 2016 at 07:52Circle OS used to be a GUI software for the STM32 line of microcontrollers. I am looking at building my own object handling software from the ground up, but I need some guidance so I wanted to reference Circle OS.Does...
