This topic is inspired by discussions in ST forum and ARM forum, where a proper cache maintenance was sorted out and an example of a real-life speculative read was detected. Also there is another discussion, where a real-life example of cache evictio...
Dear Sir, Good morning!I use STM32F407vgt6. I need chip ethernet controller with MII interface from STM. I previously used DP83848 from Texas Instr. Please recommend me ethernet controller from STMTIASincerely,Vladimir Naumenkov
When i debug SPI1 on STM32F407, program will jump to 0x00 when write DR register, MCU reset and loop continuely. when i measure the SCLK signal using oscillator, SCLK is always high after SPI1 is enabled When i write to DR of SPI1, the code jump to ...
Hi,I am using SPI on STM32H74II MCUFirst I am using a software NSS and not a Hardware NSS because it doesn't work.I need to transmit 1 byte and receive 1 byte, the two commands one after another see the simple code below : RFID_SS_ENABLE; statu...
Dear All,My customer using STM32F205ZG and I have the following issue.I am accessing dual port memory using FSMC function, but when I measured the waveform, I found that CE(CS) did not increase due to BUSY(WAIT). See picture below.setting value : "Ad...

I am using STM32L496ZGT6P. When using DAC along with DMA to generate voltage and frequency of my desired range. But I am unable to get hold of the frequency setting. Sysclk I set is 4Mhz. 20 is prescaler value, 4Mhz/20 = 200000.This is further divide...
I found a issue.if the code isHAL_PWR_DisableSleepOnExit();HAL_TIM_Base_Start_IT(&htim2); it will stop at "if (IS_TIM_SLAVE_INSTANCE(htim->Instance))", but i didnt set break point at here.if i change code：HAL_TIM_Base_Start_IT(&htim2);HAL_PWR_Disable...
Hello,I am trying to make STM32F020c8t6 enter boot loader by connecting the Boot0 pin to HIGH via a 10k as given in some forms and pressing the reset. I connected the MCU UART1 to Laptop running Cube Programmer and use the UART option. The MCU uart1 ...
The U2 on my STM32F407G-DISC1 is shorted and needs to be replaced.Is the STM32F103CBT6(U2) pre-programmed, or can I just replace it with a new blank STM32F103CBT6 and it gets programmed when you DFU firmware the STM32F407G-DISC1 board.Hardware isn't ...
