i have MCU circuit with stm32g474met3 as the processor, designed such that it controls the main board charging circuit and it keeps burning randomly at random times could be 5 hours or 20 minuts or even few days I cant figure out why, it burns whethe...
Hello,The STM32L476 MCU is not booting, and it seems to be stuck at address 0x08000228, as shown in the attached image. It used to boot and work correctly before.At some point, it stopped booting and no longer functions as expected. What could be the...
Posted on October 02, 2012 at 10:50Hi! I am trying to use the CS43L22 in a very simple way: only to amplify an analog signal created with the internal DACs of the STM32F4. On the Discovery board the output of DAC1 is routed to AINxx. So I create a 0...
We have a device with corrupted SRAM2 content that is failing in the field. Is clearing the SRAM2 when booting the unit using its ROM bootloader possible? I tried to read SRAM2 content by the serial port when it boots by the ROM bootloader, but it fa...
HelloI am testing new MCU's. I have a ST-Link V2 and using a STM32F401CCU6.At the start I had a simple LED flasher application however after I could not run it I started stripping everything out.This is when I saw that I can actually not even run an ...
Hi, I would like to identify the source of the interrupt that caused the MCU to wake up from Standby mode. To do this, I check the RTC_FLAG_WUTF and RTC_FLAG_ALRAF/RTC_FLAG_ALRBF flags after the system wakes up to determine the wake-up source. Howeve...
Dear ST Community member,I hope you all are doing well.We are using STM32G473VET6 and IMP34DT05TR for Audio acquisition. The PDM Microphone needs a 2 MHz clock signal to operate properly. However, we are getting an error after configuring PLLQ at 2 M...
Hello,I am using an STM32F746VGT6 with a LAN8742A PHY to implement a basic TCP server using freeRTOS + LwIP for text communications. I've attached the code below: #include "bti_tcpecho.h" #define TCP_SERVER_TASK_PRIORITY 10 BaseType_t bti_tcp_serv...
Hi I am using STM32F407 evb in which I have configured both CAN1 and CAN2 ,I am sendind CAN1(3 ids 501,502,503) and vice versa from CAN2 same I am sending but I am ble to recive all three id on CAN2 Rx but only one ID iam receving on CAN1(501) .I am ...
I am working with STM32F401RE and IHM04A1 driver board. There is timer1 channel 3 in EN-A (PA10) for IN1A and IN2A. However, there is no timer channel in EN-B which should be used for IN1B and IN2B. What should I do for the timer in EN-B, that is, PC...
