STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
OverviewAt my job, I was recently tasked with handling ECC errors in both RAM and flash memory. Additionally, I needed to test the error handling by injecting ECC errors. Figuring out how to do this was a nightmare. I looked over AN5342 countless tim...
Hi,I am currently working on a Battery Management System (BMS) and an instrument cluster. I need your assistance with some issues I’m encountering while communicating between the BMS and a custom cluster board using CAN.We have two custom cluster boa...
I am trying to make a custom external loader for a qspi nor flash. the erase sector and write operation is success but after I tried the read operation the operation is fail the device is disconnected and showing this message I have tried to run a pr...
I generally don't open threads, but one recurring frustration I've had with Keil on CM0(+) platforms is with printf() going off the rails with "%.2lf" "%.3lf" type formats.I've seen more often than I care for, a situation where code working elsewher...
Hello everyone. I am trying to write a bootloader with STM32H750IBT6 and mt25ql512. I am trying to adapt the ExtMem_Boot example of STM32H750-DK to STM32H750IBT6 by modifying it, but I can't succeed. It doesn't make sense why STM32H750IBT6 does not w...
Hi,I am working on a project that store the Configuration data of one device, It needs to be stored in specific sectionstatic unsigned char myBuffer[4] __attribute__((section (".m_data_20000000"))) { 11, 22, 33, 44};with this command I'm able to stor...
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...
Have a problem with write Scatter-Loading Description File for STM32H743 (arm keil).I need to map SDRAM memory.Regular I do it like:RW_RAM1 0xD0000000 0x00800000 { ; fmc bank 2 *(SDRAM) }On all other MCU's it's work perfect, but not for stm32H7. It'...
Hello, I am looking for a way to set up DMA to transfer from peripheral to circular buffer triggered from Timer I hoped I could set it up just like it is described here, just change the source:It samples data as expected but only once, it does not re...
Dear All,I've been using MCU/DSP-related products for over 10+ years, but I've always had some confusion about clock multipliers and dividers. I'd like to ask for everyone's opinion on this topic.As shown as below figure (it's the clock configuration...
