Hi, I have written a custom bootlader which verifies CRC of the aplication and then jumps to the application. I wanted to know how can I check the total execution time it takes from start of the bootloader execution to the start of the application ex...
Hello and thanks in advance for reading my post. I am currently working on my dissertation, trying to implement a digital signing algorithm on a Arm Cortex-M0+ microprocessor. I'm using a NUCLEO-G0B1RE board with a stm32 with the same series. This bo...
Hi,We would like to use the standard USB DFU supplied with a STM32H747IGT6 with our own Vendor ID (VID) and Product ID (PID) instead of the default STM VID and PID. We are entering USB DFU mode by pulling the boot mode pin hi. We can run the DFU thro...
Hi, My application has a bootloader, recently, I allocated a large block of memory on top of SRAM to protect the data from system resets, this causes the highest address of user stack changes, when this highest addresses of user stack are different i...
Hi everyone,I’m working on a custom bootloader for an STM32H750 and need some help. My goal is to be able to update the unit from USB and for doing so I use an external eeprom to store the MCU FW and load it into RAM at startup. The main reason to us...
Hello I just purchased a STM32 board. Here is the link:https://www.aliexpress.us/item/3256807324905710.html?spm=a2g0o.order_list.order_list_main.5.3b001802nQFgBb&gatewayAdapt=glo2usaI ordered the Dual Channel version.Here is an image:How do I program...
i have written a driver code to run 4 wire resistive touch panel. I use only 1 adc and change its adc channel during runtime. Like i set X+ and Y+ as output high by default and X- and Y- set as low by default and set X- and y- pull down to make ADC r...
We have made a batch of 30 boards using the STM32U073. One of this 30 boards is not working as expected.I am able to connect STM32CubeProgrammer to the processor using the SWD port. I am using STM32CubeProgrammer v2.18.0. If I try and erase the flash...
Hello I want to understand Sequencer concept as per below link. https://wiki.st.com/stm32mcu/wiki/Utility:SequencerI tried to search stm32_seq.c in STM32F4 package but couldn't find. I don't see any sequencer folder under utilities folder.
Hi! I am working on a project where we are using DMA driven SPI-transmissions. I am using LPTIM1 to synchronize readouts of multiple SPI busses. The setup works when the transmissions is equal or below 128 bits (for SPI1-SPI3). When HAL_DMA_MuxSync...
