Hi Everyone,For my university project I work on a simple SWD debugging of an ST32 board. First I would like to establish some communication between the 2 boards (like: write the memory of board no. 2 with board no. 1 one using DAP and blink a led in ...
I have an NUCLEO-H743ZI thats works fine. So now i have buy a new NUCLEO-H743ZI2. With the samge Firmware i not able to programming the flash. I have upgrade the ST-Link V3 with the latest FW. But nothing helps. When i try to programming the Flash i ...
Hi, I am new to working with BGA components this small. Are there any particular issues (solder paste composition, paste type, avoiding caffeine, etc.) that I should consider? I want to be able to reflow some prototype boards myself before having any...
I want to make USB which is operating in Device mode to enable pullup and pulldown resistors and reset without built-in VBus sensing pin. I've tried HAL_PCD_DevConnect(&hpcd_USB_OTG_FS) but it didn't work.How can I command USB to start working ?
Hello I have a question about writing hex file in MCU (STM32F767xx) without a development board.I want to draw my PCB schematic but I am confused about which pins are used to flash the memory.I tried finding it on the datasheet but with no luck. Cou...
Hello,I just bought a STLINK-V3 because of its faster USB interface to speed up debugging with STM32CubeIDE. Unfortunately I cannot get it working. With some settings the target is not found with others there are errors during flash programming. Does...
HelloI implemented an external flashloader for STM32F767 for an external SPI Flash. The size of the flash is 256MBit. I want to readout the whole flash with *.bat file. I tried with this line:STM32_Programmer_CLI.exe -c port=SWD reset=HWrst freq=800...
Hello,I am facing a huge problem for three days, and I don't have any beginning of a solution...I made a PCB with an STM32L476 and a LoRa chip SX1272. I am using the code given by ST ICube LoraWan. After a join success, I start a custom timer and I s...
Are the VCAP_1/VCAP_2 external capacitor decoupling capacitors ? (when using the 2.2 uF with power regulator ON) PowerSupplyScheme page 77:
We use STM32 microcontrollers pretty often, and I took stm32g030f6 for some specific project. I used STLink-2 + openocd before, but I think I cannot use it on that particular one. So I take JLink but I don't have much experience JLink. I spent whole ...
