Generating System Clock for STM32H745ZIT chip using LDO power supply.
Hi, I've come across a few of these issues namely here but I haven't found a fix for my issue yet. I have a custom PCB based on the STM32H745ZIT6 chip which I wired up to be powered using the LDO power supply. However, I'm running into two problems a...
Unable to program a Nucleo board via an external ST-Link V2
Hello,As the questions says, I'm having difficulty programming a Nucleo-F334R8 board directly via the PA13 and PA14 SWD pins. After removing the jumpers on the built-in ST-link (CN2) I have connected the external ST link directly to the SWD, reset, g...
Resolved! STLINK V2 not detected
I have ST-LINK V2 Programmer and when I connect this with STM32MCU, it shows an error like this I have checked connections, jumper Wire.Changed the port also. But still, it is showing No STM32 Target Found. For checking Whether My Programmer is corru...
Resolved! On Nucleo H753ZI PG7 can be used as output?
On Nucleo H753ZI normally PG7 is used as USB FS overcurrent indication input and has a red LED on it.I need PG7 as output (don't ask why) going to external connector. Not using the USB FS function.So when PG7 is set low, the overcurrent LED glows.Can...
JTAG on the NUCLEO-G474RE, No device found on target.
Hello,I have an issue with the Nucleo-G474RE, I can't get the JTAG to work, I tried JTAG in 4-pin and 5-Pin-Mode, the IDE reports "No device found on target". With SWD it works in ST-Link-GDB-Server-Mode, but not JTAG. I checked JTAG is connected to ...
Hi all, im using Nucleo-144 series (STM32F767) development board in a project. I used Mbed OS for the programming.I want to make a custom pcb with the MCU, ethernet etc. and the question here is : Mbed OS will be sufficient for the programming or not?
The Nucleo we are using has build in ethernet module.
Resolved! Did I destroy my STM32F7? (SB12 removal)
Dev board: Nucleo-F767ZIDear all,as I wanted to have my own Vref+ for ADC conversions I removed solder bridge SB12 (coupling Vref+ with VDD) to input my own reference voltage (~3V) at Pin 6 CN7.After removing the SB12 however the STM 32 device is not...
Updating the firmware of a X-NUCLEO-BNRG2A1 using the integrated ST-LINK V2-1 of a NUCLEO-L476RG
I'm having trouble updating the firmware of a X-NUCLEO-BNRG2A1 using the procedure described in AN5651 page 4 ("Direct update on the X-NUCLEO-BNRG2A1 expansion board" through the NUCLEO64-L476RG integrated ST-LINK 2-1).I get this error message in FAI...
