Hello,Target is power from another source. STlink from USB of laptopI was wondering if the power ON/OFF of STLINK and the target sequencing will damage either the devices? I had one STLINK v2 seems to be damaged while debugging and later it is not ab...
Hi team, I am doing experiment with NUCLEO-F439ZI board. after some time the LD4 "LED" was not glow. after I unplug the USB cable and reconnect the windows shows the flowing error"Power surge on the USB port – Unknown USB Device needs more power tha...
Hello Community,I want to use an external Debugger (Segger) with this Board. For this the jumper JP3 is left open to hold the STM32F7 (ST-LINK) in RESET.I attach the Segger to CN8. When connecting I get following message: Connecting to target via SW...

Hi,I got a strange behavior during debugging my bare metal application on STM32F745ZGTx. The emulator is ST-Link V2, with "B 2018 02" printed on the back. The Hard Fault exception (unaligned memory access) is triggered randomly. I mean, the PC causin...
Hello.Looking for a reference circuit diagram of STM32F723VET6.If not, I'm looking for a circuit diagram of 32F723 EDISCOVERY.Please give me a link.The reason is that I want to use vdd as 1.8V instead of 3.3V, but I want to refer to it. think you.
Hello,I tried to EEPROM write/read test but it seems to not have written into EEPROM normally.My defined functions corresponding to EEPROM are like following.#define FLASH_USER_START_ADDR ((uint32_t)0x8008000)#define FLASH_USER_END_ADDR ((uint32_t)0...
I have a windows 11 laptop with both ST-LINK Utility and STM32CubeProgrammer installed. I can connect to my STM32-based motherboard using a ST-LINK clone and ST-LINK but not with STM32CubeProgrammer. Anyone know what I'm doing wrong?
