USB VBUS or external source (3.3 V, 5 V, 7 - 12 V) Power management access point. Selection-mode switch to use the kit as a standalone ST-LINK/V2-1. One is used for STM which are male pins and the second are female pins used for Arduino. On-board ST-LINK/V2-1 debugger/programmer with SWD connector. In STM32 Nucleo there are two types of connection pins.
12KB ON NUCLEO F401RE 32 BIT
It has an ARM Cortex 32 Bit microcontroller that comes only in a single package LQFP. If shows errors also in reading internal ram, it means there is something bad with the SWD connection between onboard stlink and nucleo mcu. STM32 Nucleo F401RE is a low cost and quick to use a development board. stm32-nucleo-f401re-w5500-usr-es1 - A try to get work W5500 chip (on USR-ES1) on STM32 Nucleo F401RE. "memory display" is set by default to 0x08000000 (flash), set it to 0x20000000 (internal ram) and size whatever small (like 0x200), does it show memory (it should even if locks are enable in option bytes) or does it still report error? What error? If it shoes data, it means stlink SWD is ok, just messed up with the option bytes.
it tells "can't read memory, disable readout protecion" upon device connect to stlink utility. ST Nucleo F401RE nucleof410rb STM32F410RBT6 100MHz 128KB 32KB ST Nucleo. I have my Mini-USB cable properly plugged in to the board and directly into the computer and jumpers set to the. After compiling and flashing my programs onto my board successfully several times, the board suddenly stopped responding out-of-the-blue, instead showing just a slow-blinking red LD1 light.

In our experience, PlatformIO IDE for VSCode has the best system performance, modern interface for PIO Unified Debugger, and users have found it easier to get started.Key debugging features of PlatformIO IDE for VSCode. If you see all the above but unknown flash size, it probbly means you have enabled some locking in option bytes (flash size, if i'm not wrong, is stored somewhare is OTP flash or bootrom, don't remember exactly). NUCLEO-F401RE STMicroelectronics Development Boards & Kits - ARM Nucleo Board STM32F4 STM32F401RE 512K datasheet, inventory & pricing. does the target cpu gets recognized (top right window)? Do you see Device, dev id, rev id, and flash size (unknown flash size or 512k)? If you see device and dev id, SWD between stlink and mcu is at least working. Just to restrict the possible issue, i would suggest to open stlink utility and: View HowToUse-NUCLEO-F401RE (1).pdf from EC 401 at NIIT University.
