About failure when writing nucleo-F446RE using Openocd.

Hi,

Writing nucleo-F446RE using Openocd repeats success and failure.

The following is the log at that time.

How can I get rid of this error?

— third time —

Same as the first time

Repeat below.

#—openpcd.cfg—

telnet_port 4444
gdb_port 3333

source [find board/st_nucleo_f4.cfg]

init

proc flash_elf {elf_file} {
    reset
    halt
    flash write_image erase $elf_file
    verify_image $elf_file
    echo "flash write_image ($elf_file) complete"
    reset
	  exit
    halt
}

By the way, if I modify “adapter speed 2000” in “stm32f4x.cfg” to “adapter speed 1800”, the message “Info: Unable to match requested speed 2000 kHz, using 1800 kHz” disappears, but the problem still occurs. …

Thanks.

I haven’t seen this before; try cross-posting here as well https://forum.arduino.cc/c/hardware/portenta/91 and maybe someone knows what’s going on
