Products & Technology Wio Series

Regarding the MASS ERASE, I was trying on my own to erase either part or all of the memory to try any interaction with it.

  1. Have you tried writing without MASS ERASE?
  2. Are you trying to write a hex file for the first time? Or were you able to write them before without any problems?
  3. Is the connection between ST-Link and the target board correct?
ST-Link       Target Board
SWCLK   <---->   CLK
SWDIO   <---->   DIO
GND     <---->   GND

Please refer to the following connection.
