Hi experts,

We have created a project on WICED 43xx_Wi-Fi sdk for STM32F412 MCU+43438 wlan chip.

We have connected st-link V2 debugger to the EVB and we could see "STM32 STLink"​ in windows Device Manager.

When we used openOCD to flash debugger to EVB, it would show below error:

Here comes the command and terminal output that we used to programming.

Please help for clarifying this issue and if need anything information please let me know.

Your help will be appreciated.

Apparently you created 'stm32f412discovery.cfg' yourself? This file should in turn *include* 'stm32f4x.cfg' automatically, no need to specify this on the command line.

The stm32f4x.cfg bundled with openocd sources works fine and uses 'swj_newdap' instead of 'newdap'. So probably you're using (parts of) an older version of openocd mixed with a newer one?

Look at e.g. http://openocd.zylin.com/#/c/4321/7/tcl/board/stm32f412g-disco.cfg, remove the QSPI stuff and use that as a template. But please don't use 'stm32f412discovery.cfg' or similar as file name, as that should be reserved for a plain STM32F412G-Discovery board only. The best way would be to create cfg file specific for your board which just *includes* stm32f412g-disco.cfg and adds the additional stuff for your board extensions.
