I am exploring X4M03 firmware programming capability. I am following "XeThru Module Firmware Programming" steps. I connected SEGGER J-Link Mini and started "Atmel Studio 7". Under the "Device Programming" window I selected tool and proper device. The problem I am having is that connection test fails. Do I have to first erase MCU in order to test the connection as described in section 2.1? Connection fail image error message: https://ibb.co/bdbrVfQ Also, I am not understanding why the instructions want me to first program "xep_x4m0x_s70_with_bldr.hex" and then using python tools to upload new firmware. Can't I simply select my new firmware from "Memories" in "Device Programming" window and program it? One more question, we got X4M03 rev 5, is the factory firmware available to download? In case I would like to restore factory firmware. I assume it might be "xtXEP_binary-3.4.7\bin\xep_x4m0x_s70.hex" or "xtXEP_binary-3.4.7\bin\xep_x4m0x_s70_with_bldr.hex" or xtXEP_binary-3.4.7\bin\xep_x4m0x_s70_4bl.hex"
