3. Troubleshooting
The following section reports some tips to be followed if the WB2072E00A platform is not
recognized as a CMSIS-DAP device once connected to a PC USB port, or if user is not able to
connect/debug to the selected platform through a CMIS-DAP programmer/debug tool:
1. The WB2072E00A platform starts always in "MAINTENANCE" mode.
a. The USB_CMSISDAP firmware is not loaded. Follows the instructions in the
WB2072E00A user guide, section 2.9.4"USB_CMSISDAP firmware update" in order to
load the USB_CMSISDAP firmware. Please notice that this condition is not expected,
since the USB_CMSISDAP firmware is programmed at WB2072E00A manufacturing
time.
b. The application loaded in the WB2072-00 module makes the device continuously reset.
Since the RTSN signal is used at the startup by the USB_CMSISDAP firmware for
choosing to start in "MAINTENANCE" mode or not, it is necessary to disconnect the
RSTN signal of the WB2072-00 module from the USB_CMSISDAP. In order to do it, user
must perform the following steps:
1.) Remove the jumper JP4.
