Swd Debugging; Swd Jumper/Shunt And Push Button - Active-semi HYDRA-X10 User Manual

SWD Debugging

The HYDRA-X10 module comes equipped with a fully operational and ready to be used CoLinkEx compatible
SWD debugger. User can utilize this link to download code to the PAC5210 device through the CooCox IDE
or CoFlash FLASH loader application. Both of these applications, along with the CoLinkEx USB driver, can be
downloaded from the www.coocox.org
In the event the user desired to utilize a different debugger, connector J1 offers access to the PAC5210 SWD
lines. The CoLinkEx debugger must be separated. Separation can be obtained by flipping the S2 DIP
switches 3 and 4 to the OFF position.
The integrated SWD module is powered from the PAC5210's 3.3V regulator.

SWD Jumper/Shunt and Push Button

Jumper Description
JP1 Used to program U3 microcontroller with CoLinkEx SWD firmware. In Factory use only.
S1 SWD MCU Reset Push Button
The S1 push button resets the SWD MCU. In the event SWD communications are not operational while all
voltages are present, pushing the button may restore SWD functionality.
NOTE: It is highly recommended the JP1 to never be populated with a shunt. Doing so will configure the SWD
MCU to behave like an USB storage device. This mode is only meant to be employed when programming the
SWD MCU with the CoLinkEx firmware.
