-M Debug Probes With Target Power Supply
Capability
Some third-party ARM Cortex-M debuggers (for example, Segger J-Link and IAR i-Jet) can optionally
supply a 5-V voltage to the target system through pin 19 of the debug connector. The LDO IC2 uses this
voltage to generate the 3.3-V target supply voltage. To use the LDO, make sure the following jumpers are
set as shown here before connecting the debug probe (see
Figure 1-3
):
•
JP8: Closed
•
JP12: Closed
•
J1: Close 1-2
•
JP1: Closed
•
JP2: Closed
•
JP16: Closed
If the debug probe supplies a logic level voltage through pin 19, the LDO can be entirely bypassed using
JP15. Always follow the voltage limits defined in the device data sheet.
