If error code 0xF015 or 0xF00x (e.g., 0xF002) occurs at the start of measurement, it indicates that communication between EVRICA and the user system is not being established correctly. Possible causes and solutions for these errors are listed below.
1. Physical Connection Errors (JTAG/SWD signal disconnection, broken wires, etc.)
Refer to the "User System Interface" chapter in the KS100_users_manual.pdf and verify that the connection meets the specifications.
Check if the issue is resolved by changing the "Connection Interface Setting" from SWD to JTAG, or JTAG to SWD.
2. Incorrect MPU-Specific Settings
Configure the MPU-specific settings according to the microcontroller you are using.
3. JTAG/SWD Clock Speed is Too High
Click the "Details(D)>>" button on the MPU-specific settings screen.
Change the "Clock" in the "Connection Interface Settings" to 1MHz and verify if measurement can be performed.
4. Signal Conflict (JTAG/SWD signals are shared with a debugger, etc.)
If JTAG/SWD signals are being used simultaneously by another device (e.g., a debugger), it causes a conflict with EVRICA. Please connect only EVRICA.
5. JTAG/SWD Pins are Disabled
This occurs if the pins are multiplexed with GPIO and GPIO is active, or if the pins are disabled due to security settings.
Please enable the JTAG/SWD pins or set JTAG/SWD to an enabled state.
6. Malfunction of the EVRICA Unit
With the EVRICA unit power ON and the target system power OFF, check the LEDs on the EVRICA unit.
The unit is functioning normally if the LEDs are in the following states:
| LED | Status |
|---|---|
| POWER | Red (solid) -> Green (solid) |
| STATUS1 | Green (solid) |
| Others | Off |
