MSPM0L1306: Error connecting to the target: (Error -6305)

Check the debug probe configuration in Code Composer Studio (CCStudio). It should be correctly configured to communicate with the external MSPM0L1306 and  the settings should match your hardware setup.

Hi Beat,

Beat Brand said:

GND, +3.3V, SWDIO, SWCLK, NRST are directly connected from XDS110 to pinout-Board.

Could you share you partial schematic of the MSM0L1306, please inlcude VDD,VCORE,NRST, and SWDIO, SWCLK.

By the way, you could also try factory reset to recover the devcie: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1327840/lp-mspm0l1306-error--6305-prsc-module-failed-to-write-to-a-router-register-after-successful-factory-reset/5088986#5088986

Hello

The instructions in e2e.ti.com/.../5088986
did not get me any further. The factory reset only worked with the online tool:
dev.ti.com/.../

So let me show you my testing setup and how I have tryed to connect/programm the target.

The experimental setup

The Jumper-Pins GND, +3.3V, SWDIO, SWCLK, NRST from the launchpad are connected directly to the MSPM0L1306 SOT-16 (DYY), the remaining jumpers to XDS110 are left open.

Pin assignement:

NRST pin 4
+3V (VDD) Pin 5
GND (VSS) Pin 6
SWDIO Pin 11
SWCLK Pin 12

1st Test: Connecting and testing the target MSPM0L1306

- First, I imported the empty_mspm0l1306 project from the sdk into CCS:
C:\ti\mspm0_sdk_2_00_00_03\examples\nortos\CUSTOM_BOARD\driverlib\empty_mspm0l1306\ticlang

- In Sysconfig, I have changed the package type of the MSPM0L1306 to 'SOT-16(DYY)' and left the other settings at the default values and saved the entire project.

- I have tested the communication to the target with 'Test Connection' in the target configuration. It works without errors (protocol below).

- I connected the 'Non Debuggable Devices' (CS_DAP_0 and SEC_AP) of the target. It works also.
However, when I try to connect CORTEX_M0P on the target, the following message appears:

'CORTEX_M0P: Error connecting to target: (Error -6305) PRSC module could not write to a router register. (Emulationspaket 12.7.0.00130)'

Screenshot shows the CCS after connecting to the target:

Output protocol from testing the connection to the target ('Test Connection' in the target configuration):

2nd Test: Build Project and start debugging

- I closed all connections to the target, built the project and started debugging:



The following message appears while CCS tries connect to the MSPM0L1306
'CORTEX_M0P: Error connecting to the target: (Error -6305) PRSC module failed to write to a router register. (Emulation package 12.7.0.00130)'

Testing Results
The error (Error -6305) PRSC occure if a connection to CORTEX_M0P should be established.

--> How can I connect to CORTEX_M0P and what is the meaning of (Error -6305) PRSC ?

Thanks a lot

Regards
Beat

Hi Beat,

According to your PCB layout, there is no necessary capacitor on VCC/ VCORE / NRST (pull-up resistor).

Please check whether you implement them.

Hi Sal

Now I added the 10uF and 0.1uF capacitors between VSS and VDD and the 47k resistor from VDD to NRST

The connection to CS_DAP_0 and SEC_AP was successful:

But if I tryed to connect the CORTEX_M0P the message was the same:


I don't know what's going wrong. Is there any further information? Can I test which register fails to write?
The MSPM0L1306 is out of the box and has no password. 

Hi Brand,

Vcore is necessary for the MCU normally running. And better add the capacitor with NRST.

If it insists on unconnected, then please do a factory reset to the devcie.

You can get much guidance with search it in e2e thread. Below is an example you can refer:
