TDA4VL-Q1: ccs cannot connect to TDA4VL

I later used CCS12.81 to try to connect to the TDA4VL development board. The same error occurred. Please help me check if there is any error in my operation.

I created a CCSproject with the following configuration

I configured the simulator and chip in CCXML and configured the gel of CORTEX_M4F_0 in the advanced page.

After saving, I clicked Test Connection and the output log was as follows

The connector and development board connections I used are as follows.

Hello, Are you able to connect using the onboard xd110 JTAG connection?

I tested using XDS110 configuration, this should be OK.

I successfully started the project, but I can only connect to MCU_Cortex_R5_0 and cannot connect to MAIN_Cortex_R5_0_0. Can you help me troubleshoot the following?

When I try to connect to MAIN_Cortex_R5_0_0 I get error -1170

Hi，

I use the same configuration to connect another target board, and it can successfully connect to every core. Can this mean that the SOC of this target board that cannot connect is damaged?

Hi，

I asked our hardware colleagues and they said that the VDD_WK_0V8 of this board has been cut off. Does cutting it off have any effect on the connection between MCU2_0 and Linux?

It is connected to the P20 pin of the SOC

How is this connected on the other target board, which you said is successfully connected to all cores? Pls compare the schematics b/n working and non-working boards and see if this is the only difference.

We have to check the impact of cutting this with our hardware folks. So let us know the above first before we go and ask.

Thanks.

Hi,

This problem has been solved now. The PMIC on the abnormal board was damaged, which caused this problem. I solved it after replacing it with a new PMIC.

Thanks.
