Hi Yang,

It is not clear what is the issue you are running into, from your description. It just looks like a statement and a tarbar of the binaries generated.

Can you paste a picture of the issue?

regards

Suman

HI TI

The phenomenon of this issue is: upon power-on and startup, the machine has a probability of getting stuck during the boot process.
The attached log is the issue generated by executing j7es_r5_dump_log.js on the CCS when the problem occurred.

Hi Yang,

What is the device type that you are using? Is this on the TI J721E EVM, or your own board?

Hi Yang,

What CCS Configuration are you using? There is an initialization script associated with DMSC for No-Boot method.

Please ensure that there are no initialization scripts associated with either of the DMSC or the MCU R5F cores if you are doing a regular boot.

Have you booted the device fully before trying this?

regards

Suman

Hello Suman,

The CCS configuration used is: 6.4. Debugging with HLOS running on A72 (Linux / QNX)

It is a normal boot without executing any scripts.
The device is fully booted up.

Hi Yang,

Your picture got cut-off. Are you trying to do the dump while connected to CCS like the picture shows?

Also, are you simply able to do the dump using the CCS Memory Browser to begin with?
