Unable to connect to DSPS device.

Thank you for the reply and excuse me for the delay.

>>Do you mean that you have the debugger hot attached and you are not able to connect?

Exactly (see "Picture_1.png" attached)

I note a "*** error 10: Syntax error" in the command prompt, when I launch the debugging session.

>> Could you please clarify it? Do you mean that you download the firmware into the SPI Flash?

I'm loading the hex file into the main SysRAM of the chip (see "Picture_2.png" and "Picture_3.png" attached) and the DIALOG_SPD device is detected (see "Screenshot_Android.png").

This is the complete command prompt output:

*** error 10: Syntax error

What do you think is wrong?

Thank you in advance,

Maurizio

Dear PM_Dialog,

thanks for the support.

I've successfully read and putted into practice the first part of tutorial 8.

Subsequently I've tried to perform the same steps in the sps_device project.

The first attempt failed. I've discovered that the default initialization file for the JLINK pointed in the "Option for target 'sps_device_580' --> Debug" tab was wrong.

The right one to point is "..\..\..\..\..\sdk_580\sdk\common_project_files\misc\sysram_case23.ini".

In this way, no more "*** error 10: Syntax error" raises in the command prompt output window.

In this project, unfortunately, the UART2 port is used as I/O terminal for the UART over BLE, so I cannot activate the "CFG_PRINTF" as described in the tutorial 8, but the debug starts in the KEIL IDE.

With this configuration, the DIALOG-SPS application is able to detect the device and all is properly working but the JLINK loses the connection preventing to perform real-time debugging from the IDE.

When the connection to the uC is lost, the command prompt output windows shows:

Perhaps any sleep mode enters making thus the JLINK connection falling down?

Is possible to perform a standard debug of this project?

Am I forced to use serial ports to debg?

What are the limitations/constraints in general?

Thank you very much indeed in advance,

Maurizio

Yes, thanks al lot!

In this way the debugger seems to properly work.

Could you pse send me some links to the debugging limitations / what to know in order to understand what are the debugging limitations and/or how sleep modes influence the behaviour of the code?

Regards,

Maurizio
