CCS/AM4377: Debug connection over Segger J-Link not allowed

Part Number: AM4377
Other Parts Discussed in Thread: SEGGER, AM4379

Tool/software: Code Composer Studio

I am trying to debug an AM4377 board ( MYIR MYD-C4377-PRU) over Segger J-Link. When I select Segger J-Link the list in "Board or Device" gets filtered (compared to XDS110 for example) and none of AM437X variants is present. Still, AM33xx SoC are there.

Is there a way to get over this problem? Does it needs support from Segger, or newer version of CCS? I saw a related question about AM57xx and I understand the without Segger cooperation it will not work.

But in AM43xx there are no additional core types (as compared to supported AM33xx).

I am using the latest  Version: 9.0.1.00004 of CCS with all updates as of today.

  • Krasi,

    Support for this device would need to come from Segger.  There are core differences between AM4377 and AM335x (Cortex A9 vs A8 for example).  However in general the main issue is that to support a device Segger needs to validate on that device and update any necessary configuration scripts.  Typically they will do this based on if there is enough customer demand.

  • Thank you, I expected this. 

    On Segger's list of supported devices I see that AM4379 is present (but only it - no mention of other AM43xx members). So from technical point of view all is available but maybe needs tailoring for 4377.

    I suppose it it internal information but if Segger releases support for this chip, would it require validation and changes in CCS to get the new entries in the list?

  • Krasi,

    They can push an update to CCS.  They do that periodically.  It will show up when you check for updates from the Help menu.  If they have support for AM4379 then adding support for AM4377 is likely pretty straight forward.  Main difference looks to be the graphics core.
