Uboot debug issue - No symbols defined

Peter M

I am using CCS Version: 6.1.3.00033

Uboot U-Boot 2013.10 (from SDK 7.0).

I followed the instructions from

processors.wiki.ti.com/.../Sitara_Linux_Training:_uboot_linux_debug_with_ccsv5 Error connecting to target&tisearch=Search-EN and watched the video at https://training.ti.com/kr/linux-board-porting-series-module-7-debugging-u-boot-jtag-ccs?cu=399066

Yet when I set a hardware break point on functions (for example, mmc_start_init in mmc.c), the processor halts (after I run "mmcinfo" at the console prompt).

But I get a "No source available for "0x8f76d784"", the disassembly window does not show my source.

I did what the instructions said and I loaded the symbols (u-boot) with the code offset (and data offset) set to the value displayed at relocaddr from the "dbinfo" command.

Anyway ideas on why I am unable to see my source when the hardware breakpoint occurs?

When I was debugging the SPL, it seems to work and does show the source when the breakpoint occurs.

I forgot to mention that we are building the uboot for the am335x.

The pictures above show that when a hardware breakpoint is set, the "Breakpoints" window only shows the address of the breakpoint. Not the line within the source. And when the breakpoint triggers, the "Debug" window doesn't show the calling stack.

And the top picture shows that there is "no source available ..." message

Hello Peter,
I will see if I can reproduce the issue in my environment. Can you point me to the location where you downloaded the SDK from? I want to make sure I use the same version.

thanks

Brad is correct (and it was mentioned in my original post) that its was based on the 7.0 SDK for the am335x.
Also, note that I am using CCS 6.1.3.00033.

This thread was taken off-line but to provide an update for those following the thread, there appears to be some regression with 6.1.3. Earlier versions of CCS appear to work fine as shown with 6.1.2 below:

A bug was filed against 6.1.3 for this issue. Bug ID: CCDSK-2004

Thanks

This issue has been fixed and the fix will be available in the next CCS version (6.2.0).

Thanks

Hello Ki-Soo,

is there a release date for CCS 6.2 in sight?

I'm currently working on uboot for a AM5728-based design and I'm facing the same issue.

Is there some kind of work arround?

Regards

Hello,
The 6.2.0 release date is currently end of this month.

We do have a beta release if you want to try it out. Send me a private message if you do.

Thanks

Hello Ki,

back from holiday, I wanted to check back for CCS v6.2.

Looks like it's not released yet. Any idea about a new release date?

It was released last Friday and is now available on the main CCSv6 page and Download pages.

Sorry for the delay.
