Understanding xbsak status --lapc

Hi,

I am using SDx 2017.4.

Since my application is hanging  I added the option LAPC (Light AXI Protocol Checkers):

Krnl_GA_LDCLFLAGS+=--dk protocol:Krnl_GA_1:all

 

I would like to understand the LAPC output ("chan_igl" is one pipe):

...
CU Name: Krnl_GA_1 AXI Port: chan_igl Invalid codes read, skip decoding
CU Name: Krnl_GA_1 AXI Port: m_axi_gmem Invalid codes read, skip decoding
...

 

I wonder if "invalid codes read" mean that my LAPC configuration is wrong?

or

does it mean that the hang might be caused because that pipe "chan_igl" is stalled?

 

I am following UG1281 but I couldn't find any info about such output.

Any help would be appreciated!


Best,

Did you set app_debug in your sdaccel.ini?

[Debug]
app_debug=true
