Getting Cannot find any synchronization packet error
adhya3 opened this issue · comments
Hi,
I have cloned the ptm2human decoder for decoding etm v4 trace data . I'm using the below command to decode the data .
./ptm2human -e -i log_etm.atb -d --trcidr0 0x28000ea0 --trcidr8 0x0 --trcidr9 0x0 --trcidr12 0x0 --trcidr13 0x0
But after executing the script I'm getting the below mentioned error though I have set TRCSYNCPR value to 0x8 . Can you please let me know what I'm doing wrong here. Also please find the attached trace stream file.

ptm2human reads a special format data packets (from the ETB formatter).
Check the Figure 9.13 in the ARM CoreSight Technical Reference Manual. http://infocenter.arm.com/help/topic/com.arm.doc.ddi0314h/DDI0314H_coresight_components_trm.pdf
The format of your data packet is not matched.
0x00000000
0x00000000
0x80000000
0x04000101
...
So ptm2human could NOT decode these packets. (Maybe I should submit a change to prompt messages for this kind of problems.)
Seems like your are trying to feed in ETMv4 data directly.
