Hi Leo Yan,
My apologies for the multiple emails.
It's no matter.
On a separate topic from coresight discovery, the new patch I have applied have resulted in failure to activate the etm drivers for tracing.
The above result can be seen here:
# echo 1 > ec036000.etf/enable_sink # echo 1 > ed440000.etm/enable_source # cat ed440000.etm/enable_source 0
I might be doing something wrong. Any guidance will be appreciated.
I think you have missed some patches for DT binding. Please see enclosed tar file which contains the DT binding.
After download it, you could use below command to apply them on the git tree:
$ tar zxvf cs_dt_binding.tgz $ cd $kernel $ git am $path/to/cs_dt_binding/*
Could you confirm you are using which kernel versio (4.14 or 4.19)?
Thanks, Leo Yan
