How to check PTM trace from the ETB without using JTAG or other adaptor

G1_Chang over 5 years ago

Hello. Im using I.MX6 solox Board from NXP Cooperation. This I.MX6 solox has a Arm Cortex-A9 processor. What I am trying to do is Tracing PTM which will be stacked up in the ETB buffer. I also used Zynq 7000 zc706 which has two Arm Cortex-A9 processors. In Zynq board, I could check the PTM trace from the ETB buffer very well. BUT, with IMX6 solox board, i only cannot trace the PTM from the ETB buffer. The only thing that i can see from the ETB buffer is like below 'ffffffff 08010000 00000000 00000000' So.. Is there something that i have to do 'special settings' for tracing the PTM from the ETB buffer??
