Using ILA with PetaLinux 2017.3 for debug causes Linux to Hang

I recently came across this issue, basically I was trying to use the JTAG debugger on a ZCU102 to connect to my ILA.

 

The issue manifest as Linux sometimes not booting, sometimes booting and running for minutes, then hanging and various hangs in between.

 

I eventually found the answer in this AR 69143

 

 

To use ILA with Petalinux 2017.1 & later you must set cpuidle.off=1

Hi

 

Did the below AR 69143 didnt fix your issue? Currently we have only this work-around and we will be providing the fix to this issue ASAP in our upcoming releases without having to go for disabling CPU IDLE

Hi Shabbir,

 

The AR did fix the issue, I created this post so there was an online reference for anyone else having the same issue.

 

As we were in early debug of our system, the problem manifest itself so randomly we did not suspect the JTAG was the issue.

 

Best regards,

Andy
