Hi,
I am using Arm Development Studio IDE to remotely debug an application with gdbserver, when I launch the application I have this message: thread 3700 #1 stopped (reserved) and it doesn't let me debug step by step.
How can I remove the reserved restriction and debug it with privileges?
Hi iiiv,
The "RESERVED" mode you are seeing is the Reserved mode in AArch32, which is not a valid mode.Your iMX8 is an Armv8-A target, so you will need an AArch64 gdbserver. Also, in the Debugger's Debug Configuration dialog, you must select Linux Application Debug > Application Debug > Connections via AArch64 gdbserver - see screenshot.
I can reproduce the "stopped in RESERVED mode" you saw if I select "Connections via gdbserver" instead of the (correct) "Connections via AArch64 gdbserver".Hope this helps,Stephen
Hi Stephen,
Is there a way to debug TrustZone or can you give me some indication of how to do it? (I try to debug OPTEE)
Thanks
