Dear Everyone.
I solved callout_debug_xxxxx.S and I looked at another kernel debugging
message like the below log.
What happens?
Unfortunately, I don't know where is the problem ?
Please help me.
Best regards.
Pusik.

QNX Porting problem on ARM926EJ-S-based SoC platform

Re: QNX Porting problem on ARM926EJ-S-based SoC platform
Hello.
I got some information of my status by TRACE32 ARM ICD.
The below assembler code is my status.
I guess that there is some problem in callout_reboot_xxxxx.S but I need some
hint.
Actually, I don't want to use WatchDog scheme.
Please give me a hint.
Best regards.
Pusik.

I got some information of my status by TRACE32 ARM ICD.
The below assembler code is my status.
I guess that there is some problem in callout_reboot_xxxxx.S but I need some
hint.
Actually, I don't want to use WatchDog scheme.
Please give me a hint.
Best regards.
Pusik.

Dear Everyone.
I solved callout_debug_xxxxx.S and I looked at another kernel debugging
message like the below log.
What happens?
Unfortunately, I don't know where is the problem ?
Please help me.
Best regards.
