We met the following error message while booting by PCI on DM6437.
We met thr following error message on CCS 3.3 using Single Step feature.
We read the data of Main Processor memory area (Freescale Processor) using PCI BUS
And these error message happen under the condition nearly "0" degree in case temprature.

Can't Single Step Target Program:
Error 0x00000020/-1202
Error during: Execution,
CPU pipeline is stalled and the CPU is 'not ready'. This means
that the CPU has performed an access which has not
completed, and the CPU is waiting. The target may need to be
reset. The user can choose 'Yes' to force the CPU to be 'ready'.
When this is done, the user will have the ability to examine
the target memory and registers to determine the cause of the
CPU stall. If CPU hang is caused by application and it has been
forced to be 'ready', the CPU should not be run without a reset.
Yes - - force CPU ready (might corrupt the code)
Disconnect - disconnect CCS so that it can be reset
Retry - attempt the command again.
Sequence ID: 14
Error Code: -1202
Error Class: 0x00000020
After the above error message, we met the following error messaga, when we read DDR2 content.

(My question)
When we met the above error message, does it show DM6437's core exceed 100% of the its perofomance?
Whta is the reason the following message happen?
To avoid the following error message, what issues we shoukd reconsider ?
