Escaping Infinite Reset

PHPoC basically runs scripts when it boots up. Therefore, it is possible that a P4S-341 cannot be
escaped from infinite reboot when script contains system command such as "reboot". To solve this
problem, it is required to stop the running script.
Refer to the following.

Entering ISP mode

1.

Make P4S-341 to enter ISP mode by supplying power while pressing FUNC button. In the ISP
mode, you can access to PHPoC by PHPoC Debugger without running a script.

Connect to PHPoC

2.

Connect a PC to PHPoC via a USB cable and connect to the port via PHPoC Debugger. A
message window related with ISP mode will be popped up.

Reboot PHPoC

3.

Reboot PHPoC by using "Reboot a product" menu in PHPoC Debugger. After rebooting,
PHPoC stops running script even it is not in the ISP mode.

Correct source code

4.

Correct the source code to prevent infinite reboot state.
