When initially debugging a device with the password locations in flash programmed (that is, secured), the emulator takes some time to take control of the CPU. During this time, the CPU will start running and may execute an instruction that performs an access to a protected ECSL area. If this happens, the ECSL will trip and cause the emulator connection to be cut. Two solutions to this problem exist:
1. The first is to use the Wait-In-Reset emulation mode, which will hold the device in reset until the emulator takes control. The emulator must support this mode for this option.
2. The second option is to use the “Branch to check boot mode” boot option. This will sit in a loop and continuously poll the boot mode select pins. You can select this boot mode and then exit this mode once the emulator is connected by re-mapping the PC to another address or by changing the boot mode selection pin to the desired boot mode.
2803x系统控制和中断中由上述描述,请问如上述第一条解决方案所述,要什么样的仿真器才具有使2803x系列芯片进入Wait-In-Reset emulation mode的功能,有推荐么?
有这种功能的仿真器是通过什么方式使目标器件进入Wait-In-Reset emulation mode这个模式?
