最近真在学习omapl138，刚拿到一块omapl138 lcdk，由于lcdk不板载仿真器，所以需要购买仿真器，由于本人学生一枚，买板子属于个人行为（学校没有款项支持），所以打算买一便宜的仿真器，所以选仿真器上出现了一定的问题，我最开始打算买xds100v2仿真器，但在有些仿真器销售的卖家得到的消息是，xds100v2不完全支持omapl138（好像dsp核可以下，arm支持不是很好），在ti的wiki上找到了一定的资料也是这个观点，所以我想来咨询一下，
问题一：现在的xds100v2的仿真器（不用像下面的那个首先将pll模块从gel提到执行代码中，然后调整频率，最后还检查cpld）能否支持omapl138？
问题二：ti estore上的行吗？
问题三：或者说xds100v3可以吗？
如果大家有其他便宜的仿真器型号提供（学生钱不多，560那种就不要提出来了），欢迎给出，谢谢。

Q: My XDS100v2 does not work reliabily with the OMAPL138 / DM365 / ARM926 core
- A: This can be caused by a variety of issues such as where the PLL is programmed to the use of Adaptive Clocking emulator. Usually, it is seen as a problem around the PLL setup. This is because the core PLL clock is changing. Example error message:
ARM9: GEL Output: Setup PLL0... ARM9: Trouble Writing Memory Block at 0x1c40900 on Page 0 of Length 0x4: 0x00000004/-2030 @ marker 1026 Error during: Register, Access to an unknown or invalid register was attempted. ARM9: GEL: Error while executing OnTargetConnect(): target access failed.
A couple of things to try:
- Setup the PLL by executing code (ex: UBoot, etc.) instead of using the GEL file. (preferred)
- Turn on adaptive clocking XDS100#Q:_How_can_I_turn_on_adaptive_clocking.3F and setup the timeouts to very slow. In this mode, it is still better to "run" the code and not "step" it.
- Make sure you have the latest CPLD version. To update the XDS100v2 CPLD, please see XDS100#Q:_How_can_I_update_the_CPLD_on_my_XDS100v2.3F
