openjtag在调试LPC1788时错误：JTAG-DP STICKY ERROR？

如题，请高手指点。

贴出配置脚本

楼主自讨苦吃，那么多工具不用，用openocd？
那个错误是ARMV7 ADIV5接口中DP模块的错误，具体什么错误，要看代码，是寄存器的哪一位出错。

在想把led.bin文件烧写到0x1ffff进行测试时出错：
    load_image led.bin 0x1ffff
    JTAG-DP STICKY ERROR
    MEM_AP_CSW 0x23000050, MEM_AP_TAR 0x1f000

这个主要是在工业生产和商品进出口时考虑到一些版权问题。现在是对就产品升级，这只是一种选型和尝试。不知道是否可行，在ubuntu下开发，有没有其他种选择呢？

楼主用j-link吧，有linux版本

最后发现这个错误是因为在烧写前没有执行擦除命令造成的，先擦除芯片，然后在烧写，就没有这个问题了。
