[原创] 将新唐调试器改造成通用CMSIS-DAP（待测试）

le062 2015-8-11 12:09 楼主

这两年新唐白送了不少开发板，每块板子上都集成了一个Nu-Link，这个东西现在只能调试新唐自家的芯片。给它做一个CMSIS-DAP的固件，就可以兼容很多其他处理器。简单说下移植步骤： 1 主要参考"CMSISDAP-DL-00001-r0p1-00rel0.zip"和“NUC100_120BSPv3.00.002” 2 移除keil的rtl系统，裸奔，IAR编译 3 使用新唐bsp中的usb库 4 先只支持HID，CDC和MSC未使能 5 插上电脑，可识别。但由于不熟悉CMSIS-DAP，没进一步测试源码、原理图及参考资料 github.com/le062/CMSIS-DAP 如果你有两块Nu-Link-Me V2.0，可以使用烧录下面这个编译好的固件

如果要还原，可以在Nuvoton Tools\ICPTool\Nu_Link下面找到原厂固件。 IO表：

上午花了点时间调试。
解决了三个bug
1：增加dap_xxx 宏
2：修正usb字符串描述符
3：修正usb hid in/out传输逻辑

现在测试，usb之间已有swd sequence和swd transfer数据，但是可能因为底层io驱动有问题，我这边应答的数据是有问题的。
这个地方需要在检查下io是否正常，当然最好能找个能用的cmsis-dap看下它的usb数据和swd电平逻辑

修正了"AN"版本上GPIO寄存器使用方法

现在可以下载程序和调试了，不过iar下速度很慢
