新做的板子，用CCS对335X进行调试，DEBUG时报错(Error -1204 @ 0x3D5B) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation pa

你好：

      我新做了一块板子用的是3358的片子，采用的DDR2和NAND FLASH ，现在用CCS进行DEBUG时报错

(Error -1204 @ 0x3D5B)
Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 5.1.232.0)

我进行Test Connection 测试显示

显示没问题。

我板子 PWRONRESTn 和RTC_PWRONRESTn由FPGA提供，RTC_PWRONRESTn画图时没注意由FPGA的3V3的IO输出与要求不符合，要求为1V8，请问怎么排除问题。
