网上买的开发板，AM3352，想通过jtag烧写nandflash，CCSv6.2。根据后面这个说明操作，processors.wiki.ti.com/.../AM335x_CCS_Flashing_Tools_Guide。 GEl文件是在AM335x 15x15 EVM v1 5.zip的基础上改的。
在 "Connect Target"之后出现如下内容：
CortxA8: Output: **** AM335x EVM v1.5 Initialization is in progress ..........
CortxA8: Output: **** AM335x ALL PLL Config for OPP == OPP100 is in progress .........
CortxA8: Output: Input Clock Read from SYSBOOT[15:14]: 24MHz
CortxA8: Output: **** Going to Bypass...
CortxA8: Output: **** Bypassed, changing values...
CortxA8: Output: **** Locking ARM PLL
CortxA8: Output: **** Core Bypassed
CortxA8: Output: **** Now locking Core...
CortxA8: Output: **** Core locked

CortxA8: Output: **** AM335x EVM v1.5 Initialization is Done ******************
但是然后执行“script”->"AM335x System initialization"后就出差了，
CortxA8: Output: **** AM335x EVM v1.5 Initialization is in progress ..........
CortxA8: Output: **** AM335x ALL PLL Config for OPP == OPP100 is in progress .........
AM335x_EVM_v1_5_Initialization() cannot be evaluated.

请问着是什么问题？
