DM6467 GEL文件配置PLL问题

我最近在调试DM6467，平台CCS6.0+xds200。在配置PPL的时候会出现如下问题：
ARM926: GEL Output:DaVinci HD1080p ARM Startup Sequence

ARM926: GEL Output: Disable IRQ/FIQ
ARM926: GEL Output: Flush Cache
ARM926: GEL Output: Disable MMU
ARM926: GEL Output: Enable Instruction Cache.

ARM926: GEL Output: Setup PinMux…ARM926: GEL Output: [Done]
ARM926: GEL Output: Setup Power Modules (All on)…ARM926: GEL Output: [Done]
ARM926: GEL Output: Setup PLL0ARM926: GEL Output: (DSP = 594 MHz +ARM926: GEL Output: ARM = 148 MHz +ARM926: GEL Output: Onchip Oscillator)…ARM926: GEL Output: [Done]
ARM926: GEL Output: Setup PLL1  ARM926: GEL: Error while executing OnTargetConnect(): Driver did not attempt to read 0x01C40D00 at (*(pll_ctl)&=~(0x0002)) [davincihd1080p_arm.gel:718] at setup_pll_1(0, 17, 0) [davincihd1080p_arm.gel:840] at Setup_DDR_396_MHz() [davincihd1080p_arm.gel:44] at OnTargetConnect() .

在这个例子中PLL0能够配置，但是配置PLL1的时候出现这个问题，好像是配置PLL之后ARM和仿真器断开失去联系了。请问大家怎么解决？谢谢！

你好，

是你们自己做的板子么？如果是，能否检查一下电源，我怀疑是电源不稳定，看看电源的最低/最高电压是否在spec范围内。
