大家好:
上面是我使用的GEL文件,在连接A8后,运行脚本“IS_DEVICE_GP_TEST”
对应输出:
CortexA8: Output: Device type is GPCortexA8: Output: Modena PLL EFuse are not corerctCortexA8: Output: DSP PLL EFuse are not corerctCortexA8: Output: SGX PLL EFuse are not corerctCortexA8: Output: IVA PLL EFuse are not corerctCortexA8: Output: L3 PLL EFuse are corerctCortexA8: Output: ISS PLL EFuse are not corerctCortexA8: Output: DSS PLL EFuse are corerctCortexA8: Output: Vid0 PLL EFuse are corerctCortexA8: Output: VID1 PLL EFuse are corerctCortexA8: Output: HDMI PLL EFuse are corerctCortexA8: Output: Audio PLL EFuse are corerctCortexA8: Output: USB PLL EFuse are corerctCortexA8: Output: DDR PLL EFuse are corerctCortexA8: Output: RAM LDO EFuse are not corerct
其中 ISS PLL初始化失败。
如何着手查看调试?
在调试CSI2接口发现上电标志位不能置位,一路查回开始部分。
还望解答

为神马会有EFuse的问题。这个和PLL没啥关系吧。。。你芯片和gel能不能对上啊

hi,wang
EFuse 是什么鬼?后来GEl又能跑了…也是醉了,没发现什么地方不一样,ISS 的CLock 通过了…
