DLPC4422无法启动,flash烧写文件为官网Flash_DDPC4422_DLP650NE_LED

Other Parts Discussed in Thread: DLPC4422, DLP650NE

做了一块DLPC4422单板,flash使用的是mxic公司的MX29LV640EBTI-70G芯片,离线烧写官网Flash_DDPC4422_DLP650NE_LED.img文件,然后贴装到单板上,现在dlpc4422无法启动,无法通过USB链接到PC dlpc4422 gui,驱动显示设备异常,示波器测量dlpc4422的 oe cs we管脚感觉dlpc4422在反复读flash.

我发现官网参考文件1080P_LASER_TV使用的flash是spansion公司的S29JL064J70TFI000 这个芯片,请问dlpc4422对flash型号有要求吗??

DLP650NE-8.0-windows-installer官网这个中flashparameter.txt文件干嘛用的呢,里面描述了很多的flash型号
