你好,
谢谢你的快速回复。
在此期间,我一直在寻找自己的两个版本的FX2(128针对56针)和两个板的差异。
设置之间有一个显著的区别:128引脚开发板(工作)是总线供电,56针(不工作)板是自供电的。这可能解释GPIIFITIE()在像素时钟稳定之前被调用…我来查一下。
还有一件事引起了我的注意,我正在检查GPIF设计器中波形的配置。
我的波使用TCXPIER/RDY5信号。在启动波之前,我正在设置期望的转换计数,并且在波中,我正在检查TCXPIR信号以再次切换到空闲状态。但是,当我将GPIF设计器中的部分设置更改为56引脚的FX2时,该信号在框图中不再可用。
我没有发现任何具体的信息在TRM,你能告诉我,如果TCXPiar信号是可用的FX2LP与56针?
谢谢你的任何帮助。

Hi,
thanks for the quick reply.
In the meantime, I've been searching myself for the differences of the two versions of the FX2 (128-pin vs. 56-pin) and the two boards.
There is one significant difference between the setups: the 128-pin development-board (working) is bus-powered and the 56-pin (not working) board is self-powered. That would maybe explain that the GpifInit() would get called before the pixel-clock gets stable... I will check that.
There is one other thing, that caught my attention, while I was checking the configuration of the wave in the GPIF-Designer.
My wave uses the TCxpire/RDY5 signal. Before I start the wave, I'm setting the desired transation count and within the wave I'm checking the TCxpire signal to switch to the idle-state again. However, when I change the part-setting in the GPIF-Designer to the FX2 with 56-pin, this signal is not available anymore in the block-diagram.
I didn't find any specific information in the TRM, can you please tell me, if the TCxpire signal is available on an FX2LP with 56-pins?
Thanks for any help in advance.
