DM648 为什么加了User-Define Device后,进不了main了?编译下载都没什么问题,对于User-Define Device的配置见附件。
另外我直接运行DM648DVSDK内的例程也是如此进不了main函数,所以我把CCS信息也截图出来,请帮忙看看啊

好像下面这个时钟的问题,你的板子上,这个时钟有信号吗?
A software port reset may be performed on the entire video port by setting the VPRST bit in VPCTL. This
behaves identically to the peripheral bus reset except that it does not clear the PEREN bit in PCR. This
reset:
· Performs a reset on all port logic (channel logic may stay in reset until port input clock pulses occur).
· Self-clears the VPRST bit to 0 but leaves the VPHLT bit set. The VCLK1 input must be clocking in
order for this reset to take effect.
NO NO4 说:DM648的VP0至VP4都有CLK0和CLK1连个时钟,搜索DM648的Datasheet,没有发现VCLK1这个Pin脚,然后我的VP4设置为输出port。
时钟信号上有时钟输出吗?
NO NO4 说:I2C配置,使用IOM_Fxns,��序可以跑下去
因为I2C把外部的ADC配置好后,就有时钟输出了。
NO NO4 说:init function是可以进去的,完成VP的初始化
不是死机,是在while等待状态,状态不置位,当然不会往下执行。
对于我的提示,多想一会儿,多试一会儿再回复。
