Part Number: TMS320F28335
Other Parts Discussed in Thread: UNIFLASH

采用全部搬运方式（此时RAM占用97%），但频繁出现烧不尽程序的时刻，需要多次重复烧录，请问该如何解决

上边是烧录时使用的CMD代码

您好

我对上述问题不清楚。你的意思是不是每次通过JTAG将.out文件加载到设备时都不会正确？

我最初的想法是，如果几乎所有的闪存都被使用，那么总擦除时间将是最大的，每个扇区最多可达15秒。CCS/Uniflash应自动遵守此最大时间；但如果客户自己调用API（比如引导程序编程闪存），他们可能没有使用每个扇区的最大数量，这可能会导致设备无法正确擦除。

如果我正确理解了这个问题，请告诉我。

您好

"你的意思是不是每次通过JTAG将.out文件加载到设备时都不会正确？"

是的，下载时程序会下载不进去或者下载完无法运行，当出现下载完不能运行时需要按复位按键后才能运行

您好

客户是否尝试过CCS及其闪存插件的相同实验？我想知道Uniflash的某些设置是否配置不正确，无法在闪存刻录后运行程序。如果重置后设备工作正常，那么我认为闪存编程正确；这可能不是闪光问题。

如果可能的话，请通过CCS/JTAG告诉我上述情况。
