你好,
谢谢。我喜欢把一个小程序为SPI Flash还附加应用程序。引导程序加载应用程序到SRAM,然后应用程序启动,它是32bit GPIF模式设置。你明白了吗?
在32bit GPIF模式的SPI UART在相同的引脚连接到SPI MISO(uarttx!!!!!!)所以如果我想传递的SPI,然后切换和软件UART SPI?这是可能的吗?
有时,应用程序需要保存用户的具体信息,得到这些信息的SPI Flash应用程序运行时。
当做,

Hi,
thanks. I like to put a small bootloader into the SPI flash and also append an application then. The bootloader loads the application into SRAM and then the application starts and it is setup in GPIF 32bit mode. You understand?
The UART in GPIF 32bit mode is at the same pins as the SPI (UART TX is connected to SPI MISO!!!!). So if I like to transfer SPI, then I have to switch between UART and software SPI? Would this be possible?
Sometimes application needs to save user specific informations in SPI flash and also get that information while application is running.
