今天，仔细阅读了AM335x CCS Flashing Tools Guide，发现其中有句话不是很懂：
Due to heavy pin-muxing, NAND flash is only available on few AM335x EVM and in few profiles. The user has to make sure that the d profiles have been properly selected to enable NAND before flashing the image to NAND. On unsupported profiles NAND flash tool will fail to detect NAND.
这句话是指并不是所有的AM335X EVM支持NAND 烧写吗？至于这个d profiles是什么呢？d profiles用于选择时能NAND。
