EVMK2H大小端问题

在手册上看到EVMK2H只有两种启动方式

No Boot/JTAG DSP Little Endian Boot mode

For Rev 0B EVM, the setting is as follows

  SW1 - 4(ON) 3(ON) 2(ON) 1(OFF) 

For Rev 1.0 EVM, the setting is as follows:

  SW1 - 1(OFF) 2(OFF) 3(OFF) 4(ON)

SPI Little Endian Boot mode

For Rev 0B EVM, the setting is as follows:

  SW1 - 4(ON) 3(ON) 2(OFF) 1(ON) 

For Rev 1.0 EVM, the setting is as follows:

  SW1 - 1(OFF) 2(OFF) 3(ON) 4(OFF)

请问为什么都是小端模式？

难道EVMK2H不支持大端？
