看到TI的官方手册上是这样解释的：The VC5503/VC5507/VC5509/VC5509A bootloader supports boot from SPI EEPROMs or a device operating as an SPI slave that emulates the appropriate format. The bootloader supports SPI EEPROMs based on 16-bit byte addresses (up to 64k bytes) as mode BOOTM = 1001b.The bootloader supports SPI EEPROMs based on 24-bit byte addresses (up to 16M bytes) as mode BOOTM = 0001b.

        这意思是说：如果BOOTM设置为1001 ，那么以SPI形式外扩的FLASH烧写程序的大小就有64K这个限制，而如果把BOOTM设置为0001，他的限制就放大到16M吗？？
