TI官方OAD off chip，校验是从哪里开始计算的，OAD boot程序里面是怎样比对校验的？

RT

Viki Shi：

Unlike OAD Image for On-chip OAD, OAD Image for Off-chip OAD doesn’t have the metadata embedded. Instead, it has just 2-byte CRC and 14-byte 0xFF’s in the beginning. Anyway, the first 16 bytes can be ignorable.

更具体的描述请参考CC2640 BLE OAD User's Guide
