AWR2243: cascade metaImage 下载问题

Part Number: AWR2243


硬件平台是TI官网的级联顶板,底板是自己画得板子,在最开始spi通信的时候,首先接到了一个异步消息(MSGID为0x280,MSGDATA域中的SubBlockl ID为0x5000,其中MSS_POWERUP_STATUS字段为0x40,查表显示是METAHEADER_NOT_FOUND),于是我就自己发送AWR_DEV_FILE_DOWNLOAD_MSG这个消息,SubBlockID为0x4080,分批次分包把MetaImage.h下载进去,但是在发送前几个包的时候,都能收到ACK回应,但是发送的中间的时候,给我回复了一个ERROR信息,其中API_RESP字段为0x0004,说是Incorrect Sub block Length,但是我每一包的Sub Block长度都一样都是232byte,所以现在不知道哪里有问题,我想知道AW2242是如何判断这个长度有问题的?
