aducm320和aducm320烧写问题

最近项目上使用了一个ADUCM320芯片,烧写正常,但是最近采购芯片的时候采购成ADUCM320I,发现程序烧写不进去,但是看手册只有下载接口那块有区别,一个是mdio,一个是i2c,但是我下载的时候用的都是SW接口,按理说不应该出现烧写不进去的问题。现在发现ADUCM320的FLASH地址0x407e8读取出来的信息和ADUCM320I的不一样是,是不是ADUCM320I,我买到假芯片了。

读取出来的数据截图如下:

  • Hi Shuai Yang,

    ADuCM320 and ADuCM320I is technically the same. The only difference between them is the downloader used which is MDIO downloader for ADuCM320 and I2C downloader for ADuCM320I.

    The information from the flash address 0x407E8 that you are reading for both is a traceability information of the part.

    Can you attach here a picture of the marking of the top die for the ADuCM320I so we can check? Thanks!

    Regards,
