你好,在SW-TM4C-DRL-UG-2.0的ROM部分,有以下描述:
TARGET_IS_BLIZZARD_RA1
The application is being built to run on a Blizzard-class device,
silicon revision A1.
具体对应的是TM4C的哪个芯片的具体型号?

就具体一款芯片,我怎么知道是RA1,RA2,RA3,RB0,RB1?
你可以看看具体芯片上的丝印。据我所知,现在芯片上一般都是RB的版本,RA是以前的芯片版本。两个的改变基本上有很细小的差异,我没有对比过,但是你可以看看TI的版本差异手册,上面应该会给出各个版本间的具体差异的。
