C66x bootloader相关知识



RBL(Rom Boot Loader)
C6678的片内ROM里有出厂时永久固化的bootloader叫RBL。RBL有i2c,EMIF,SRIO等六种启动模式,RBL只能加载核0,也就是主核的执行文件。这时候需要二级bootloader去加载其他几个核。

IBL( Inermediate Boot Loader)
MCSDK中提供的二级bootloader,存放于E2PROM中,当RBL配置为I2C启动模式时可以加载IBL。IBL有三种加载方式,分别为NAND,NOR和TFTP。
在用IBL进行多核加载时还需用到MCSDK中的MAD tools。
