Abstract: The present disclosure is directed to firmware block dispatch based on fusing. A device may determine firmware blocks to load during initialization of the device based on fuses set in a processing module in the device. A firmware module may comprise at least a nonvolatile (NV) memory including boot code and a firmware information table (FIT). During initialization the boot code may cause the processing module to read fuse information from a fuse module and to determine at least one firmware block to load based on the fuse information. For example, the fuse information may comprise a fuse string and the processing module may compare the fuse string to the FIT table, determine at least one pointer in the FIT table associated with the fuse string and load at least one firmware block based on a location (e.g., offset) in the NV memory identified by the at least one pointer.

Abstract translation: 本公开涉及基于融合的固件块调度。 设备可以基于设备中的处理模块中设置的熔丝来确定在设备的初始化期间加载的固件块。 固件模块可以包括至少包括引导代码和固件信息表（FIT）的非易失性（NV）存储器。 在初始化期间，引导代码可能导致处理模块从保险丝模块读取熔丝信息，并且基于熔丝信息来确定要加载的至少一个固件块。 例如，熔丝信息可以包括熔丝串，并且处理模块可以将熔丝串与FIT表进行比较，确定与熔丝串相关联的FIT表中的至少一个指针，并基于位置加载至少一个固件块 （例如，偏移）在由至少一个指针所识别的NV存储器中。
