Flash command internally uses DFU, and Fastboot command initialization is modified to add DFU and partition initialization Added oem format functionality for GPT table creation partitioning code is added as disk/part_fastboot.c for better usability Fastboot flash command code is enabled and being tested on BeagleBone Black. OMAP3 Beagle configuration is modified to fix the build errors, but this configuration needs to be updated as per the flash functionality.
