The board utilities folder contains CCS based NAND writer utility and Serial
Flash utility for programming the bootloader binaries on the EVM.

ccs/dm365: Contains NAND Eraser, NAND writer and UBL binaries for DM365
device. It also contains UBL binaries for different ARM/DDR speed combinations
along with the binaries for the default (ARM: 297MHz, DDR: 243MHz) combination.

ccs/dm355/legacy: Contains NAND writer and UBL binaries for DM355 Rev A
silicon; The RBL expects the NAND writer to program the bootlaoder binaries in
the legacy layout - 512+16, 512+16, 512+16, 512+16.

ccs/dm355/standard: Contains NAND writer and UBL binaries for DM355 Rev C
silicon;
The RBL uses the standard layout and thus expects the bootloader binaries
to be programmed in the standard layout - 2048+64 or 4096+128.

ccs/dm644x: Contains NAND writer, NOR writer and UBL binaries for DM6446
device.

serial_flash/dm365: Contains Serial flash utility for the host to flash the UBL
and u-boot binaries on DM365 EVM.

serial_flash/dm355/legacy: Contains Serial flash utility for the host to flash
the UBL and u-boot binaries on DM355 EVM with Rev A silicon revision.

serial_flash/dm355/standard: Contains Serial flash utility for the host to
flash the UBL and u-boot binaries on DM355 EVM with Rev C silicon revision.

serial_flash/dm644x: Contains Serial flash utility for the host to flash the
UBL and u-boot binaries on DM644x EVM.

All the above utilities require u-boot binary which can be obtained from the
release.
