The hawkboard comes with a 128MiB Nand flash and a 128MiB -DDR SDRAM along with a host of other controllers. - -The hawkboard is booted in three stages. The initial bootloader which -executes upon reset is the Rom Boot Loader(RBL) which sits in the -internal ROM of the omap. The RBL initialises the memory and the nand -controller, and copies the image stored at a predefined location(block -1) of the nand flash. The image loaded by the RBL to the memory is the -AIS signed spl image. This, in turns copies the u-boot binary from the -nand flash to the memory and jumps to the u-boot entry point. - -AIS is an image format defined by TI for the images that are to be -loaded to memory by the RBL. The image is divided into a series of -sections and the image's entry point is specified. Each section comes -with meta data like the target address the section is to be copied to -and the size of the section, which is used by the RBL to load the -image. At the end of the image the RBL jumps to the image entry -point. - -The secondary stage bootloader(spl) which is loaded by the RBL then -loads the u-boot from a predefined location in the nand to the memory -and jumps to the u-boot entry point. - -The reason a secondary stage bootloader is used is because the ECC -layout expected by the RBL is not the same as that used by -u-boot/linux. This also implies that for flashing the spl image,we -need to use the u-boot which uses the ECC layout expected by the -RBL[1]. Booting u-boot over UART(UART boot) is explained here[2]. - - -Compilation -=========== -Three images might be needed - -* spl - This is the secondary bootloader which boots the u-boot - binary. - -* u-boot binary - This is the image flashed to the nand and copied to - the memory by the spl. - - Both the images get compiled with hawkboard_config, with the TOPDIR - containing the u-boot images, and the spl image under the spl - directory. - - The spl image needs to be processed with the AISGen tool for - generating the AIS signed image to be flashed. Steps for generating - the AIS image are explained here[3]. - -* u-boot for uart boot - This is same as the u-boot binary generated - above, with the sole difference of the CONFIG_SYS_TEXT_BASE being - 0xc1080000, as expected by the RBL. - - hawkboard_uart_config - - -Flashing the images to Nand -=========================== -The spl AIS image needs to be flashed to the block 1 of the Nand -flash, as that is the location the RBL expects the image[4]. For -flashing the spl, boot over the u-boot specified in [1], and flash the -image - -=> tftpboot 0xc0700000 <nand_spl_ais.bin> -=> nand erase 0x20000 0x20000 -=> nand write.e 0xc0700000 0x20000 <nand_spl_size> - -The u-boot binary is flashed at location 0xe0000(block 6) of the nand -flash.
