Then it will either (1) jump to the program in DRAM at address 0x2000:0000 (2) wait for you to break in with GDB to debug the SDRAM program. These different behaviors are controlled by SAMA5D4EK_DRAM_START. NOTE: If you use this boot loader, then your program must be built at origin 0x2000:0000, not at 0x2000:8000 as is customary with U-Boot. config SAMA5D4EK_DRAM_START bool "Start DRAM program" default n depends on SAMA5D4EK_DRAM_MAIN ---help--- The default behavior of the DRAM boot program is to initialize the DRAM, then patiently wait for you to break into the program with GDB. An alternative behavior is enabled with this option: If SAMA5D4EK_DRAM_START is defined, then it will not wait but will, instead, immediately start the program in DRAM. config SAMA5D4EK_AT25_MAIN bool "Build at25_main" default n depends on SAMA5_BOOT_ISRAM ---help--- at25_main is a tiny program that runs in ISRAM. at25_main will enable SDRAM and configure the AT25 Serial FLASH. It will prompt and then load an Intel HEX program into SDRAM over the serial console. If the program is successfully loaded in SDRAM, at25_main will copy the program at the beginning of the AT26 Serial FLASH. If the jumpering is set correctly, the SAMA5D4 RomBOOT loader will then boot the program from the serial FLASH the next time that it reset. config SAMA5D4EK_AT25_PROGSIZE int "AT25 partition size" default 131072 depends on SAMA5D4EK_AT25_MAIN ---help--- This is the size of the partition at the beginning to the AT25 serial FLASH that will be used to hold the boot program. Since this program must run from SRAM, there would be no purpose int making this size any larger than the size of the internal SRAM. config SAMA5D4EK_DRAM_BOOT bool "Using DRAM boot loader" default y depends on SAMA5_BOOT_SDRAM && !SAMA5D4EK_DRAM_MAIN && !SAMA5D4EK_AT25_MAIN ---help--- Select this option if you are going to boot using the sdram_main bootloader (created with SAMA5D4EK_DRAM_MAIN=y). This selection will simply origin your program at 0x2000:0000 as required by the sdram_main bootloader (vs. 0x2000:8000 as required by U-Boot). config SAMA5D4EK_NAND_BLOCKMOUNT bool "NAND FLASH auto-mount" default n depends on NSH_ARCHINIT && SAMA5_EBICS3_NAND ---help--- Automatically initialize the NAND FLASH driver when NSH starts. choice prompt "NAND FLASH configuration" default SAMA5D4EK_NAND_NXFFS depends on SAMA5D4EK_NAND_BLOCKMOUNT config SAMA5D4EK_NAND_FTL bool "Create NAND FLASH block driver" depends on MTD && MTD_NAND ---help--- Create the MTD driver for the NAND and "wrap" the NAND as a standard block driver that could then, for example, be mounted using FAT or any other file system. Any file system may be used, but there will be no wear-leveling. NOTE: This options is not currently recommended. There is not now NuttX file system that can handle the NAND back blocks or performs wear-leveling other than NXFFS and NXFFS does not use a block driver but, rather, operates directly upon the NAND MTD device. config SAMA5D4EK_NAND_NXFFS bool "Create NAND FLASH NXFFS file system" depends on MTD && MTD_NAND && FS_NXFFS && NXFFS_NAND ---help--- Create the MTD driver for the NAND and mount the NAND device as a wear-leveling, NuttX FLASH file system (NXFFS). The downside of NXFFS is that it can be very slow. NOTE: NXFFS is recommended because (1) it can handle the NAND back blocks and (1) performs wear-leveling. endchoice # NAND FLASH configuration config SAMA5D4EK_AT25_BLOCKMOUNT bool "AT25 serial FLASH auto-mount" default n depends on (NSH_ARCHINIT || SAMA5D4EK_AT25_MAIN) && SAMA5_SPI0 && MTD_AT25 ---help--- Automatically initialize the AT25 SPI FLASH driver when NSH starts. choice prompt "AT25 serial FLASH configuration" default SAMA5D4EK_AT25_FTL depends on SAMA5D4EK_AT25_BLOCKMOUNT config SAMA5D4EK_AT25_FTL bool "Create AT25 Serial FLASH block driver" ---help--- Create the MTD driver for the AT25 and "wrap" the AT25 as a standard block driver that could then, for example, be mounted using FAT or any other file system. Any file system may be used, but there will be no wear-leveling. config SAMA5D4EK_AT25_CHARDEV bool "Create AT25 Serial FLASH character driver" ---help--- Create the MTD driver for the AT25 and "wrap" the AT25 as a standard character driver that could then, for example, via simple open, close, read, write file system operations. There will be no wear-leveling in this configuration. config SAMA5D4EK_AT25_NXFFS bool "Create AT25 serial FLASH NXFFS file system" depends on FS_NXFFS ---help--- Create the MTD driver for the AT25 and mount the AT25 device as a wear-leveling, NuttX FLASH file system (NXFFS).
