Summary +========== +This is a quick instruction for setup Odroid boards based on Exynos4412. +Board config: odroid_config + +2. Supported devices +==================== +This U-BOOT config can be used on two boards: +- Odroid U3 +- Odroid X2 +with CPU Exynos 4412 rev 2.0 and 2GB of RAM + +3. Boot sequence +================ +iROM->BL1->(BL2 + TrustZone)->U-BOOT + +This version of U-BOOT doesn't implement SPL but it is required(BL2) +and can be found in "boot.tar.gz" from here: +http://dev.odroid.com/projects/4412boot/wiki/FrontPage?action=download&value=boot.tar.gz +or here: +http://odroid.in/guides/ubuntu-lfs/boot.tar.gz + +4. Boot media layout +==================== +The table below shows SD/eMMC cards layout for U-boot. +The block offset is starting from 0 and the block size is 512B. + ------------------------------------- +| Binary | Block offset| part type | +| name | SD | eMMC |(eMMC only)| + ------------------------------------- +| Bl1 | 1 | 0 | 1 (boot) | +| Bl2 | 31 | 30 | 1 (boot) | +| U-boot | 63 | 62 | 1 (boot) | +| Tzsw | 2111 | 2110 | 1 (boot) | +| Uboot Env | 2500 | 2500 | 0 (user) | + ------------------------------------- + +5. Prepare the SD boot card - with SD card reader +================================================= +To prepare bootable media you need boot binaries provided by hardkernel. +File "boot.tar.gz" (link in point 3.) contains: +- E4412_S.bl1.HardKernel.bin +- E4412_S.tzsw.signed.bin +- bl2.signed.bin +- sd_fusing.sh +- u-boot.bin + +This is all you need to boot this board. But if you want to use your custom +u-boot then you need to change u-boot.bin with your own u-boot binary* +and run the script "sd_fusing.sh" - this script is valid only for SD card. + +*note: +The proper binary file of current U-boot is u-boot-dtb.bin. + +quick steps for Linux: +- extract boot.tar.gz +- put any SD card into the SD reader +- check the device with "dmesg" +- run ./sd_fusing.sh /dev/sdX - where X is SD card device (but not a partition) +Check if Hardkernel U-boot is booting, and next do the same with your U-boot. + +6. Prepare the eMMC boot card + with a eMMC card reader (boot from eMMC card slot) +===================================================== +To boot the device from the eMMC slot you should use a special card reader +which supports eMMC partiion switch. All of the boot binaries are stored +on the eMMC boot partition which is normally hidden. + +The "sd_fusing.sh" script can be used after updating offsets of binaries +according to the table from point 4. Be sure that you are working on the right +eMMC partition - its size is usually very small, about 1-4 MiB. + +7. Prepare the eMMC boot card + with a SD card reader (boot from SD card slot) +================================================= +If you have an eMMC->microSD adapter you can prepare the card as in point 5. +But then the device can boot only from the SD card slot. + +8. Prepare the boot media using Hardkernel U-boot +================================================= +You can update the U-boot to the custom one if you have an working bootloader +delivered with the board on a eMMC/SD card. Then follow the steps: +- install the android fastboot tool +- connect a micro usb cable to the board +- on the U-boot prompt, run command: fastboot (as a root) +- on the host, run command: "fastboot flash bootloader u-boot-dtb.bin" +- the custom U-boot should start after the board resets. + +9. Partition layout +==================== +Default U-boot environment is setup for fixed partiion layout. + +Partition table: MSDOS. Disk layout and files as listed in the table below. + ----- ------ ------ ------ -------- --------------------------------- +| Num | Name | FS | Size | Offset | Reguired files | +| | | Type | MiB | MiB | | + ----- ------ ------ ------ -------- --------------------------------- +| 1 | BOOT | fat | 100 | 2 | kernel, fdt** | +| 2 | ROOT | ext4 | - | | any Linux system | + ----- ------ ------ ------ -------- --------------------------------- + +**note: +Supported fdt files are: +- exynos4412-odroidx2.dtb +- exynos4412-odroidu3.dtb + +Supported kernel files are: +- Image.itb +- zImage +- uImage + +The default environmental variable "dfu_alt_info" is set* for above layout. +Each partition size is just an example, dfu_alt_info tries init two partitions. +The size of each is not important. + +*note: +$dfu_alt_info is set on a boot time and it is concatenated using two variables: +- $dfu_alt_boot(set dynamically) +- $dfu_alt_system(from current env). + +To add any changes to dfu_alt_info - please modify $dfu_alt_system only. +Changes are visible after board reset. + +10. The environment and booting the kernel +========================================== +There are three macros defined in config for various boot options: +Two for both, kernel with device tree support and also without it: +- boot_uimg - load uImage +- boot_zimg - load zImage +If proper fdt file exists then it will be automatically loaded, +so for old kernel types, please remove fdt file from boot partition. + +The third boot option for multi image support (more info: doc/uImage.FIT/) +- boot_fit - for binary file: "Image.itb" + +Default boot command: "autoboot" +And the boot sequence is: +- boot_fit - if "Image.itb" exists +- boot_zimg - if "zImage" exists +- boot_uimg - if "uImage" exists diff --git a/include/configs/odroid.h b/include/configs/odroid.h new file mode 100644 index 0000000..29dcc4a --- /dev/null +++ b/include/configs/odroid.h @@ -0,0 +1,216 @@ +/* + * Copyright (C) 2014 Samsung Electronics + * Sanghee Kim + * Piotr Wilczek + * Przemyslaw Marczak + * + * Configuation settings for the Odroid-U3 (EXYNOS4412) board. + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +#ifndef __CONFIG_ODROID_U3_H +#define __CONFIG_ODROID_U3_H + +#include + +#define CONFIG_SYS_PROMPT "Odroid # " /* Monitor Command Prompt */ + +#undef CONFIG_DEFAULT_DEVICE_TREE +#define CONFIG_DEFAULT_DEVICE_TREE exynos4412-odroid + +#define CONFIG_SYS_L2CACHE_OFF +#ifndef CONFIG_SYS_L2CACHE_OFF +#define CONFIG_SYS_L2_PL310 +#define CONFIG_SYS_PL310_BASE 0x10502000 +#endif + +#define CONFIG_MACH_TYPE 4289 + +#define CONFIG_NR_DRAM_BANKS 8 +#define CONFIG_SYS_SDRAM_BASE 0x40000000 +#define SDRAM_BANK_SIZE (256 << 20) /* 256 MB */ +#define PHYS_SDRAM_1 CONFIG_SYS_SDRAM_BASE + +/* memtest works on */ +#define CONFIG_SYS_MEMTEST_START CONFIG_SYS_SDRAM_BASE +#define CONFIG_SYS_MEMTEST_END (CONFIG_SYS_SDRAM_BASE + 0x5E00000) +#define CONFIG_SYS_LOAD_ADDR (CONFIG_SYS_SDRAM_BASE + 0x3E00000) +#define CONFIG_SYS_TEXT_BASE 0x43e00000 + +#include +/* Size of malloc() pool */ +#define CONFIG_SYS_MALLOC_LEN (CONFIG_ENV_SIZE + (80 * SZ_1M)) + +/* select serial console configuration */ +#define CONFIG_SERIAL1 +#define CONFIG_BAUDRATE 115200 + +/* Console configuration */ +#define CONFIG_SYS_CONSOLE_INFO_QUIET +#define CONFIG_SYS_CONSOLE_IS_IN_ENV + +#define CONFIG_CMD_BOOTZ +#define CONFIG_FIT +#define CONFIG_FIT_VERBOSE +#define CONFIG_BOOTARGS "Please use defined boot" +#define CONFIG_BOOTCOMMAND "run autoboot" +#define CONFIG_DEFAULT_CONSOLE "console=ttySAC1,115200n8\0" + +#define CONFIG_SYS_INIT_SP_ADDR (CONFIG_SYS_LOAD_ADDR \ + - GENERATED_GBL_DATA_SIZE) + +#define CONFIG_SYS_MEM_TOP_HIDE (SZ_1M) /* ram console */ + +#define CONFIG_SYS_MONITOR_BASE 0x00000000 + +#define CONFIG_ENV_IS_IN_MMC +#define CONFIG_SYS_MMC_ENV_DEV CONFIG_MMC_DEFAULT_DEV +#define CONFIG_ENV_SIZE 4096 +#define CONFIG_ENV_OFFSET (SZ_1K * 1280) /* 1.25 MiB offset */ +#define CONFIG_ENV_OVERWRITE + +/* Partitions name */ +#define PARTS_BOOT "boot" +#define PARTS_ROOT "platform" + +#define CONFIG_DFU_ALT \ + "uImage fat 0 1;" \ + "zImage fat 0 1;" \ + "Image.itb fat 0 1;" \ + "uInitrd fat 0 1;" \ + "exynos4412-odroidu3.dtb fat 0 1;" \ + "exynos4412-odroidx2.dtb fat 0 1;" \ + ""PARTS_BOOT" part 0 1;" \ + ""PARTS_ROOT" part 0 2\0" \ + +#define CONFIG_SET_DFU_ALT_INFO +#define CONFIG_SET_DFU_ALT_BUF_LEN (SZ_1K) + +#define CONFIG_DFU_ALT_BOOT_EMMC \ + "u-boot raw 0x3e 0x800 mmcpart 1;" \ + "bl1 raw 0x0 0x1e mmcpart 1;" \ + "bl2 raw 0x1e 0x1d mmcpart 1;" \ + "tzsw raw 0x83e 0x138 mmcpart 1\0" + +#define CONFIG_DFU_ALT_BOOT_SD \ + "u-boot raw 0x3f 0x800;" \ + "bl1 raw 0x1 0x1e;" \ + "bl2 raw 0x1f 0x1d;" \ + "tzsw raw 0x83f 0x138\0" + +/* + * Bootable media layout: + * dev: SD eMMC(part boot) + * BL1 1 0 + * BL2 31 30 + * UBOOT 63 62 + * TZSW 2111 2110 + * ENV 2560 2560(part user) + * + * MBR Primary partiions: + * Num Name Size Offset + * 1.
