Boot source: +--------------- + +The Gateworks Ventana boards support booting from NAND or micro-SD depending +on the board model. The IMX6 BOOT ROM will choose a boot media based on eFUSE +settings programmed at the factory. + +Boards with NAND flash will always boot from NAND, and NAND-less boards will +always boot from micro-SD. However, it is possible to use the U-Boot bmode +command (or the technique it uses) to essentially bootstrap to another boot +media at runtime. + +3.1. boot from NAND +------------------- + +The i.MX6 BOOT ROM expects some structures that provide details of NAND layout +and bad block information (referred to as 'bootstreams') which are replicated +multiple times in NAND. The number of replications and their spacing (referred +to as search stride) is configurable through board strapping options and/or +eFUSE settings (BOOT_SEARCH_COUNT / Pages in block from BOOT_CFG2). In +addition, the i.MX6 BOOT ROM Flash Configuration Block (FCB) supports two +copies of a bootloader in flash in the case that a bad block has corrupted one. +The Freescale 'kobs-ng' application from the Freescale LTIB BSP, which runs +under Linux and operates on an MTD partition, must be used to program the +bootstream in order to setup this flash structure correctly. + +The Gateworks Ventana boards with NAND flash have been factory programmed +such that their eFUSE settings expect 2 copies of the boostream (this is +specified by providing kobs-ng with the --search_exponent=1 argument). Once in +Linux with MTD support for the NAND on /dev/mtd0 you can program the SPL +with: + +kobs-ng init -v -x --search_exponent=1 SPL + +The kobs-ng application uses an imximage which contains the Image Vector Table +(IVT) and Device Configuration Data (DCD) structures that the i.MX6 BOOT ROM +requires to boot. The kobs-ng adds the Firmware Configuration Block (FCB) and +Discovered Bad Block Table (DBBT). The SPL build artifact from U-Boot is +an imximage. + +The u-boot.img, which is the non SPL U-Boot binary appended to a U-Boot image +header must be programmed in the NAND flash boot device at an offset hard +coded in the SPL. For the Ventana boards, this has been chosen to be 14MB. +The image can be programmed from either U-Boot or Linux: + +U-Boot: +Ventana > setenv mtdparts mtdparts=nand:14m(spl),2m(uboot),1m(env),-(rootfs) +Ventana > tftp ${loadaddr} u-boot.img && nand erase.part uboot && \ + nand write ${loadaddr} uboot ${filesize} + +Linux: +nandwrite /dev/mtd1 u-boot.img + +The above assumes the default Ventana partitioning scheme which is configured +via the mtdparts env var: + - spl: 14MB + - uboot: 2M + - env: 1M + - rootfs: the rest + +This information is taken from: + http://trac.gateworks.com/wiki/ventana/bootloader#nand + +More details about the i.MX6 BOOT ROM can be found in the IMX6 reference manual. + +3.1. boot from MMC (eMMC/microSD) +--------------------------------- + +When the IMX6 eFUSE settings have been factory programmed to boot from +MMC the SPL will be loaded from offset 0x400 (1KB). Once the SPL is +booted, it will load and execute U-Boot (u-boot.img) from offset 69KB +on the micro-SD (defined by CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR). + +While it is technically possible to enable the SPL to be able to load +U-Boot from a file on a FAT/EXT filesystem on the micro-SD, we chose to +use raw micro-SD access to keep the code-size and boot time of the SPL down. + +For these reasons an MMC device that will be used as an IMX6 primary boot +device must be carefully partitioned and prepared. + +The following shell commands are executed on a Linux host (adjust DEV to the +block storage device of your MMC, ie /dev/mmcblk0): + + DEV=/dev/sdc + # zero out 1MB of device + sudo dd if=/dev/zero of=$DEV count=1 bs=1M oflag=sync status=none && sync + # copy SPL to 1KB offset + sudo dd if=SPL of=$DEV bs=1K seek=1 oflag=sync status=none && sync + # copy U-Boot to 69KB offset + sudo dd if=u-boot.img of=$DEV bs=1K seek=69 oflag=sync status=none && sync + # create a partition table with a single rootfs partition starting at 1MB + printf "1,,L\n" | sudo sfdisk --in-order --no-reread -L -uM $DEV && sync + # format partition + sudo mkfs.ext4 -L root ${DEV}1 + # mount the partition + sudo udisks --mount ${DEV}1 + # extract filesystem + sudo tar xvf rootfs.tar.gz -C /media/root + # flush and unmount + sync && sudo umount /media/root + +The above assumes the default Ventana micro-SD partitioning scheme + - spl : 1KB-69KB (68KB) required by IMX6 BOOT ROM + - uboot : 69KB-709KB (640KB) defined by + CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR + - env : 709KB-965KB (256KB) defined by + CONFIG_ENV_MMC_SIZE + CONFIG_ENV_MMC_OFFSET_REDUND + - rootfs : 1MB- + +This information is taken from: + http://trac.gateworks.com/wiki/ventana/bootloader#microsd + +More details about the i.MX6 BOOT ROM can be found in the IMX6 reference manual. + +4. Falcon Mode +------------------------------ + +The Gateworks Ventana board config enables Falcon mode (CONFIG_SPL_OS_BOOT) +which allows the SPL to boot directly to an OS instead of to U-Boot +(u-boot.img) thus acheiving a faster overall boot time. The time savings +depends on your boot medium (ie NAND Flash vs micro-SD) and size/storage +of the OS. The time savings can be anywhere from 2 seconds (256MB NAND Flash +with ~1MB kernel) to 6 seconds or more (2GB NAND Flash with ~6 kernel) + +The Gateworks Ventana board supports Falcon mode for the following boot +medium: + - NAND flash + - micro-SD + +For all boot mediums, raw mode is used. While support of more complex storage +such as files on top of FAT/EXT filesystem is possible but not practical +as the size of the SPL is fairly limitted (to 64KB based on the smallest +size of available IMX6 iRAM) as well as the fact that this would increase +OS load time which defeats the purpose of Falcon mode in the first place. + +The SPL decides to boot either U-Boot (u-boot.img) or the OS (args + kernel) +based on the return value of the spl_start_uboot() function. While often +this can simply be the state of a GPIO based pushbutton or DIP switch, for +Gateworks Ventana, we use an EEPROM register on i2c-0 at 0x50:0x00: +set to '0' will choose to boot to U-Boot and otherwise it will boot to OS. + +To use Falcon mode it is required that you first 'prepare' the 'args' data +that is stored on your boot medium along with the kernel (which can be any +OS or bare-metal application). In the case of the Linux kernel the 'args' +is the flatenned device-tree which normally gets altered prior to booting linux +by U-Boot's 'bootm' command. To achieve this for SPL we use the +'spl export fdt' command in U-Boot after loading the kernel and dtb which +will go through the same process of modifying the device-tree for the board +being executed on but not jump to the kernel. This allows you to save the +args data to the location the SPL expects it and then enable Falcon mode. + +It is important to realize that there are certain values in the dtb that +are board model specific (IMX6Q vs IMX6DL for example) and board specific +(board serial number, MAC addrs) so you do not want to use the 'args' +data prepared from one board on another board. + +4.1. Falcon Mode on NAND flash +------------------------------ +To prepare a Gateworks Ventana board that boots from NAND flash for Falcon +mode you must program your flash such that the 'args' and 'kernel' are +located where defined at compile time by the following: + CONFIG_CMD_SPL_NAND_OFS 17MB - offset of 'args' + CONFIG_SYS_NAND_SPL_KERNEL_OFFS 18MB - offset of 'kernel' + +The location offsets defined above are defaults chosen by Gateworks and are +flexible if you want to re-define them. + +The following steps executed in U-Boot will configure Falcon mode for NAND +using rootfs (ubi), kernel (uImage), and dtb from the network: + + # change mtd partitions to the above mapping + Ventana > setenv mtdparts 'mtdparts=nand:14m(spl),2m(uboot),1m(env),1m(args),10m(kernel),-(rootfs)' + + # flash rootfs (at 28MB) + Ventana > tftp ${loadaddr} rootfs_${flash_layout}.ubi && \ + nand erase.part rootfs && nand write ${loadaddr} rootfs ${filesize} + + # load the device-tree + Ventana > tftp ${fdt_addr} ventana/${fdt_file2} + + # load the kernel + Ventana > tftp ${loadaddr} ventana/uImage + + # flash kernel (at 18MB) + Ventana > nand erase.part kernel && nand write ${loadaddr} kernel ${filesize} + + # set kernel args for the console and rootfs (used by spl export) + Ventana > setenv bootargs 'console=ttymxc1,115200 root=ubi0:rootfs ubi.mtd=5 rootfstype=ubifs quiet' + + # create args based on env, board, EEPROM, and dtb + Ventana > spl export fdt ${loadaddr} - ${fdt_addr} + + # flash args (at 17MB) + Ventana > nand erase.part args && nand write 18000000 args 100000 + + # set i2c register 0x50:0x00=0 to boot to Linux + Ventana > i2c dev 0 && i2c mw 0x50 0x00.0 0 1 + +Be sure to adjust 'bootargs' above to your OS needs (this will be different +for various distros such as OpenWrt, Yocto, Android, etc).

Falcon Mode on micro-SD card +--------------------------------- + +To prepare a Gateworks Ventana board with a primary boot device of micro-SD +you first need to make sure you build U-Boot with CONFIG_ENV_IS_IN_MMC +instead of CONFIG_ENV_IS_IN_NAND. + +For micro-SD based Falcon mode you must program your micro-SD such that +the 'args' and 'kernel' are located where defined at compile time +by the following: + CONFIG_SYS_MMCSD_RAW_MODE_ARGS_SECTOR 0x800 (1MB) - offset of 'args' + CONFIG_SYS_MMCSD_RAW_MODE_KERNEL_SECTOR 0x1000 (2MB) - offset of 'kernel' + +The location offsets defined above are defaults chosen by Gateworks and are +flexible if you want to re-define them. + +First you must prepare a micro-SD such that the SPL can be loaded by the +IMX6 BOOT ROM (fixed offset of 1KB), and U-Boot can be loaded by the SPL +(fixed offset of 69KB defined by CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR). + +The following shell commands are executed on a Linux host (adjust DEV to the +block storage device of your micro-SD): + + DEV=/dev/sdc + # zero out 1MB of device + sudo dd if=/dev/zero of=$DEV count=1 bs=1M oflag=sync status=none && sync + # copy SPL to 1KB offset + sudo dd if=SPL of=$DEV bs=1K seek=1 oflag=sync status=none && sync + # copy U-Boot to 69KB offset + sudo dd if=u-boot.img of=$DEV bs=1K seek=69 oflag=sync status=none && sync + # create a partition table with a single rootfs partition starting at 10MB + printf "10,,L\n" | sudo sfdisk --in-order --no-reread -L -uM $DEV && sync + # format partition + sudo mkfs.ext4 -L root ${DEV}1 + # mount the partition + sudo udisks --mount ${DEV}1 + # extract filesystem + sudo tar xvf rootfs.tar.gz -C /media/root + # flush and unmount + sync && sudo umount /media/root + +Now that your micro-SD partitioning has been adjusted to leave room for the +raw 'args' and 'kernel' data boot the board with the prepared micro-SD, break +out in U-Boot and use the following to enable Falcon mode: + + # load device-tree from rootfs + Ventana > ext2load mmc 0:1 ${fdt_addr} boot/${fdt_file2} + + # load kernel from rootfs + Ventana > ext2load mmc 0:1 ${loadaddr} boot/uImage + + # write kernel at 2MB offset + Ventana > mmc write ${loadaddr} 0x1000 0x4000 + + # setup kernel bootargs + Ventana > setenv bootargs 'console=ttymxc1,115200 root=/dev/mmcblk0p1 rootfstype=ext4 rootwait rw' + + # prepare args + Ventana > spl export fdt ${loadaddr} - ${fdt_addr} + + # write args 1MB data (0x800 sectors) to 1MB offset (0x800 sectors) + Ventana > mmc write 18000000 0x800 0x800 + + # set i2c register 0x50:0x00=0 to boot to Linux + Ventana > i2c dev 0 && i2c mw 0x50 0x00.0 0 1 + +Be sure to adjust 'bootargs' above to your OS needs (this will be different +for various distros such as OpenWrt, Yocto, Android, etc).
