   2 Layerscape Quick Start
   3
   4 1. Layerscape target support
   5 ----------------------------
   6 * ARMv8 64-bit
   7   LS1012ARDB LS1012AFRWY LS1043ARDB LS1046ARDB LS1088ARDB LS2088ARDB
   8   (SD card boot support on LS1043ARDB/LS1046ARDB/LS1088ARDB)
   9
  10 * ARMv7
  11   LS1021ATWR LS1021AIOT
  12   (SD card boot support on LS1021ATWR/LS1021AIOT)
  13
  14
  15 2. Build
  16 --------
  17 Before configuration and build, update and install package feeds.
  18
  19 $ ./scripts/feeds update -a
  20 $ ./scripts/feeds install -a
  21
  22 * make menuconfig
  23   Target System:   "NXP Layerscape"
  24   Subtarget:       (Select subtarget)
  25   Target Profile:  (Select device, or "Multiple devices")
  26   Target Devices:  (Select devices. Available when Target Profile is "Multiple devices")
  27   Target Images:   (Disable "GZip images" if don't want to unzip manually to use the images.)
  28
  29   Note: The first time make menuconfig would create a .config file which
  30   would include all dependencies for selected target. After that, make
  31   menuconfig still could be used to modify packages. If want to change
  32   other target, please remove .config and make menuconfig to select again.
  33   Otherwise the packages selected in .config would be a mess.
  34
  35 * make download (or make download -j<n>)
  36
  37 * make (or make -j<n>)
  38
  39 * Final firmware/image
  40   Path: bin/targets/layerscape/<subtarget>/
  41   Firmware for flash: openwrt-layerscape-<subtarget>-<device>-<rootfs>-firmware.bin
  42   Image for SD card: openwrt-layerscape-<subtarget>-<device>-<rootfs>-sdcard.img
  43
  44
  45 3. Program NOR/QSPI flash or SD card
  46 ------------------------------------
  47 The firmware.bin or sdcard.img is an all-in-one image including all things for
  48 OpenWrt staring up. (except LS1012AFRWY. Refer to 3.3.)
  49 If you want to install all things into flash, please use firmware.bin.
  50 If you want to install all things into SD card, please use sdcard.img.
  51
  52 3.1 Program sdcard.img to SD card
  53 ---------------------------------
  54 sdcard.img could be programmed to SD card in either u-boot environment
  55 or linux environment. After programming, configure the board to boot
  56 from SD card.
  57
  58 * u-boot environment
  59
  60   => tftp a0000000 <image_name>-sdcard.img
  61   => mmc write a0000000 0 a0000
  62
  63   Note: The default sdcard.img size is 320MB. a0000 is the block number for 320MB.
  64   blk_num = filesize / 512.
  65
  66 * linux environment
  67
  68   $ dd if=./<image_name>-sdcard.img of=/dev/mmcblkx
  69
  70   Note: Need to check the SD card device name to replace "mmcblkx".
  71
  72 3.2 Program firmware.bin to flash
  73 ---------------------------------
  74 * LS1012ARDB (QSPI flash)
  75   Start up from bank1, and program firmware to bank2 with below commands.
  76   Switch to bank2 to start up OpenWrt.
  77
  78   => tftp a0000000 <firmware_name>-firmware.bin
  79   => i2c mw 0x24 0x7 0xfc;i2c mw 0x24 0x3 0xf5
  80   => sf probe 0:0
  81   => sf erase 0 +$filesize
  82   => sf write a0000000 0 $filesize
  83   => reset
  84
  85 * LS1043ARDB (NOR flash)
  86   Start up from bank0, and program firmware to bank4 with below commands.
  87   Switch to bank4 to start up OpenWrt.
  88
  89   => tftp a0000000 <firmware_name>-firmware.bin
  90   => protect off all
  91   => erase 64000000 +$filesize
  92   => cp.b a0000000 64000000 $filesize
  93   => cpld reset altbank
  94
  95 * LS1046ARDB (QSPI flash)
  96   Start up from bank1, and program firmware to bank2 with below commands.
  97   Switch to bank2 to start up OpenWrt.
  98
  99   => tftp a0000000 <firmware_name>-firmware.bin
 100   => sf probe 0:1
 101   => sf erase 0 +$filesize
 102   => sf write a0000000 0 $filesize
 103   => cpld reset altbank
 104
 105 * LS1088ARDB (QSPI flash)
 106   Start up from bank0, and program firmware to bank1 with below commands.
 107   Switch to bank1 to start up OpenWrt.
 108
 109   => tftp a0000000 <firmware_name>-firmware.bin
 110   => sf probe 0:1
 111   => sf erase 0 +$filesize
 112   => sf write a0000000 0 $filesize
 113   => qix altbank
 114
 115   Note: old version u-boot of ls1088ardb may use below commands to switch to
 116   bank1 instead of 'qix altbank'.
 117   => i2c mw 66 50 20;i2c mw 66 10 20;i2c mw 66 10 21
 118
 119 * LS2088ARDB (NOR flash)
 120   Start up from bank0, and program firmware to bank4 with below commands.
 121   Switch to bank4 to start up OpenWrt.
 122
 123   => tftp a0000000 <firmware_name>-firmware.bin
 124   => protect off all
 125   => erase 584000000 +$filesize
 126   => cp.b a0000000 584000000 $filesize
 127   => qix altbank
 128
 129 3.3 Program LS1012AFRWY
 130 -----------------------
 131 * LS1012AFRWY (QSPI flash + SD card)
 132   LS1012AFRWY only supports 2MB QSPI flash. We have to put u-boot, and
 133   some firmwares on QSPI flash, and kernel/dtb/rootfs on SD card.
 134   So both firmware.bin and sdcard.img are needed for OpenWrt starting up.
 135
 136   To program sdcard.img, please use linux command described in 3.1 on a
 137   linux machine.
 138   To program firmware.bin, start up board from QSPI flash, and program
 139   firmware with below commands. Reset to start up OpenWrt. (LS1012AFRWY
 140   supports only one bank.)
 141
 142   => tftp 96000000 <firmware_name>-firmware.bin
 143   => sf probe 0:0
 144   => sf erase 0 +$filesize
 145   => sf write 96000000 0 $filesize
 146   => reset
 147
 148
 149 4. Known issues and limitation
 150 ------------------------------
 151 * u-boot may fail to read MAC addresses from EEPROM on some boards and there
 152   won't be MAC addresses set in environment. This may cause kernel fails to
 153   probe these network interfaces. The workaround is to set MAC addresses
 154   manually, for example,
 155
 156   => setenv ethaddr 00:04:9F:04:65:4b
 157   => setenv eth1addr 00:04:9F:04:65:4c
