History

Yangbo Lu 7016dd48f1 layerscape: add ls1012afrwy support and drop ls1012afrdm ls1012afrdm was no longer supported in NXP Layerscape SDK. Instead a new board ls1012afrwy was introduced in LSDK. This patch is to drop ls1012afrdm and add ls1012afrwy support. Since only 2MB NOR flash could be used, we just put u-boot and firmware on NOR flash, and put kernel/dtb/rootfs on SD card. The Layerscape FRWY-LS1012A board is an ultra-low-cost development platform for LS1012A Series Communication Processors built on Arm Cortex-A53. This tool refines the FRDM-LS1012A with more features for a better hands-on experience for IoT, edge computing, and various advanced embedded applications. Features include easy access to processor I/O, low-power operation, micro SD card storage, an M2 connector, a small form factor, and expansion board options via mikroBUS Click Module. The MicroBUS Module provides easy expansion via hundreds of powerful modules supporting sensors, actuators, memories, and displays. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>		6 years ago

Layerscape Quick Start

1. Layerscape target support
----------------------------
* ARMv8 64-bit
  LS1012ARDB LS1012AFRDM LS1043ARDB LS1046ARDB LS1088ARDB LS2088ARDB

* ARMv8 32-bit
  LS1012ARDB LS1012AFRDM LS1043ARDB LS1046ARDB


2. Build
--------
Before configuration and build, update and install package feeds.

$ ./scripts/feeds update -a
$ ./scripts/feeds install -a

2.1 make menuconfig
-------------------
* For single device

  Target System:   "NXP Layerscape".
  Subtarget:       "ARMv8 64-bit based boards" or "ARMv8 32-bit based boards"
  Target Profile:  (select device you want to build)

  For example, build firmware for 64-bit ls1043ardb.
  +---------------------------------------------+
  | Target System (NXP Layerscape)  --->        |
  |---------------------------------------------|
  | Subtarget (ARMv8 64-bit based boards)  ---> |
  |---------------------------------------------|
  | Target Profile (ls1043ardb-armv8_64b)  ---> |
  +---------------------------------------------+

* For multiple devices

  Target System:   "NXP Layerscape".
  Subtarget:       "ARMv8 64-bit based boards" or "ARMv8 32-bit based boards"
  Target Profile:  "Multiple devices"
  Target Devices:  (select devices you want to build)

  For example, build firmware for all 64-bit devices.
  Target Devices  --->
  +-----------------------------------------------------------------+
  | [*] Enable all profiles by default                              |
  |-----------------------------------------------------------------|
  | [*] Use a per-device root filesystem that adds profile packages |
  |-----------------------------------------------------------------|
  | [*] ls1012afrdm-armv8_64b  --->                                 |
  |-----------------------------------------------------------------|
  | [*] ls1012ardb-armv8_64b  --->                                  |
  |-----------------------------------------------------------------|
  | [*] ls1043ardb-armv8_64b  --->                                  |
  |-----------------------------------------------------------------|
  | [*] ls1046ardb-armv8_64b  --->                                  |
  |-----------------------------------------------------------------|
  | [*] ls1088ardb-armv8_64b  --->                                  |
  |-----------------------------------------------------------------|
  | [*] ls2088ardb-armv8_64b  --->                                  |
  +-----------------------------------------------------------------+

Note: The first time make menuconfig would create a .config file which
would include all dependencies for selected target. After that, make
menuconfig still could be used to modify packages. If want to change
other target, please remove .config and make menuconfig to select again.
Otherwise the packages selected in .config would be a mess.

2.2 make (or make -j<n>)
------------------------

2.3 Final firmware
------------------
Final firmware would be in bin/targets/layerscape/<subtarget>/, and
named as openwrt-layerscape-<subtarget>-<device>-<rootfs>-firmware.bin.


3. Program firmware to NOR/QSPI flash
-------------------------------------
* LS1043ARDB (NOR flash)

  Start up from bank0, and program firmware to bank4 with below commands.
  Switch to bank4 to start up OpenWrt.

  => tftp a0000000 <firmware_name>.bin
  => protect off all
  => erase 64000000 +$filesize
  => cp.b a0000000 64000000 $filesize
  => cpld reset altbank

* LS2088ARDB (NOR flash)

  Start up from bank0, and program firmware to bank4 with below commands.
  Switch to bank4 to start up OpenWrt.

  => tftp a0000000 <firmware_name>.bin
  => protect off all
  => erase 584000000 +$filesize
  => cp.b a0000000 584000000 $filesize
  => qix altbank

* LS1012ARDB (QSPI flash)

  Start up from bank1, and program firmware to bank2 with below commands.
  Switch to bank2 to start up OpenWrt.

  => tftp a0000000 <firmware_name>.bin
  => i2c mw 0x24 0x7 0xfc;i2c mw 0x24 0x3 0xf5
  => sf probe 0:0
  => sf erase 0 +$filesize
  => sf write a0000000 0 $filesize
  => reset

* LS1012AFRDM (QSPI flash)

  LS1012AFRDM board only has one bank. Start up board, and program firmware
  with below commands. Reset to start up OpenWrt.

  => tftp 96000000 <firmware_name>.bin
  => sf probe 0:0
  => sf erase 0 +$filesize
  => sf write 96000000 0 $filesize
  => reset

* LS1046ARDB (QSPI flash)

  Start up from bank1, and program firmware to bank2 with below commands.
  Switch to bank2 to start up OpenWrt.

  => tftp a0000000 <firmware_name>.bin
  => sf probe 0:1
  => sf erase 0 +$filesize
  => sf write a0000000 0 $filesize
  => cpld reset altbank

* LS1088ARDB (QSPI flash)

  Start up from bank0, and program firmware to bank1 with below commands.
  Switch to bank1 to start up OpenWrt.

  => tftp a0000000 <firmware_name>.bin
  => sf probe 0:1
  => sf erase 0 +$filesize
  => sf write a0000000 0 $filesize
  => qix altbank

  Note: old version u-boot of ls1088ardb may use below commands to switch to
  bank1 instead of 'qix altbank'.
  => i2c mw 66 50 20;i2c mw 66 10 20;i2c mw 66 10 21


4. Known issues and limitation
------------------------------
* u-boot may fail to read MAC addresses from EEPROM on some boards and there
  won't be MAC addresses set in environment. This may cause kernel fails to
  probe these network interfaces. The workaround is to set MAC addresses
  manually, for example,

  => setenv ethaddr 00:04:9F:04:65:4b
  => setenv eth1addr 00:04:9F:04:65:4c
