Note: There is also a sha1sum command, which should perhaps
be deprecated in favour of 'hash sha1'.
- Freescale i.MX specific commands:
CONFIG_CMD_HDMIDETECT
This enables 'hdmidet' command which returns true if an
HDMI monitor is detected. This command is i.MX 6 specific.
CONFIG_CMD_BMODE
This enables the 'bmode' (bootmode) command for forcing
a boot from specific media.
This is useful for forcing the ROM's usb downloader to
activate upon a watchdog reset which is nice when iterating
on U-Boot. Using the reset button or running bmode normal
will set it back to normal. This command currently
supports i.MX53 and i.MX6.
- Signing support:
CONFIG_RSA

Summary
=======
The README is for the boot procedure on the ipam390 board
In the context of U-Boot, the board is booted in three stages. The initial
bootloader which executes upon reset is the ROM Boot Loader (RBL) and sits
in the internal ROM. The RBL initializes the internal memory and then
depending on the exact board and pin configurations will initialize another
controller (such as NAND) to continue the boot process by loading
the secondary program loader (SPL). The SPL will initialize the system
further (some clocks, SDRAM). As on this board is used the falcon boot
mode, now 2 ways are possible depending on the GPIO 7_14 input pin,
connected with the "soft reset switch"
If this pin is logical 1 (high level):
spl code starts the kernel image without delay
If this pin is logical 0 (low level):
spl code starts the u-boot image
AIS is an image format defined by TI for the images that are to be loaded
to memory by the RBL. The image is divided into a series of sections and
the image's entry point is specified. Each section comes with meta data
like the target address the section is to be copied to and the size of the
section, which is used by the RBL to load the image. At the end of the
image the RBL jumps to the image entry point. The AIS format allows for
other things such as programming the clocks and SDRAM if the header is
programmed for it. We do not take advantage of this and instead use SPL as
it allows for additional flexibility (run-time detect of board revision,
loading the next image from a different media, etc).
Compilation
===========
run "./MAKEALL ipam390" in the u-boot source tree.
Once this build completes you will have a u-boot.ais file that needs to
be written to the nand flash.
Flashing the images to NAND
==========================
The AIS image can be written to NAND flash using the following commands.
Assuming that the network is configured and enabled and the u-boot.ais file
is tftp'able.
U-Boot > print upd_uboot
upd_uboot=tftp c0000000 ${u-boot};nand erase.part u-boot;nand write c0000000 20000 ${filesize}

Recovery
========
In the case of a "bricked" board, you need to use the TI tools found
here[1] to create an uboot-uart-ais.bin file
- cd to the u-boot source tree
- compile the u-boot for the ipam390 board:
$ ./MAKEALL ipam390
-> Now we shall have u-boot.bin
- Create u-boot-uart-ais.bin
$ mono HexAIS_OMAP-L138.exe -entrypoint 0xC1080000 -ini
ipam390-ais-uart.cfg -o ./uboot-uart-ais.bin ./u-boot.bin@0xC1080000;
Note: The ipam390-ais-uart.cfg is found in the board directory
for the ipam390 board, u-boot:/board/Barix/ipam390/ipam390-ais-uart.cfg
- We can now run bootloader on IPAM390 via UART using the command below:
$ mono ./slh_OMAP-L138.exe -waitForDevice -v -p /dev/tty.UC-232AC uboot-uart-ais.bin
NOTE: Do not cancel the command execution! The command takes 20+ seconds
to upload u-boot over serial and run it!
Outcome:

Falcon Bootmode (boot linux without booting U-Boot)
===================================================
The Falcon Mode extends this way allowing to start the Linux kernel directly
from SPL. A new command is added to U-Boot to prepare the parameters that SPL
must pass to the kernel, using ATAGS or Device Tree.
In normal mode, these parameters are generated each time before
loading the kernel, passing to Linux the address in memory where
the parameters can be read.
With Falcon Mode, this snapshot can be saved into persistent storage and SPL is
informed to load it before running the kernel.
To boot the kernel, these steps under a Falcon-aware U-Boot are required:
1. Boot the board into U-Boot.
Use the "spl export" command to generate the kernel parameters area or the DT.
U-Boot runs as when it boots the kernel, but stops before passing the control
to the kernel.
Here the command sequence for the ipam390 board:
- load the linux kernel image into ram:
U-Boot > nand read c0100000 2 200000 400000
NAND read: device 0 offset 0x200000, size 0x400000
4194304 bytes read: OK

Summary
=======
This document covers various features of the 'am335x_evm' build, and some of
the related build targets (am335x_evm_uartN, etc).
Hardware
========
The binary produced by this board supports, based on parsing of the EEPROM
documented in TI's reference designs:
- AM335x GP EVM
- AM335x EVM SK
- Beaglebone White
- Beaglebone Black
'
NAND
====
The AM335x GP EVM ships with a 256MiB NAND available in most profiles. In
this example to program the NAND we assume that an SD card has been
inserted with the files to write in the first SD slot and that mtdparts
have been configured correctly for the board. As a time saving measure we
load MLO into memory in one location, copy it into the three locatations
that the ROM checks for additional valid copies, then load U-Boot into
memory. We then write that whole section of memory to NAND.
U-Boot # mmc rescan
U-Boot # env default -f -a
U-Boot # nand erase.chip
U-Boot # saveenv
U-Boot # load mmc 0 81000000 MLO
U-Boot # cp.b 81000000 81020000 20000
U-Boot # cp.b 81000000 81040000 20000
U-Boot # cp.b 81000000 81060000 20000
U-Boot # load mmc 0 81080000 u-boot.img
U-Boot # nand write 81000000 0 260000
U-Boot # load mmc 0 ${loadaddr} uImage
U-Boot # nand write ${loadaddr} kernel 500000
NOR
===
The Beaglebone White can be equiped with a "memory cape" that in turn can
have a NOR module plugged into it. In this case it is then possible to
program and boot from NOR. Note that due to how U-Boot is architectured we
must build a specific version of U-Boot that knows we have NOR flash. This
build is named 'am335x_evm_nor'. Further, we have a 'am335x_evm_norboot'
build that will assume that the environment is on NOR rather than NAND. In
the following example we assume that and SD card has been populated with
MLO and u-boot.img from a 'am335x_evm_nor' build and also contains the
'u-boot.bin' from a 'am335x_evm_norboot' build. When booting from NOR, a
binary must be written to the start of NOR, with no header or similar
prepended. In the following example we use a size of 512KiB (0x80000)
as that is how much space we set aside before the environment, as per
the config file.
U-Boot # mmc rescan
U-Boot # load mmc 0 ${loadaddr} u-boot.bin
U-Boot # protect off 08000000 +80000
U-Boot # erase 08000000 +80000
U-Boot # cp.b ${loadaddr} 08000000 ${filesize}
Falcon Mode
===========
The default build includes "Falcon Mode" (see doc/README.falcon) via NAND,
eMMC (or raw SD cards) and FAT SD cards. Our default behavior currently is
to read a 'c' on the console while in SPL at any point prior to loading the
OS payload (so as soon as possible) to opt to booting full U-Boot. Also
note that while one can program Falcon Mode "in place" great care needs to
be taken by the user to not 'brick' their setup. As these are all eval
boards with multiple boot methods, recovery should not be an issue in this
worst-case however.
Falcon Mode: eMMC
=================
The recommended layout in this case is:
MMC BLOCKS |--------------------------------| LOCATION IN BYTES
0x0000 - 0x007F : MBR or GPT table : 0x000000 - 0x020000
0x0080 - 0x00FF : ARGS or FDT file : 0x010000 - 0x020000
0x0100 - 0x01FF : SPL.backup1 (first copy used) : 0x020000 - 0x040000
0x0200 - 0x02FF : SPL.backup2 (second copy used) : 0x040000 - 0x060000
0x0300 - 0x06FF : U-Boot : 0x060000 - 0x0e0000
0x0700 - 0x08FF : U-Boot Env + Redundant : 0x0e0000 - 0x120000
0x0900 - 0x28FF : Kernel : 0x120000 - 0x520000
Note that when we run 'spl export' it will prepare to boot the kernel.
This includes relocation of the uImage from where we loaded it to the entry
point defined in the header. As these locations overlap by default, it
would leave us with an image that if written to MMC will not boot, so
instead of using the loadaddr variable we use 0x81000000 in the following
example. In this example we are loading from the network, for simplicity,
and assume a valid partition table already exists and 'mmc dev' has already
been run to select the correct device. Also note that if you previously
had a FAT partition (such as on a Beaglebone Black) it is not enough to
write garbage into the area, you must delete it from the partition table
first.
# Ensure we are able to talk with this mmc device
U-Boot # mmc rescan
U-Boot # tftp 81000000 am335x/MLO
# Write to two of the backup locations ROM uses
U-Boot # mmc write 81000000 100 100
U-Boot # mmc write 81000000 200 100
# Write U-Boot to the location set in the config
U-Boot # tftp 81000000 am335x/u-boot.img
U-Boot # mmc write 81000000 300 400
# Load kernel and device tree into memory, perform export
U-Boot # tftp 81000000 am335x/uImage
U-Boot # run findfdt
U-Boot # tftp ${fdtaddr} am335x/${fdtfile}
U-Boot # run mmcargs
U-Boot # spl export fdt 81000000 - ${fdtaddr}
# Write the updated device tree to MMC
U-Boot # mmc write ${fdtaddr} 80 80
# Write the uImage to MMC
U-Boot # mmc write 81000000 900 2000
Falcon Mode: FAT SD cards
=========================
In this case the additional file is written to the filesystem. In this
example we assume that the uImage and device tree to be used are already on
the FAT filesystem (only the uImage MUST be for this to function
afterwards) along with a Falcon Mode aware MLO and the FAT partition has
already been created and marked bootable:
U-Boot # mmc rescan
# Load kernel and device tree into memory, perform export
U-Boot # load mmc 0:1 ${loadaddr} uImage
U-Boot # run findfdt
U-Boot # load mmc 0:1 ${fdtaddr} ${fdtfile}
U-Boot # run mmcargs
U-Boot # spl export fdt ${loadaddr} - ${fdtaddr}
This will print a number of lines and then end with something like:
Using Device Tree in place at 80f80000, end 80f85928
Using Device Tree in place at 80f80000, end 80f88928
So then you:
U-Boot # fatwrite mmc 0:1 0x80f80000 args 8928
Falcon Mode: NAND
=================
In this case the additional data is written to another partition of the
NAND. In this example we assume that the uImage and device tree to be are
already located on the NAND somewhere (such as fileystem or mtd partition)
along with a Falcon Mode aware MLO written to the correct locations for
booting and mtdparts have been configured correctly for the board:
U-Boot # nand read ${loadaddr} kernel
U-Boot # load nand rootfs ${fdtaddr} /boot/am335x-evm.dtb
U-Boot # run nandargs
U-Boot # spl export fdt ${loadaddr} - ${fdtaddr}
U-Boot # nand erase.part u-boot-spl-os
U-Boot # nand write ${fdtaddr} u-boot-spl-os
