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 ${filesize} +U-Boot > +U-Boot > run upd_uboot +Using DaVinci-EMAC device +TFTP from server 192.168.1.1; our IP address is 192.168.20.71 +Filename '/tftpboot/ipam390/u-boot.ais'. +Load address: 0xc0000000 +Loading: ################################## + 1.5 MiB/s +done +Bytes transferred = 493716 (78894 hex) + +NAND erase.part: device 0 offset 0x20000, size 0x160000 +Erasing at 0x160000 -- 100% complete. +OK + +NAND write: device 0 offset 0x20000, size 0x78894 + 493716 bytes written: OK +U-Boot > + +Recovery +======== + +In the case of a "bricked" board, you need to use the TI tools found +here[1] to create an uboot-uart-ais.bin file + +- cd to the u-boot source tree + +- compile the u-boot for the ipam390 board: +$ ./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!

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.
