1U-Boot for the Boundary Devices Nitrogen6X and 2Freescale i.MX6Q SabreLite boards 3 4This file contains information for the port of 5U-Boot to the Boundary Devices Nitrogen6X and 6Freescale i.MX6Q SabreLite boards. 7 81. Boot source, boot from SPI NOR 9--------------------------------- 10The configuration in this directory supports both the 11Nitrogen6X and Freescale SabreLite board, but in a 12different fashion from Freescale's implementation in 13board/freescale/mx6qsabrelite. 14 15In particular, this image supports booting from SPI NOR 16and saving the environment to SPI NOR. 17 18It does not support 'boot from SD' at offset 0x400 19except through the 'bmode' command. 20 http://lists.denx.de/pipermail/u-boot/2012-August/131151.html 21 222. Boots using 6x_bootscript on SATA or SD card 23----------------------------------------------- 24The default bootcmd for these boards is configured 25to look for and source a boot script named '6x_bootscript' 26in the root of the first partition of the following 27devices: 28 29 sata 0 30 mmc 0 31 mmc 1 32 33They're searched in the order listed above, trying both the 34ext2 and fat filesystems. 35 362. Maintaining the SPI NOR 37-------------------------- 38A couple of convenience commands 39 40 clearenv - clear environment to factory default 41 upgradeu - look and source a boot script named 42 '6x_upgrade' to upgrade the U-Boot version 43 in SPI NOR. The search is the same as for 44 6x_bootscript described above. 45 463. Display support 47------------------ 48U-Boot support for the following displays is configured by 49default: 50 51 HDMI - 1024 x 768 for maximum compatibility 52 Hannstar-XGA - 1024 x 768 LVDS (Freescale part number MCIMX-LVDS1) 53 wsvga-lvds - 1024 x 600 LVDS (Boundary p/n Nit6X_1024x600) 54 wvga-rgb - 800 x 480 RGB (Boundary p/n Nit6X_800x480) 55 56Since the ipuv3_fb display driver currently supports only a single display, 57this code auto-detects panel by probing the HDMI Phy for Hot Plug Detect 58or the I2C touch controller of the LVDS and RGB displays in the priority 59listed above. 60 61Setting 'panel' environment variable to one of the names above will 62override auto-detection and force activation of the specified panel. 63 644. Building 65------------ 66 67To build U-Boot for one of the Nitrogen6x or SabreLite board: 68 69 make nitrogen6x_config 70 make 71 72Note that 'nitrogen6x' is a placeholder. The complete list of supported 73board configurations is shown in the boards.cfg file: 74 nitrogen6q i.MX6Q/6D 1GB 75 nitrogen6dl i.MX6DL 1GB 76 nitrogen6s i.MX6S 512MB 77 nitrogen6q2g i.MX6Q/6D 2GB 78 nitrogen6dl2g i.MX6DL 2GB 79 nitrogen6s1g i.MX6S 1GB 80 81The -6q variants support either the i.MX6Quad or i.MX6Dual processors 82and are configured for a 64-bit memory bus at 1066 MHz. 83 84The -6dl variants also use a 64-bit memory bus, operated at 800MHz. 85 86The -6s variants use a 32-bit memory bus at 800MHz. 87 88If you place the u-boot.imx into a single-partition SD card 89along with a binary version of the boot script 6x_upgrade.txt, 90you can program it using 'upgradeu': 91 92 U-Boot> run upgradeu 93

1U-Boot for the Freescale i.MX6q SabreLite board 2=============================================== 3 4This file contains information for the port of U-Boot to the Freescale 5i.MX6q SabreLite board. 6 7 81. Build 9-------- 10 11To build U-Boot for the SabreLite board: 12 13 make mx6qsabrelite_config 14 make 15 16 172. Boot from SD card 18-------------------- 19 20The SabreLite boards boot from the SPI NOR flash. These boards need their SPI 21to be reflashed with a small SD card loader to support boot from SD card. The 22board will still boot from SPI NOR, but the loader will in turn request the 23BootROM to load the U-Boot from SD card. 24 25The SD card loader is available from 26 27https://wiki.linaro.org/Boards/MX6QSabreLite 28 29This is provided under a open-source 3-clause BSD license. 30 31To following procedure can be used to update the SPI-NOR on the SabreLite 32board: 33 341. Write this SD card loader onto a large SD card using: 35 36 sudo dd if=iMX6DQ_SPI_to_uSDHC3.bin of=/dev/sXx 37 38 Note: Replace sXx with the device representing the SD card in your system. 39 40 Note: This writes SD card loader at address 0 41 422. Put this SD card into the slot for the large SD card (SD3 on the bottom of 43 the board). Make sure SW1 switch is at position "00", so that it can boot 44 from the fuses. 45 463. Power-up the SabreLite, press 'space' to enter command mode in the U-Boot 47 (the default one the board is shipped with, starting from the SPI NOR) and 48 enter the following commands: 49 50 MX6Q SABRELITE U-Boot > mmc dev 0 51 MX6Q SABRELITE U-Boot > mmc read 0x10800000 0 200 52 MX6Q SABRELITE U-Boot > sf probe 53 MX6Q SABRELITE U-Boot > sf erase 0 0x40000 54 MX6Q SABRELITE U-Boot > sf write 0x10800000 0 0x40000 55 564. Write the u-boot.imx produced during the U-Boot build to the SD card: 57 58 sudo dd if=u-boot.imx of=/dev/sXx bs=512 seek=2 && sudo sync 59 60 Note: Replace sXx with the device representing the SD card in your system. 61 625. Re-insert the SD card back in the slot for the large SD card and power-cycle 63 the board. 64 65Note: The board now boots from full size SD3 on the bottom of the board. NOT 66 the micro SD4/BOOT slot on the top of the board. I.e. you have to use 67 full size SD cards. 68 69This information originally taken from: 70 71 https://wiki.linaro.org/Boards/MX6QSabreLite 72 73 743. Boot from SPI NOR 75-------------------- 76 77The SabreLite board can also boot U-Boot directly from the SPI NOR flash: 78 791. Power-up the SabreLite, press 'space' to enter command mode in the U-Boot 80 and enter the following commands: 81 82 => mmc dev 0 83 => mmc read 0x10800000 0x400 0x80000 84 => sf probe 0 85 => sf erase 0 0xc0000 86 => sf write 0x10800000 0x400 0x80000 87 88Note: This procedure assumes you have booted using the desired U-Boot from an 89 SD card as prepared in the previous section. Alternative mechanisms, such 90 as using tftpboot to copy an alternative U-Boot image into memory can 91 also be used. 92 93 944. Recovering SPI-NOR 95--------------------- 96 97In case you somehow do not succeed with this procedure you can upload U-Boot 98via USB: 99 1001. Download and install the imx_loader following the instructions provided: 101 102 https://github.com/boundarydevices/imx_usb_loader 103 1042. Connect the board to USB via the USB OTG port. 105 1063. Make sure SW1 switch is at position "01", so that it can boot from USB OTG. 107 1084. Power-up the SabreLite and run the imx_loader to upload the U-Boot image: 109 110 sudo imx_usb u-boot.imx 111 112Note: This will upload and run the U-Boot image in memory, the SPI will not be 113 reprogrammed and this procedure will need to be repeated if the board is 114 reset. 115 1165. Use one of previous descriptions to re-flash the SPI-NOR as required. 117 1186. Ensure SW1 is returned to "00" to boot from the fuses once done. 119 120
