Das U-Boot for UDOO

UDOO U-Boot

UDOO Neo

To build the U-Boot for UDOO Neo, use the 2015.04.imx branch. This branch is based on Freescale's U-Boot (uboot-imx) version 2015.04.

The build can be started with:

ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make udoo_neo_defconfig
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make

The produced files, SPL and u-boot.img, can be used to boot all Neo variants (basic, basic kickstarter, extended, full).

UDOO Quad/Dual

To build the U-Boot for UDOO Quad/Dual, use the 2015.10.fslc-qdl branch. This branch is based on Freescale's U-Boot (uboot-imx) version 2015.10.

The build can be started with:

ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make udoo_qd_config
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make

The produced files, SPL and u-boot.img, can be used to boot both Quad and Dual boards.

B08 board

To build the U-Boot for Seco B08, use the 2015.04.imx branch. This branch is based on Freescale's U-Boot (uboot-imx) version 2015.04.

The build can be started with:

ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- ./compile_b08.sh

The produced files: SPL, u-boot.imx and u-boot.spi can be used to boot from uSD ard and SPI flash. To write SPI flash format the memory (flash_erase) and after execute:

 dd if=u-boot.spi of=/dev/mtd0 bs=1k seek=1 

SD card flashing

Flash your /dev/mmcblk0 SD card with:

dd if=SPL of=/dev/mmcblk0 bs=1K seek=1
dd if=u-boot.img of=/dev/mmcblk0 bs=1K seek=69

uboot-imx's Issues

there is a build error

Patching LVDS for Arch Linux ARM

I've been planning on patching the LVDS functionality into Arch Linux ARM with the udoo quad (so I can use the 15" non-touch Innolux panel) and have a few noob questions. I've looked here at your source uboot and there doesn't appear to be anything regarding LVDS for the quad...

Also, will I need to patch the kernel as well or only the uboot?

PLAIN_VERSION undeclared

Hi,

Building u-boot following the provide guidelines:

ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make udoo_neo_config
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make

I get the following error:
tools/mkenvimage.c: In function ‘main’:
tools/mkenvimage.c:120:35: error: ‘PLAIN_VERSION’ undeclared (first use in this function)
printf("%s version %s\n", prg, PLAIN_VERSION);

I can't figure out from where it come neither how to fix it.

Is anybody able to help here ?

Regards,
Jeremy.

OpenWrt support

Hello guys,

I'm trying to add OpenWrt support for UDOO Neo but I'm having some issues, and it would be great if I could get some help from anyone :).

First of all I need to be able to build a functional uboot from OpenWrt environment.
In order to do so, I used the patches available in the "2015.04+fsl_NEO" branch of this repo:
openwrt-es/openwrt@1aec79e
https://github.com/openwrt-es/openwrt/tree/imx6-udoo-neo/package/boot/uboot-imx6/patches
As you can see, patches 120-131 are the ones extracted from this repository, and patches 140/141 are hacks done to make it compile, since it would complain about undefined FSL_QSPI_FLASH_SIZE/FSL_QSPI_FLASH_NUM (patch 140) and about not having a defconfig for the basic version (141).

BTW, the kernel support part is also done, but I can't check if it needs any fixes until I get a working bootloader: openwrt-es/openwrt@ce5b518

P.S: Github repo & branch: https://github.com/openwrt-es/openwrt/commits/imx6-udoo-neo

U-Boot SPL

I am wondering if anyone thinks to support U-Boot SPL (Secondary Program Loader)? It would simplify using Udoo dual and quad with only one bootloader (same image for both devices).

Seems no interest that's why I will try to make it. Based on wandboard spl with the help of Fabio Estevam.

Kernel reset

Hi all,

I am facing an issue with this U-boot version, the Linux kernel seems to be loaded just fine but at the middle of loading all the modules the board resets and U-boot starts again. I suspect of the watchdog but I am not really sure (I'm a beginner).

To compile I do the following:
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make udoo_qd_defconfig
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make

When I compile I get the following warnings:
board/udoo/udoo_qd/udoo.c:180:13: warning: ‘setup_iomux_wdog’ defined but not used [-Wunused-function]
static void setup_iomux_wdog(void)

board/udoo/udoo_qd/udoo.c:180:13: warning: ‘setup_iomux_wdog’ defined but not used [-Wunused-function]
static void setup_iomux_wdog(void)

Using the image that is on the web it boots without issue and I think the only difference is that this version of U-boot is 2015.04 and the one in the image is U-boot 2015.10.

Thanks!
