This ++can be done with the following commands: ++ ++.. code-block:: none ++ ++ git clone git://github.com/boundarydevices/imx_usb_loader.git ++ cd imx_usb_loader ++ make ++ ++This will create the resulting imx_usb binary. ++ ++When this is done, you can copy the u-boot.imx image that you built earlier ++in in the imx_usb_loader directory. ++ ++You will then need to power off the TBS2910 Matrix ARM miniPC and make sure that ++the boot switch is set to "UPDATE" ++ ++Once this is done you can connect an USB cable between the computer that will ++run imx_usb and the TBS2910 Matrix ARM miniPC. ++ ++If you also need to access the u-boot console, you will also need to connect an ++UART cable between the computer running imx_usb and the TBS2910 Matrix ARM ++miniPC. ++ ++Once everything is connected you can finally power on the TBS2910 Matrix ARM ++miniPC. The SoC will then jump to the serial download and wait for you. ++ ++Finlay, you can load u-boot through USB with with the following command: ++ ++.. code-block:: none ++ ++ sudo ./imx_usb -v u-boot.imx ++ ++The u-boot boot messages will then appear in the serial console. ++ ++Install u-boot on the eMMC: ++--------------------------- ++To install u-boot on the eMMC, you first need to boot the TBS2910 Matrix ARM ++miniPC. ++ ++Once booted, you can flash u-boot.imx to mmcblk0boot0 with the ++following commands: ++ ++.. code-block:: none ++ ++ sudo echo 0 >/sys/block/mmcblk0boot0/force_ro ++ sudo dd if=u-boot.imx of=/dev/mmcblk0boot0 bs=1k seek=1; sync ++ ++Note that the eMMC card node may vary, so adjust this as needed. ++ ++Once the new u-boot version is installed, to boot on it you then need to power ++off the TBS2910 Matrix ARM miniPC. ++ ++Once it is off, you need make sure that the boot switch is set to "BOOT" and ++that the SW6 switch is set to boot on the eMMC as described in the previous ++sections. ++ ++If you also need to access the u-boot console, you will also need to connect an ++UART cable between the computer running imx_usb and the TBS2910 Matrix ARM ++miniPC. ++ ++You can then power up the TBS2910 Matrix ARM miniPC and U-Boot messages will ++appear in the serial console. ++ ++Booting a distribution: ++----------------------- ++When booting on the TBS2910 Matrix ARM miniPC, by default U-Boot will first try ++to boot from hardcoded offsets from the start of the eMMC. This is for ++compatibility with the stock GNU/Linux distribution. ++ ++If that fails it will then try to boot from several interfaces using ++'distro_bootcmd': It will first try to boot from the microSD slot, then the ++SD slot, then the internal eMMC, then the SATA interface and finally the USB ++interface. For more information on how to configure your distribution to boot, ++see 'README.distro'. ++ ++Links: ++------ ++ - https://www.tbsdtv.com/download/document/tbs2910/TBS2910-Matrix-ARM-mini-PC-SCH_rev2.1.pdf ++ - The schematics for the revision 2.1 of the TBS2910 Matrix ARM miniPC. ++ - https://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf - The ++ SoC reference manual for additional details on the BOOT_CFG registers. +-- +2.27.0 + diff --git a/libre/uboot4extlinux-imx/PKGBUILD b/libre/uboot4extlinux-imx/PKGBUILD index b6b7652a7..f4bb6aec0 100644 --- a/libre/uboot4extlinux-imx/PKGBUILD +++ b/libre/uboot4extlinux-imx/PKGBUILD @@ -4,14 +4,25 @@ # Contributor: Timothy Redaelli <timothy.redaelli@gmail.com> # Maintainer: Denis 'GNUtoo' Carikli <GNUtoo@cyberdimension.org> +# TODO: +# - Add the following boards +# - 'mx6cuboxi' +# - 'nitrogen6q' +# - 'udoo' +# - 'usbarmory' +# - 'wandboard' +# - Improve the .install: +# - Make it more generic: share the main part of the code. +# - Check for the machine name with the device tree and ask for confirmation +# if the machine is not the same but don't prevent users from installing +# this bootloader on a totally different machine as the installation could +# be done in a chroot or in other ways that packagers can't predict. +# - Handle more than one boot device (microSD, eMMC, USB, etc) +# - Point to the device documentation if there is some + pkgbase=uboot4extlinux-imx -pkgname=('uboot4extlinux-mx6cuboxi' - 'uboot4extlinux-nitrogen6q' - 'uboot4extlinux-tbs2910' - 'uboot4extlinux-udoo' - 'uboot4extlinux-usbarmory' - 'uboot4extlinux-wandboard') -pkgver=2020.01 +pkgname=('uboot4extlinux-tbs2910') +pkgver=2020.04 pkgrel=1 arch=('armv7h') url="http://git.denx.de/u-boot.git/" @@ -19,38 +30,40 @@ license=('GPL') makedepends=('bc' 'dtc' 'python' 'python2' 'swig') backup=(boot/extlinux/extlinux.conf) source=("ftp://ftp.denx.de/pub/u-boot/u-boot-${pkgver}.tar.bz2" - 'extlinux.conf' - 'tbs2910.h' - 'tbs2910_defconfig') -sha256sums=('aa453c603208b1b27bd03525775a7f79b443adec577fdc6e8f06974025a135f1' - 'SKIP' - 'SKIP' + 'extlinux.conf') + +sha256sums=('fe732aaf037d9cc3c0909bad8362af366ae964bbdac6913a34081ff4ad565372' 'SKIP') -# TODO -# boards=('mx6cuboxi' -# 'nitrogen6q' -# 'tbs2910' -# 'udoo' -# 'usbarmory' -# 'wandboard') +# Distro boot config and documentation for the TBS TBS2910 +# The patches are from the next branch of u-boot git +# a bit after the v2020.07-rc4 tag.
