[U-Boot] [PATCH] cmd, nand: fix broken output of "nand info"
by Lothar Waßmann 10 Jul '17

10 Jul '17

If the value of either "nand options" or "bbt options" has a zero in the most significant nibble, the '0x' prefix will be isolated from the value like shown below: |Device 0: nand0, sector size 128 KiB | Page size 2048 b | OOB size 64 b | Erase size 131072 b | subpagesize 2048 b | options 0x40000200 | bbt options 0x 60000 Change the format string to produce leading zeroes filling the gap.

[U-Boot] [ANN] U-Boot v2017.07-rc2 released
by Tom Rini 10 Jul '17

10 Jul '17

Hey all, It's release day and v2017.07-rc2 is out. I'm mostly happy with the size of the changes here and I did remember to sync the defconfigs prior to tagging. If anyone has critical fixes I've missed or some Kconfig migrations (that I can prove out as correct), please speak up. Things look on track for -rc3 on July 3rd and release on July 10th. Thanks all! -- Tom

[U-Boot] U-Boot image with multiple u-Boot dt blobs selected at low level boot
by Oliver Westermann 10 Jul '17

10 Jul '17

Hello, I've got multiple ARM boards with similar but not quite the same configurations. For example different IO configurations for peripheral reset lines of hardware used in the u-boot phase. Currently I have multiple u-Boot configurations using multiple .dts files creating multiple u-boot.img and MLO files which are stored on the devices emmc (one set on every device). The u-boot than loads the linux kernel and the device specific linux dtb from a FAT partition on the device and boots (The linux partition has one kernel and multiple .dtb, so it supports all devices). The differences between the boards are GPIO related, but also power configuration & regulator settings. I would prefer to have a single u-boot.img and MLO file set to load onto all my devices. When I search the docs for this issue, I find many hints pointing me to u-boot FIT images, but from my point of view FIT issues multiple LINUX kernel and dt-blobs, not dt-blobs and configuration on the u-boot level. What would be the cleanest solution to load one uboot image, which has different behavior depending on the device it boots from? Best regards, Olli

Hello, I wishb to run this RTOS: https://github.com/trampolinertos/trampoline, on Zedboard having these files on SD card. SD_ROOT/ boot.bin devicetree.dtb uImage uramdisk.image.gz How can I build u-boot and dtb for this RTOS and make u-boot load the rtos instead of Linux ? Thank you ᐧ

[U-Boot] Arria 10 binary too large
by Joe Hermaszewski 10 Jul '17

10 Jul '17

The uboot binary generated with `make socfpga_arria10_config` is too large for Intel's `mkpimage` tool to consume. u-boot.bin weighs in at 242508 bytes. The maximum binary size supported by the `mkpimage` tool (distributed with Intel's SoC EDS suite) is 204796 bytes. Note that this image also has to include the device tree blob, which for my design is about 4k. I'm sure that someone must have tested this binary, it would be handy to know either what configuration options were necessary to slim u-boot down enough, or how mkpimage might be being used differently. For reference, my build steps are as follows: To generate u-boot.bin: ``` export CROSS_COMPILE=${soc-toolchain}/bin/arm-linux-gnueabihf- make mrproper make socfpga_arria10_config make ``` To generate uboot combined with the device tree blob: ``` cat u-boot.bin devicetree.dtb > u-boot_w_dtb.bin mkpimage \ --header-version 1 \ -o uboot_w_dtb-mkpimage.bin \ u-boot_w_dtb.bin \ u-boot_w_dtb.bin \ u-boot_w_dtb.bin \ u-boot_w_dtb.bin ``` mkpimage fails with the output 'Image size must not be more than 204796 bytes' I get this behaviour with `mkpimage version 17.0 (build 290)` and revision `7e09145` of u-boot. Best, Joe.

[U-Boot] [PATCH 00/12] tegra: nyan-big: Support chainloading and add documentation
by Simon Glass 09 Jul '17

09 Jul '17

Every now and then someone wants to chain-load U-Boot on a Chromebook. The procedure is not very complicated but there are some oddities. This series updates a few things with allow U-Boot to start on nyan-big in this way and adds documentation on how to do it. This provides a central place where the procedure on different devices can be documented.
