[U-Boot] [PATCH RESEND] test/py: skip tests that require large CONFIG_SYS_MAXARGS
by Stephen Warren 26 Feb '16

26 Feb '16

test_hush_if_test.py executes commands that require large values of CONFIG_SYS_MAXARGS. Detect cases where the configured value is too low and skip those tests. Ideally, this would be implemented inside console.run_command(). However, the command passed to that function is already a completely formed string, and determining its argument count usage would require splitting commands at ;, handling quoting to deal with arguments containing spaces, etc. Even passing the command as a list wouldn't solve all these issues, since we'd still need to split commands on ; and deal with cases like "if test ..." which consumes 0 of the argument count.

[U-Boot] [PATCH RESEND] test/py: use space to interrupt autoboot
by Stephen Warren 26 Feb '16

26 Feb '16

Sending CTRL-C to QEMU's stdin aborts the process, even if stdin is being used as a serial port (at least in the raspi2 machine with "qemu -serial stdin"). Avoid sending CTRL-C to U-Boot to prevent it exiting. I'd originally used CTRL-C to make sure that if the character used to abort autoboot ended up being treated as part of a command as well, it'd abort command entry and return the prompt to a known state. However, this is not needed, since aborting the autoboot eats the character used to do that.

[U-Boot] Problems loading Linux in A33
by Antonio Fernandez 26 Feb '16

26 Feb '16

Hi, I am trying to load linux in my Chinese device A33_ET_Q8. I have managed to create a bootable SD card to load the u-boot-sunxi-with-spl.bin file, the script.bin file, the boot.scr file and the sun8i-a33-q8-tablet.dtb file, but the system is getting stuck when the kernel is loading. I have attached a small video to check the problem. I don't know the right configuration files for this tablet, so I am using the configuration files from other similar tablets. Can someone give some advice to move forward with this problem? Thanks a lot for the help! Toni

[U-Boot] [PATCH v2 1/2] serial: dcc: Move driver to DM

[U-Boot] [PATCH v4 00/15] EFI payload / application support
by Alexander Graf 26 Feb '16

26 Feb '16

This is my (now very late) Christmas present for my openSUSE friends :). U-Boot is a great project for embedded devices. However, convincing everyone involved that only for "a few oddball ARM devices" we need to support different configuration formats from grub2 when all other platforms (PPC, System Z, x86) are standardized on a single format is a nightmare. So we started to explore alternatives. At first, people tried to get grub2 running using the u-boot api interface. However, FWIW that one doesn't support relocations, so you need to know where to link grub2 to at compile time. It also seems to be broken more often than not. And on top of it all, it's a one-off interface, so yet another thing to maintain. That led to a nifty idea. What if we can just implement the EFI application protocol on top of U-Boot? Then we could compile a single grub2 binary for uEFI based systems and U-Boot based systems and as soon as that one's loaded, everything looks and feels (almost) the same. This patch set is the result of pursuing this endeavor. - I am successfully able to run grub2 and Linux EFI binaries with this code. - When enabled, the resulting U-Boot binary only grows by ~10kb, so it's very light weight. - It works on 32bit ARM and AArch64. - All storage devices are directly accessible - No EFI variables - Removable media booting (search for /efi/boot/boota{a64,arm}.efi) - Everything in place for runtime service support Of course, there are still a few things one could do on top: - Improve disk media detection (don't scan, use what information we have) - Add EFI variable support using NVRAM - Add GFX support - Make EFI Shell work ;) - Network device support - Support for payload exit But so far, I'm very happy with the state of the patches. They completely eliminate potential arguments against U-Boot internally and give users the chance to run with the same level of comfort on all firmware types. Version 4 was successfully tested to boot grub2 and Linux from there on a HiKey. Please apply the arm64 mmu patch set if you want to run this on an AArch64 system.
