[U-Boot] Booting image from ARM for different architecture
by Michal Simek 02 Apr '14

02 Apr '14

Hi all, I want to check with you if someone tried this scenario. Load u-boot on main CPU (for me ARM cortex-a9) and boot different cpu(for me Microblaze) with FIT image or old u-boot image format. IRC I have seen any code regarding this but I am not able to find it out where. :-( My current usage is that I do that steps by hand by tftp 100000 kernel.bin (microblaze kernel in bin format with rootfs and dtb in it) mwr 0xXXXXXX 0x1 (turn on microblaze via custom logic which jumps to 0x100000) tftp 10000000 image.ub (download arm kernel) bootm 0x10000000 (boot arm kernel) I think that will be much better to have both kernels in one FIT image and and use two configurations. One for microblaze kernel and second for arm kernel and boot it with one bootm command. Simon: Is this configuration even supported by FIT image? Thanks, Michal -- Michal Simek, Ing.

[U-Boot] CONFIG_REMAKE_ELF for aarch64
by York Sun 02 Apr '14

02 Apr '14

Scott, I am having a problem recreating u-boot.elf for aarch64 targets. The file is OK when Ttext is aligned with 64KB boundary, for example 0x30000000. But if I use 0x30001000 as the text base, the result u-boot.elf has additional offset of 0x10000. For example, the first instruction should be (from objdump) 30001000: 1400000a b 30001028 But it is 30011000: 1400000a b 30011028 My gcc version is gcc version 4.8.3 20131202 (prerelease) (crosstool-NG linaro-1.13.1-4.8-2013.12 - Linaro GCC 2013.11) GNU ld (crosstool-NG linaro-1.13.1-4.8-2013.12 - Linaro GCC 2013.11) 2.24.0.20131220 Supported emulations: aarch64linux aarch64elf aarch64elf32 aarch64elf32b aarch64elfb armelf armelfb aarch64linuxb aarch64linux32 aarch64linux32b armelfb_linux_eabi armelf_linux_eabi I am hoping you or someone familiar with ABI or something related and shed some light.

The u-boot's image TEXT_BASE needs to be changed to 0x43e00000 from 0x78100000. This change provides compatibility with other trats2 (RD_PQ) devices (http://download.tizen.org/releases/system/).
