Mh i guess NetLoop isn't called and thus NetOurEther is never initialized. Similar issue like d7310c7e63ca9ffd42527dc9735cb505cbe908b7. Initializing NetOurEther in net_init() fixes the problem. -- Michael

[U-Boot] [PATCH v7 00/15] split tegra20 arm7 code into separate SPL
by Allen Martin 23 Jul '12

23 Jul '12

This patch series fixes a long standing problem with the tegra20 u-boot build. Tegra20 contains an ARM7TDMI boot processor and a Cortex A9 main processor. Prior to this patch series this was accomplished by #ifdefing out any armv7 code from the early boot sequence and creating a single binary that runs on both both the ARM7TDMI and A9. This was very fragile as changes to compiler options or any additions or rearranging of the early boot code could add additional armv7 specific code causing it to fail on the ARM7TDMI. This patch series pulls all the armv4t code out into a separate SPL that does nothing more than initialize the A9 and transfer control to it. The resultint SPL and armv7 u-boot are concatenated together into a single image. This patch series is also available from: git://github.com/arm000/u-boot.git branch: tegra-spl-v7 Changes: v7: - rebased to u-boot-tegra/next - added Acks and Tested-Bys v6: - changed combined SPL/u-boot target names to u-boot-dtb-tegra.bin and u-boot-nodtb-tegra.bin - fixed regression introduced in v5 that caused git bisect to fail to build at one of the patches - fix USE_PRIVATE_LIBGCC for SPL build and enable it - fix libtegra20-common.so link so it works if building with out of tree OBJDIR v5: - added missing mkdir rules in all tegra20 board Makefiles that include common code and changed them to be unconditional - make new u-boot-dtb-t2.bin rule default for tegra20 and copy resulting binary over u-boot.bin v4: - rebased to u-boot-tegra/next - reordered entire patch series to preserve git bisect, verified build and boot at each patch - merged patches that add SPL config defines and removes duplicate code from u-boot init, these have to go in atomically to preserve building at each patch - fixed compiler warnings introduced - fixed blank line at end of file on cpu.c - renamed u-boot.t2 to u-boot-t2.bin - cleaned up config.mk generation in mkconfig to make it more readable - added some text to clarify using arm720t code for arm7tdmi - rearranged SPL memory map to make resulting SPL + u-boot image much smaller - removed separate PAD_TO define in favor of just using CONFIG_SYS_TEXT_BASE - moved warmboot_save_sdram_params() from dram_init() to board_init() v3: - git bisect still does not work across this series, I'm saving that for the next revision, but I had enough changes that I wanted to get this out for review - expanded the tegra2 -> tegra20 rename to include functions/variables/ defines - rebased to u-boot-tegra/next - removed some extra -march=armv4t flags, kept armv4t flags on warmboot_avp since it's special - removed bashisms from mkconfig - renamed CONFIG_MACH_TEGRA_GENERIC to CONFIG_TEGRA - moved SPL overrides to tegra2-common-post.h - changed SPL base address to 0x108000, u-boot goes to 0x208000 - moved warboot_save_sdram_params fix to separate patch - remove USE_PRIVATE_LIBGCC from non SPL build - expanded SPL support to all tegra20 boards, not just seaboard v2: - renamed tegra2 to tegra20 to match kernel and devicetree naming policy - pulled all SPL related config overrides to a separate file to clean up ifdefs from seabard.h - rebased to TOT u-boot/master and fixed a bug related to init sequence changes between this patch series and new EMC code - made u-boot.t2 target work even if CONFIG_OF is disabled - added back USE_PRIVATE_LIBGCC Allen Martin (15): tegra20: rename tegra2 -> tegra20 tegra20: move tegra20 SoC code to arch/arm/cpu/tegra20-common tegra20: rename CONFIG_MACH_TEGRA_GENERIC

I agree. I don't have time to fix this right now. Perhaps you or someone else can handle this. There does not seem to be any bug tracking system in U-Boot, so I don't know if something specific should be done to report this. Anyway, this does not seem to be an issue for current hardware using this driver, so there is no emergency. I also noticed that fec_eth_phy_config calls phy_connect with PHY_INTERFACE_MODE_RGMII regardless of xcv_type, which does not seem appropriate. Best regards, Benoît

[U-Boot] Uboot and initramfs
by Wojtek 23 Jul '12

23 Jul '12

Hi, I'm struggling with the topic for long two days and I want to ask for help. I have a DNS-320 system with u-boot. I compiled kernel and it works well, but I need initramfs. I prepared contents on this system (ARM) (no need to cross-compile), then did: find . -print0 | cpio --null -ov --format=newc | gzip -9 > initramfs mkimage -A arm -O linux -T ramdisk -C gzip -n "Some name" -d initramfs initramfs.kwb flash_eraseall /dev/mtd2 nandwrite -p /dev/mtd2 ./initramfs.kwb reboot Marvell_DNS320>> nand read.e 0xa00000 0x100000 0x200000 NAND read: device 0 offset 0x100000, size 0x200000 load addr .... =a00000 2097152 bytes read: OK Marvell_DNS320>> nand read.e 0xf00000 0x600000 0x500000 NAND read: device 0 offset 0x600000, size 0x500000 load addr .... =f00000 5242880 bytes read: OK Marvell_DNS320>> bootm 0xa00000 0xf00000 ## Booting image at 00a00000 ...
