[U-Boot-Users] Loading U-boot using BDI - PPC440GX Taishan Eval Board
by Sean 21 Feb '08

Hi, I'm using the BDI config file for Taishan Eval Board from http://www.denx.de/wiki/view/DULG/Appendix#Section_13.1. I verified all the values and they are fine. Any idea, what I'm missing here? taishan>unlock 0xfffc0000 0x20000 2 Unlocking flash at 0xfffc0000 # Invalid parameter for flash programming taishan>unlock 0xfffc0000 0x10000 2 Unlocking flash at 0xfffc0000 # Invalid parameter for flash programming taishan> Thanks, -- Senthil

[U-Boot-Users] [PATCH 0/6] [new uImage] patchset4 - assorted patches
by Bartlomiej Sieka 21 Feb '08

21 Feb '08

This patchset encompasses some clean-ups and fixes, and adds the new uImage #define knob (CONFIG_FIT), which is enabled by default. The patchset also adds some new uImage-specific functionality: (1) a routine to parse new-style arguments to bootm (and other commands), (2) a generic function for retrieving images. It lays foundation for the soon-to-follow: - low-level new uImage handling functions - mkimage extensions to allow generation of new format images - U-Boot support for booting new format images Code from this patchset will be soon available from the new-image branch of the u-boot-testing repository. Please review, test and provide comments. Marian Balakowicz (6): [new uImage] Fix erroneous use of image_get_magic() in fdc/usb cmds [new uImage] Rename and move print_image_hdr() routine [new uImage] Add fit_parse_conf() and fit_parse_subimage() routines [new uImage] Add gen_get_image() routine [libfdt] Fix compilation errors is fdt_support.c [new uImage] Pull in libfdt if CONFIG_FIT is enabled Regards, Bartlomiej

[U-Boot-Users] lwmon5: enable hardware watchdog
by Wolfgang Denk 21 Feb '08

21 Feb '08

From: Yuri Tikhonov <yur(a)emcraft.com> Some boards (e.g. lwmon5) may use rather small watchdog intervals, so causing it to reboot the board if U-Boot does a long busy-wait with udelay(). Thus, for these boards we have to restart WD more frequently. This patch splits the busy-wait udelay() into smaller, predefined, intervals, so that the watchdog timer may be resetted with the configurable (CONFIG_WD_PERIOD) interval.

[U-Boot-Users] Fix CPU POST test failure
by Wolfgang Denk 21 Feb '08

21 Feb '08

From: Yuri Tikhonov <yur(a)emcraft.com> The CPU POST test code (run from cpu_post_exec_31()) doesn't follow the ABI carefully, at least the CR3, CR4, and CR5 fields of CR are clobbered by it. The gcc-4.2 with its more aggressive optimization exposes this fact. This patch just saves the CR value before running the test code, so allowing it to do anything it wants with CR.

[U-Boot-Users] uboot on MPC5516
by Tehn Yit Chin 21 Feb '08

21 Feb '08

I was wondering if there is any current work for supporting MPC5516. I was not able to find any specific support in u-boot 1.3.1 for Freescale's MPC5516. I can only find generic support for MPC5xxx, in particular MPC5200. I am currently evaluating u-boot, but am not certain if it will be able to support the the second core in the MPC5516 which only executes in VLE mode. Any comments? Many thanks, Tehn Yit Chin
