Hi I am working on a custom board (VPX Based P2020 board) and trying to port u-boot-2011.09 (supports P2020 RDB) in it . Our board is similar to P2020RDB board and the technical specification is shown below , ->Processor Freescale QorIQ P2020 processor Dual PowerPC e500v2 cores at up to 1.2 GHz 512 kB of shared L2 cache ->Memory 1 GB of DDR3-600 SDRAM 128 MB of NOR flash (16-bit) Through Codewarroier Emulator Tool, We checked the DDR,FLASH,Uart console and its working fine without any issue. when we ported u-boot (u-boot-2011.09) at boot rom location 0xFFF80000, it fails at invalidate_tlbs in cpu_init_early_f and cannot proceed to get serial console .we probed the flash CS while poweron boot , processor is keeping bunch of CS( confirms processor able to access flash) Why its getting held up while invalidating tlb's Can you help us to solve the issue -- View this message in context: http://old.nabble.com/P2020rdb-%3A--process-hangs-while-invalidate_tlb%27s-… Sent from the Uboot - Users mailing list archive at Nabble.com.

[U-Boot] mx53loco: Fix build error when CONFIG_VIDEO is disabled
by Vikram Narayanan 14 Nov '12

14 Nov '12

The inclusion of LCD patch into mx51evk breaks the build when CONFIG_VIDEO is disabled. Fix this by splitting the video related stuff to a new file. Also rename the function lcd_iomux to setup_iomux_lcd to make the namings aligned with the other iomux functions.

From: "Jens Scharsig (BuS Elektronik)" <esw(a)bus-elektronik.de> - update clock settings for higher perfomance - change standard baud rate to 115200 - fix flash base address - remove unused defines - add I2C support - switch form board dependent flash to cfi - remove board dependent flash code - use sdram bank 0 instead of bank 1 on boot - enable on board frame buffer instead external - remove fake mac address form config - add watchdog support - add status led support Signed-off-by: Jens Scharsig (BuS Elektronik) <esw(a)bus-elektronik.de> --- board/BuS/eb_cpu5282/Makefile | 2 +- board/BuS/eb_cpu5282/cfm_flash.c | 212 ------------------- board/BuS/eb_cpu5282/cfm_flash.h | 40 ---- board/BuS/eb_cpu5282/config.mk | 27 --- board/BuS/eb_cpu5282/eb_cpu5282.c | 102 ++++++--- board/BuS/eb_cpu5282/flash.c | 415 ------------------------------------- boards.cfg | 2 +- include/configs/eb_cpu5282.h | 101 +++++---- 8 files changed, 142 insertions(+), 759 deletions(-) delete mode 100644 board/BuS/eb_cpu5282/cfm_flash.c delete mode 100644 board/BuS/eb_cpu5282/cfm_flash.h delete mode 100644 board/BuS/eb_cpu5282/config.mk delete mode 100644 board/BuS/eb_cpu5282/flash.c diff --git a/board/BuS/eb_cpu5282/Makefile b/board/BuS/eb_cpu5282/Makefile index 0f14699..ac860c1 100644 --- a/board/BuS/eb_cpu5282/Makefile +++ b/board/BuS/eb_cpu5282/Makefile @@ -25,7 +25,7 @@ include $(TOPDIR)/config.mk LIB = $(obj)lib$(BOARD).o -COBJS = $(BOARD).o cfm_flash.o flash.o +COBJS = $(BOARD).o SRCS := $(SOBJS:.o=.S) $(COBJS:.o=.c) OBJS := $(addprefix $(obj),$(COBJS)) diff --git a/board/BuS/eb_cpu5282/cfm_flash.c b/board/BuS/eb_cpu5282/cfm_flash.c deleted file mode 100644 index fe03b17..0000000 --- a/board/BuS/eb_cpu5282/cfm_flash.c +++ /dev/null @@ -1,212 +0,0 @@ -/* - * Basic Flash Driver for Freescale MCF 5281/5282 internal FLASH - * - * (C) Copyright 2005 BuS Elektronik GmbH & Co.KG <esw(a)bus-elektonik.de> - * - * See file CREDITS for list of people who contributed to this - * project. - * - * This program is free software; you can redistribute it and/or - * modify it under the terms of the GNU General Public License as - * published by the Free Software Foundation; either version 2 of - * the License, or (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[U-Boot] [PATCH 1/2] tegra: i2c: Add function to know about current bus

Rather than using a variable in various places, add a single function, tegra_i2c_get_bus(), which returns a pointer to information about a bus.

Hey. I wrote a utility to boot Marvell SoCs over serial. If that sounds generally useful, would you be so kind to merge git://github.com/dns42/u-boot.git at dns/kwboot-1 If it's missing sth for that to happen, lemme know. Cheers, Daniel

HI, After power short u-boot fails to mount UBIFS and board stuck. Below is a trace of u-boot Marvell>> boot UBI: mtd1 is detached from ubi0 Creating 1 MTD partitions on "nand0": 0x000000500000-0x000020000000 : "mtd=2" UBI: attaching mtd1 to ubi0 UBI: physical eraseblock size: 131072 bytes (128 KiB) UBI: logical eraseblock size: 129024 bytes UBI: smallest flash I/O unit: 2048 UBI: sub-page size: 512 UBI: VID header offset: 512 (aligned 512) UBI: data offset: 2048 UBI: attached mtd1 to ubi0 UBI: MTD device name: "mtd=2" UBI: MTD device size: 507 MiB UBI: number of good PEBs: 4055 UBI: number of bad PEBs: 1 UBI: max. allowed volumes: 128 UBI: wear-leveling threshold: 4096 UBI: number of internal volumes: 1 UBI: number of user volumes: 1 UBI: available PEBs: 0 UBI: total number of reserved PEBs: 4055 UBI: number of PEBs reserved for bad PEB handling: 40 UBI: max/mean erase counter: 1/0 UBIFS: recovery needed Error reading superblock on volume 'ubi:rootfs'! UBIFS not mounted, use ubifs mount to mount volume first! UBIFS not mounted, use ubifs mount to mount volume first! Wrong Image Format for bootm command ERROR: can't get kernel image! Marvell>> To recover from this situation I boot from USB stick and simply mounts the same UBIFS partition: root@debian:~# mount -t ubifs ubi0:rootfs /mnt [ 306.205029] UBIFS: recovery needed [ 309.341987] UBIFS: recovery completed [ 309.345705] UBIFS: mounted UBI device 0, volume 0, name "rootfs" [ 309.351738] UBIFS: file system size: 515192832 bytes (503118 KiB, 491 MiB, 3993 LEBs) [ 309.359789] UBIFS: journal size: 25804800 bytes (25200 KiB, 24 MiB, 200 LEBs) [ 309.367495] UBIFS: media format: w4/r0 (latest is w4/r0) [ 309.373352] UBIFS: default compressor: lzo [ 309.377479] UBIFS: reserved for root: 4952683 bytes (4836 KiB) As you can see mount manage to recover partition. Is where any way to make u-boot to recover UBIFS partition as well? What else can I do to make my system stable and survive power shorts? Thanks.
