[U-Boot] nand sector size is zero in jffs2 cmds
by Derek Ou 27 Jan '09

27 Jan '09

Hi, all, When I tested jffs2 command for NAND, I found that jffs2_1pass.c:: jffs2_1pass_build_lists() fails at u32 nr_sectors = part->size/part->sector_size; because part->sector_size is zero. And cause the "### ERROR ### Please RESET the board ###" error when entering the for loop (i < nr_sectors), I think. It looks like the sector_size was not updated in mtdparts_init(). According to cmd_jffs2.c, the mtdparts_init in the #ifdef CONFIG_JFFS2_CMDLINE section calls the parse_mtdparts() and eventually reach the following lines in part_validate_nand(): nand = &nand_info[id->num]; part->sector_size = nand->erasesize; However, the other mtdparts_init(), which is not in the #ifdef CONFIG_JFFS2_CMDLINE section, does not call parse_mtdparts() and it may lead to the part->sector_size not initialized. I am not totally familiar with this jffs2 and nand code. Can someone review this? Thanks. Derek

[U-Boot] fat.c:707: warning: array subscript is above array bounds
by Wolfgang Denk 27 Jan '09

27 Jan '09

Hello, building U-Boot with recent toolchains (like GCC-4.3.2) results in this warning: fat.c: In function 'read_bootsectandvi': fat.c:707: warning: array subscript is above array bounds The respective code looks like this: fs/fat/fat.c: 705 /* Terminate fs_type string. Writing past the end of vistart 706 is ok - it's just the buffer. */ 707 vistart->fs_type[8] = '\0'; fs_type[] is declared in "include/fat.h": 143 typedef struct volume_info 144 { 145 __u8 drive_number; /* BIOS drive number */ 146 __u8 reserved; /* Unused */ 147 __u8 ext_boot_sign; /* 0x29 if fields below exist (DOS 3.3+) */ 148 __u8 volume_id[4]; /* Volume ID number */ 149 char volume_label[11]; /* Volume label */ 150 char fs_type[8]; /* Typically FAT12, FAT16, or FAT32 */ 151 /* Boot code comes next, all but 2 bytes to fill up sector */ 152 /* Boot sign comes last, 2 bytes */ 153 } volume_info; So the comment in fs/fat/fat.c is actually correct, writing beyond the end of the string is indeed uncritical here, but it is definitely not really nice either. I want to get rid of this warning message. Any ideas how to deal with this?

[U-Boot] [PATCH] ne2000: take MAC address from config if available
by Daniel Mack 27 Jan '09

27 Jan '09

Hi, the board I'm currently working on has an ASIX AX88796 NE2000 clone but no EEPROM attached to it. Hence, the get_prom() routine returns zeros only so the system won't work. This patch takes the MAC address given by CONFIG_ETHADDR and translates it to numeric values. This could probably go to some other, more generic place, but I didn't find any. Best regards, Daniel diff --git a/drivers/net/ne2000_base.c b/drivers/net/ne2000_base.c index f93f932..f8480a3 100644 --- a/drivers/net/ne2000_base.c +++ b/drivers/net/ne2000_base.c @@ -693,6 +693,7 @@ int eth_init(bd_t *bd) { nic.base = (u8 *) CONFIG_DRIVER_NE2000_BASE; +#ifndef CONFIG_ETHADDR r = get_prom(dev_addr, nic.base); if (!r) return -1; @@ -703,6 +704,20 @@ int eth_init(bd_t *bd) { dev_addr[4], dev_addr[5]) ; PRINTK("Set environment from HW MAC addr = \"%s\"\n", ethaddr); setenv ("ethaddr", ethaddr); +#else /* CONFIG_ETHADDR */ +#define STR(X) #X +#define XSTR(X) STR(X) + strncpy(ethaddr, XSTR(CONFIG_ETHADDR), sizeof(ethaddr)); + + /* replace all colons by NULL characters */ + for (r = 0; r < strlen(ethaddr); r++) + if (ethaddr[r] == ':') + ethaddr[r] = '\0'; + + /* convert the string notation */ + for (r = 0; r < 6; r++) + dev_addr[r] = simple_strtol(ethaddr + (r * 3), NULL, 16); +#endif nic.data = nic.base + DP_DATA; nic.tx_buf1 = START_PG;

[U-Boot] [PATCH 0/2] CFI: increase performance
by Jens Gehrlein 26 Jan '09

26 Jan '09

Hi list, The following patches should increase the performance of the CFI driver, particularly with regard to single word programming mode. I tested it on TQM5200S with NOR-Flash Samsung K8P2815UQB, which has no write buffer. At least no write buffer, that could be programmed using standard commands. Performance increase on this TQM is about factor 2.6 (37 KiB/s -> 95 KiB/s). On the same module with Spansion S29GL128N (with write buffer) it is about factor 1.2 (455 KiB/s -> 585 KiB/s). TQM5200 is a bottom boot module with 2x16 Bit Flash connection. Could someone test the patches on other HW, particularly top boot, other CPU, other flash width, please? Thanks, Jens --- Jens Gehrlein (2): CFI: increase performance of function find_sector() CFI: avoid redundant function call in single word programming mode drivers/mtd/cfi_flash.c | 33 +++++++++++++++++++++++---------- 1 files changed, 23 insertions(+), 10 deletions(-)

[U-Boot] [PATCH 00/15] i386 Modifications and new board (eNET)
by Graeme Russ 26 Jan '09

26 Jan '09

The following patch series follows from a previous set of preliminary i386 patches (see http://lists.denx.de/pipermail/u-boot/2008-November/043681.html) This set of patches adds supports for the board I am developing with (eNET) and makes a few changes to the arrangement of the i386 code in U-Boot. These changes are intended to provide better hooks for cpu and board specific functionality. This patch series includes support for the SC520 MMCR reset functionality which was implied by the configuration options but never implemented. A couple of minor tidy-ups have been performed (moved ali512x.h to a more logical location, changed the configuration settings to CONFIG_SYS_ for example). This patch set, however, is not a full scale style cleanup. There may be places where non-conforming style has been used - For the time being, I am focusing on getting code into the right place. A more complete coding style cleanup will follow. Regards, Graeme

[U-Boot] [PATCH V3] Initial support for Nomadik 8815 development
by Alessandro Rubini 24 Jan '09

24 Jan '09

From: Alessandro Rubini <rubini(a)unipv.it> Subject: Initial support for Nomadik 8815 development board The NMDK8815 board is distributed by ST Microelectornics. Other (proprietary) code must be run to unlock the CPU before U-Boot runs. doc/README.nmdk8815 outlines the boot sequence. This is the initial port, with basic infrastructure and a working serial port. Signed-off-by: Alessandro Rubini <rubini(a)unipv.it> Acked-by: Andrea Gallo <andrea.gallo(a)stnwireless.com> --- changes since v2: - added doc/README.nmdk8815 to explain the boot process - moved code to a vendor dir - fixed Makefiles as suggested (and removed unused CFLAGS) - added copyright where missing (u-boot.lds is copied, so no new copyright) - fixed remaining whitespace issues and comment style - other detais JC noted MAINTAINERS | 5 + MAKEALL | 1 + Makefile | 11 ++ board/st/nmdk8815/Makefile | 55 +++++++ board/st/nmdk8815/config.mk | 26 +++ board/st/nmdk8815/nmdk8815.c | 73 +++++++++ board/st/nmdk8815/platform.S | 345 ++++++++++++++++++++++++++++++++++++++++ board/st/nmdk8815/u-boot.lds | 51 ++++++ cpu/arm926ejs/nomadik/Makefile | 46 ++++++ cpu/arm926ejs/nomadik/reset.S | 27 +++ cpu/arm926ejs/nomadik/timer.c | 180 +++++++++++++++++++++ doc/README.nmdk8815 | 22 +++ include/configs/nmdk8815.h | 188 ++++++++++++++++++++++ 13 files changed, 1030 insertions(+), 0 deletions(-) create mode 100644 board/st/nmdk8815/Makefile create mode 100644 board/st/nmdk8815/config.mk create mode 100644 board/st/nmdk8815/nmdk8815.c create mode 100644 board/st/nmdk8815/platform.S create mode 100644 board/st/nmdk8815/u-boot.lds create mode 100644 cpu/arm926ejs/nomadik/Makefile create mode 100644 cpu/arm926ejs/nomadik/reset.S create mode 100644 cpu/arm926ejs/nomadik/timer.c create mode 100644 doc/README.nmdk8815 create mode 100644 include/configs/nmdk8815.h diff --git a/MAINTAINERS b/MAINTAINERS index 127604b..e2a90d2 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -581,6 +581,11 @@ Stefan Roese <sr(a)denx.de> pdnb3 xscale scpu xscale +Alessandro Rubini <rubini(a)unipv.it> +Nomadik Linux Team <STN_WMM_nomadik_linux(a)list.st.com> + + nmdk8815 ARM926EJS (Nomadik 8815 Soc) + Robert Schwebel <r.schwebel(a)pengutronix.de> csb226 xscale diff --git a/MAKEALL b/MAKEALL index dbed268..a209a4d 100755 --- a/MAKEALL +++ b/MAKEALL @@ -487,6 +487,7 @@ LIST_ARM9=" \ mx1ads \ mx1fs2 \ netstar \ + nmdk8815 \ omap1510inn \ omap1610h2 \ omap1610inn \ diff --git a/Makefile b/Makefile index fd521b6..de6e6ab 100644 --- a/Makefile +++ b/Makefile @@ -2644,6 +2644,17 @@ mx1fs2_config : unconfig netstar_config: unconfig @$(MKCONFIG) $(@:_config=) arm arm925t netstar +nmdk8815_config \ +nmdk8815_onenand_config: unconfig + @ > $(obj)include/config.h + @if [ "$(findstring _onenand, $@)" ] ; then \ + echo "#define CONFIG_BOOT_ONENAND" >> $(obj)include/config.h; \ + $(XECHO) "... configured for OneNand Flash"; \ + else \ + $(XECHO) "... configured for Nand Flash"; \ + fi + @$(MKCONFIG) -a nmdk8815 arm arm926ejs nmdk8815 st nomadik + omap1510inn_config : unconfig @$(MKCONFIG) $(@:_config=) arm arm925t omap1510inn diff --git a/board/st/nmdk8815/Makefile b/board/st/nmdk8815/Makefile new file mode 100644 index 0000000..be9a424 --- /dev/null +++ b/board/st/nmdk8815/Makefile @@ -0,0 +1,55 @@ +# +# (C) Copyright 2000-2004 +# Wolfgang Denk, DENX Software Engineering, wd(a)denx.de. +# +# (C) Copyright 2004 +# ARM Ltd. +# Philippe Robin, <philippe.robin(a)arm.com> +# +# 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.
