[U-Boot] [PATCH] Generic udelay() with watchdog support
by Ingo van Lil 05 Dec '09

05 Dec '09

According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay().

[U-Boot] [PATCH v2 00/10] i386 Relocation
by Graeme Russ 05 Dec '09

05 Dec '09

Version 2 of previously submitted patch set. The changes are minor (added missed hiding of irq_common_entry in patch 8 and added #define CONFIG_RELOC_FIXUP_WORKS and setting GD_FLG_RELOC in patch 10) This patch series implements full relocation support for the i386 port of U-Boot. The first 5 patches came about due to my toolchain upgrade (to gcc 4.4.1 and binutils 2.19) (patch 4 id really just a quick tidy-up) Patch 6 is a standalone bug-fix to resolve a start-up race condition Patch 7 sets up the i386 interupt handling to be relocation friendly Patches 8 and 9 are a relocation setup patch - no functionality change By the end of patch 9, the i386 port is still non-relocatable Patch 10 is the actual Relocation Patch itself Relocation is achieved by utilising the -pie ld command line option and minimal boot-up processing of the resulting .rel.dyn section. By not using gcc's -fpie flag, the overhead of .got and the call/pop in each function entry is avoided - This prevents bloat of .text and .got and avoids the performance penalty of GOT lookups This relocation scheme is possibly usable on many other arches Many thanks to Joakim Tjernlund and Bill Campbell for their invaluable assistance and references.

[U-Boot] [PATCH] EXT2FS: fix inode size for ext2fs rev#0
by Michael Brandt 05 Dec '09

05 Dec '09

From: Michael Brandt <Michael.Brandt(a)emsyso.de> extfs.c assumes that there is always a valid inode_size field in the superblock. But this is not true for ext2fs rev 0. Such ext2fs images are for instance generated by genext2fs. Symptoms on ARM machines are messages like: "raise: Signal # 8 caught" This fix checks for rev 0 and uses then 128 bytes as inode size.

Hi, I am using 9G20 and set eccmode NAND_ECC_NONE in u-boot, but when I try to write some data from memory into flash with u-boot interface, it failed. (sam-ba can not read this page back from nand flash, it says a bad block). but I use NAND_ECC_SOFT, it is successful. why? anyone can give some help? Thanks in advance. -- View this message in context: http://old.nabble.com/NAND_ECC_NONE-in-u-boot-question-tp26642489p26642489.… Sent from the Uboot - Users mailing list archive at Nabble.com.

[U-Boot] [PATCH] add block write function to spartan3 slave serial load
by Wolfgang Wegner 04 Dec '09

04 Dec '09

Using seperate function calls for each bit-bang of slave serial load can be painfully slow. This patch adds the possibility to supply a block write function that loads the complete block of data in one call (like it can already be done with Altera FPGAs). On an MCF5373L (240 MHz) loading an XC3S4000 this reduces the load time from around 15 seconds to around 3 seconds Signed-off-by: Wolfgang Wegner <w.wegner(a)astro-kom.de> --- drivers/fpga/spartan3.c | 54 +++++++++++++++++++++++++--------------------- include/spartan3.h | 1 + include/xilinx.h | 1 + 3 files changed, 31 insertions(+), 25 deletions(-) diff --git a/drivers/fpga/spartan3.c b/drivers/fpga/spartan3.c index 0fe3041..7a89b56 100644 --- a/drivers/fpga/spartan3.c +++ b/drivers/fpga/spartan3.c @@ -385,34 +385,38 @@ static int Spartan3_ss_load (Xilinx_desc * desc, void *buf, size_t bsize) } while ((*fn->init) (cookie)); /* Load the data */ - while (bytecount < bsize) { - - /* Xilinx detects an error if INIT goes low (active) - while DONE is low (inactive) */ - if ((*fn->done) (cookie) == 0 && (*fn->init) (cookie)) { - puts ("** CRC error during FPGA load.\n"); - return (FPGA_FAIL); - } - val = data [bytecount ++]; - i = 8; - do { - /* Deassert the clock */ - (*fn->clk) (FALSE, TRUE, cookie); - CONFIG_FPGA_DELAY (); - /* Write data */ - (*fn->wr) ((val & 0x80), TRUE, cookie); - CONFIG_FPGA_DELAY (); - /* Assert the clock */ - (*fn->clk) (TRUE, TRUE, cookie); - CONFIG_FPGA_DELAY (); - val <<= 1; - i --; - } while (i > 0); + if(*fn->bwr) + (*fn->bwr) (data, bsize, TRUE, cookie); + else { + while (bytecount < bsize) { + + /* Xilinx detects an error if INIT goes low (active) + while DONE is low (inactive) */ + if ((*fn->done) (cookie) == 0 && (*fn->init) (cookie)) { + puts ("** CRC error during FPGA load.\n"); + return (FPGA_FAIL); + } + val = data [bytecount ++]; + i = 8; + do { + /* Deassert the clock */ + (*fn->clk) (FALSE, TRUE, cookie); + CONFIG_FPGA_DELAY (); + /* Write data */ + (*fn->wr) ((val & 0x80), TRUE, cookie); + CONFIG_FPGA_DELAY (); + /* Assert the clock */ + (*fn->clk) (TRUE, TRUE, cookie); + CONFIG_FPGA_DELAY (); + val <<= 1; + i --; + } while (i > 0); #ifdef CONFIG_SYS_FPGA_PROG_FEEDBACK - if (bytecount % (bsize / 40) == 0) - putc ('.'); /* let them know we are alive */ + if (bytecount % (bsize / 40) == 0) + putc ('.'); /* let them know we are alive */ #endif + } } CONFIG_FPGA_DELAY (); diff --git a/include/spartan3.h b/include/spartan3.h index 30b1c2d..d5a589d 100644 --- a/include/spartan3.h +++ b/include/spartan3.h @@ -57,6 +57,7 @@ typedef struct { Xilinx_done_fn done; Xilinx_wr_fn wr; Xilinx_post_fn post; + Xilinx_bwr_fn bwr; /* block write function */ } Xilinx_Spartan3_Slave_Serial_fns; /* Device Image Sizes diff --git a/include/xilinx.h b/include/xilinx.h index d0799bc..2cb2e5b 100644 --- a/include/xilinx.h +++ b/include/xilinx.h @@ -100,5 +100,6 @@ typedef int (*Xilinx_busy_fn)( int cookie ); typedef int (*Xilinx_abort_fn)( int cookie ); typedef int (*Xilinx_pre_fn)( int cookie ); typedef int (*Xilinx_post_fn)( int cookie ); +typedef int (*Xilinx_bwr_fn)( void *buf, size_t len, int flush, int cookie ); #endif /* _XILINX_H_ */ -- 1.5.6.5

[U-Boot] [PATCH v2] makefiles: fixes for building build tools
by Scott Wood 04 Dec '09

04 Dec '09

Currently, some of the tools instead set CC to be HOSTCC in order to re-use some pattern rules -- but this fails when the user overrides CC on the make command line. Also, the HOSTCFLAGS in tools/Makefile are currently not being used because config.mk overwrites them. This patch adds static pattern rules for files that have been requested to be built with the native compiler using $(HOSTSRCS) and $(HOSTOBJS), and converts the tools to use them. It restores easylogo to using the host compiler, which was broken by commit 38d299c2db81bd889c601b5dfc12c4e83ef83333 (if this was an intentional change, please let me know -- but it seems to be a build tool). It restores -pedantic and the special flags for darwin and cygwin that were requested in tools/makefile (but keeps the flags added by config.mk) -- hopefully someone can test this on those platforms. It no longer conditionalizes -pedantic on not being darwin; it wasn't clear that that was intentional, and unless there's a real problem it's just inviting people to contribute non-pedantic patches to those files (I'm not a fan of -pedantic personally, but if it's on for one platform it should be on for all). HOST_LDFLAGS is renamed HOSTLDFLAGS for consistency with the previous HOST_CFLAGS to HOSTCFLAGS rename. A new HOSTCFLAGS_NOPED is made available for those files which currently cannot be built with -pedantic, and replaces the old FIT_CFLAGS. imls now uses the cross compiler properly, rather than by trying to reconstruct CC using the typoed $(CROSS_COMPILER). envcrc.c is now dependency-processed unconditionally -- previously it would be built without being on (HOST)SRCS if CONFIG_ENV_IS_EMBEDDED was not selected. Signed-off-by: Scott Wood <scottwood(a)freescale.com> --- since v1: HOSTCFLAGS becomes HOSTCFLAGS_NOPED PEDCFLAGS becomes HOSTCFLAGS rebased to next branch I added some missing HOSTLDFLAGS references, but I decided against doing HOSTCOMPILE/HOSTLINK because of the number of combinations -- compile, compile noped, link, and link noped (because we could be compiling at the same time), and questions about whether we'll necessarily want HOSTCFLAGS if we're purely linking, whether LDFLAGS are harmful if purely compiling (and thus we could get rid of HOSTLINK), etc. Plus, we don't have anything analogous for the non-host case. config.mk | 34 ++++++++++++- rules.mk | 13 ++++- tools/Makefile | 121 +++++++++++++--------------------------------- tools/easylogo/Makefile | 9 ++- tools/gdb/Makefile | 15 ++---- tools/imls/Makefile | 29 ++++------- 6 files changed, 98 insertions(+), 123 deletions(-) diff --git a/config.mk b/config.mk index 8cfd60c..cb1c4af 100644 --- a/config.mk +++ b/config.mk @@ -46,13 +46,41 @@ PLATFORM_LDFLAGS = ######################################################################### +HOSTCFLAGS = -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer \ + $(HOSTCPPFLAGS) +HOSTSTRIP = strip + +# +# Mac OS X / Darwin's C preprocessor is Apple specific.

[U-Boot] [PATCH] usb: write command for RAW partition.
by Mahavir Jain 03 Dec '09

03 Dec '09

This patch implements write support to usb device with raw partition. It will be useful for filesystem write support to usb device from u-boot in future. Tested with writing kernel image to raw usb disk & booting with usb read command into ram. [Note: run usb part to get info about start sector & number of sectors on a partition for usb write operation.] Signed-off-by: Mahavir Jain <mjain(a)marvell.com> --- common/cmd_usb.c | 24 ++++++++++++ common/usb_storage.c | 99 ++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 123 insertions(+), 0 deletions(-) diff --git a/common/cmd_usb.c b/common/cmd_usb.c index 7b8ee6b..1acb6fc 100644 --- a/common/cmd_usb.c +++ b/common/cmd_usb.c @@ -642,6 +642,28 @@ int do_usb(cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) return 1; } } + if (strcmp(argv[1], "write") == 0) { + if (usb_stor_curr_dev < 0) { + printf("no current device selected\n"); + return 1; + } + if (argc == 5) { + unsigned long addr = simple_strtoul(argv[2], NULL, 16); + unsigned long blk = simple_strtoul(argv[3], NULL, 16); + unsigned long cnt = simple_strtoul(argv[4], NULL, 16); + unsigned long n; + printf("\nUSB write: device %d block # %ld, count %ld" + " ...

[U-Boot] Ttftp problem while retrieving a file
by Abraham Arce 03 Dec '09

03 Dec '09

Hi, I am using ks8851snl ethernet driver from beagleboard + micrel. I am able to dhcp whatever file size but tftp only works the first time once board has been turned on. the dhcp comamnd will execute TftpStart() after getting all data from the server but not sure what specific initialization is different in both. I'll appreciate any comments... Bes Regards Abraham
