[U-Boot-Users] [RFC/PATCH] Add expr command
by Kumar Gala 13 Feb '08

13 Feb '08

Add a simple expr command that will set an env variable as the result of the command. This allows us to do simple math in shell. The following operations are supported: &, |, +, -, *, /. --- I'd like to add this to the default command set in include/config_cmd_default.h but wanted to get feedback on the command before doing that. common/Makefile | 1 + common/cmd_expr.c | 69 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 70 insertions(+), 0 deletions(-) create mode 100644 common/cmd_expr.c diff --git a/common/Makefile b/common/Makefile index 1639109..4f3e711 100644 --- a/common/Makefile +++ b/common/Makefile @@ -54,6 +54,7 @@ COBJS-$(CONFIG_CMD_DOC) += cmd_doc.o COBJS-$(CONFIG_CMD_DTT) += cmd_dtt.o COBJS-y += cmd_eeprom.o COBJS-$(CONFIG_CMD_ELF) += cmd_elf.o +COBJS-$(CONFIG_CMD_EXPR) += cmd_expr.o COBJS-$(CONFIG_CMD_EXT2) += cmd_ext2.o COBJS-$(CONFIG_CMD_FAT) += cmd_fat.o COBJS-y += cmd_fdc.o diff --git a/common/cmd_expr.c b/common/cmd_expr.c new file mode 100644 index 0000000..d9233df --- /dev/null +++ b/common/cmd_expr.c @@ -0,0 +1,69 @@ +/* + * Copyright 2008 Freescale Semiconductor, Inc. + * + * 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-Users] [PATCH 3/3] 8xx: Add OF support to adder87x board
by Bryan O'Donoghue 13 Feb '08

13 Feb '08

Fits in with recent work done in Linux. Adds u-boot support in conjunction with two previous patches to boot a Linux uImage in conjunction with a .dtb generated from the in-tree adder875-uboot.dts in recent PowerPC Linux kernel patches.

[U-Boot-Users] sam9263ek not booting uboot dataflash
by E Robertson 12 Feb '08

12 Feb '08

Hi All, I made some changes to u-boot-1.1.5 atmel patch 1.5 and rebuild uboot. However, after rebuilding it would not run uboot. Has anyone had this problem before? If I rewrite the dataflash with the pre-built uboot image, then it boots so I guess I might be missing something. DataFlash is enabled and all the options looks good so I'm not sure why it's stuct at the RomBoot. I've rebuild both the dataflash bootstrap and uboot several time with no luck so far. Does anyone have any ideas? Thanks.

Greetings. This patch fixes up a compile error that crept with with debug switched on.
