[U-Boot] fw_printenv is not working
by mateer 22 Oct '12

22 Oct '12

Hi, when i run fw_printenv , its not working..It shows:- fw_printenv: line 1: syntax error: "(" unexpected error... Let me tell you what i did... 1) i copy the u-boot source code from my colleague and copy in my hard disk. 2) After then i set the environment through commnads. the commands which i run are # make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm distclean # make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm omap3_evm_config # make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm 3) After then i go to /tools/env, where i configure the fw_env.config and then run make command. 4) After ruuning the command i got crc32.c and fw_printenv. 5)i copied the fw_printenv into the SD-Card and insert the card into the OMAP3EVM board. 6) after then when i use the command ./fw_printenv it throws the error fw_printenv: line 1: syntax error: "(" unexpected error.. Can u please help me what i have to do... I think i am doing something wrong... -- View this message in context: http://old.nabble.com/fw_printenv-is-not-working-tp29297562p29297562.html Sent from the Uboot - Users mailing list archive at Nabble.com.

[U-Boot] [PATCH v3 0/18] tegra: Add display driver and LCD support for Seaboard
by Simon Glass 20 Oct '12

20 Oct '12

This series adds support for the Tegra2x's display peripheral. This supports the LCD display on Seaboard and we use this to enable console output in U-Boot on the LCD. Configuration is via the device tree. Proposed bindings are included in this series, taken from pwm bindings that should be in linux-next, a Tegra video binding that might be accepted in devicetree-discuss and a proposed video mode binding posted to dri-devel. While I agree EDID is convenient for machines I would prefer to provide a user-friendly way of selecting LCD settings as well, with EDID more as a fallback and auto-detection when available. To improve performance two optimisations are offered: 1. The LCD frame buffer is cached, with the cache being flushed after each newline sent to putc(), and in a few other situations. This dramatically increases performance (around 10x). This requires a few additions to the ARM cache support. 2. The console supports scrolling in steps of more than 1 line. This speeds up scrolling output considerably, particularly commands like 'printenv' which display a lot of output, and particular when the dcache is off. This requires a new CONFIG and a change to the console_scrollup() function. Changes in v2: - Add new patch to use const in pinmux_config_pingroup/table() - Add nvidia prefix to device tree properties - Align tegra display using new CONFIG_LCD_ALIGNMENT feature - Put the LCD cache flush logic into lcd_putc() instead of lcd_puts() - Update LCD driver to deal with new fdt bindings - Update seaboard LCD definitions for new fdt binding - Use a more generic config CONFIG_LCD_ALIGNMENT for lcd alignment - Use const where possible in funcmux Changes in v3: - Add new commit for pwm binding and node - Add new panel binding to fit with tegra display controller binding - Add probe function to read in fdt parameters in display driver - Add separate call to pwm_init() in board_init() - Adjust LCD driver to use new SOC display driver structures - Bring in proposed tegra display controller binding - Decode fdt node within the pwm driver - Fix tiny bug in mult-line lcd scrolling - Handle a cached frame buffer out of normal U-Boot memory - Introduce concept of a pwm channel, rather than separate peripherals - Move some fdt decode code from LCD driver to SOC display driver - Put the LCD cache flush logic back into lcd_puts() - Remove LPW1 pin which is not needed by display - Remove spurious newline from fdtdec_get_addr() debug output - Rename fdt config structures - Rename pwfm driver to pwm - Separate display driver and LCD driver more in fdt - Tidy up fdtdec_decode_gpios() debug output - Use displaymode binding for fdt - Use new proposed upstream pwm binding - Use new pwm binding from pre-linux-next - Use new upstream proposed LCD definitions Mayuresh Kulkarni (1): tegra: Enable display/lcd support on Seaboard Simon Glass (16): fdt: Tidy debugging, add to fdtdec_get_int/addr() fdt: Add header guard to fdtdec.h tegra: Use const for pinmux_config_pingroup/table() tegra: Add display support to funcmux tegra: fdt: Add pwm binding and node tegra: fdt: Add LCD definitions for Tegra tegra: Add support for PWM tegra: Add LCD driver tegra: Add LCD support to Nvidia boards arm: Add control over cachability of memory regions lcd: Add CONFIG_LCD_ALIGNMENT to select frame buffer alignment lcd: Add support for flushing LCD fb from dcache after update tegra: Align LCD frame buffer to section boundary tegra: Support control of cache settings for LCD tegra: fdt: Add LCD definitions for Seaboard lcd: Add CONSOLE_SCROLL_LINES option to speed console Wei Ni (1): tegra: Add SOC support for display/lcd README | 16 + arch/arm/cpu/armv7/cache_v7.c | 11 + arch/arm/cpu/armv7/tegra2/Makefile | 1 + arch/arm/cpu/armv7/tegra2/display.c | 389 +++++++++++++++++ arch/arm/cpu/armv7/tegra2/funcmux.c | 38 ++ arch/arm/cpu/armv7/tegra2/pinmux.c | 4 +- arch/arm/cpu/armv7/tegra2/pwm.c | 99 +++++ arch/arm/dts/tegra20.dtsi | 96 +++++ arch/arm/include/asm/arch-tegra2/dc.h | 544 ++++++++++++++++++++++++ arch/arm/include/asm/arch-tegra2/display.h | 152 +++++++ arch/arm/include/asm/arch-tegra2/pinmux.h | 4 +- arch/arm/include/asm/arch-tegra2/pwm.h | 75 ++++ arch/arm/include/asm/system.h | 30 ++ arch/arm/lib/cache-cp15.c | 62 +++- board/nvidia/common/board.c | 24 +- board/nvidia/dts/tegra2-seaboard.dts | 32 ++ common/lcd.c | 86 +++- doc/device-tree-bindings/pwm/tegra20-pwm.txt | 18 + doc/device-tree-bindings/video/displaymode.txt | 42 ++ doc/device-tree-bindings/video/tegra20-dc.txt | 89 ++++ drivers/video/Makefile | 1 + drivers/video/tegra.c | 368 ++++++++++++++++ include/configs/seaboard.h | 11 +- include/configs/tegra2-common.h | 3 + include/fdtdec.h | 5 + include/lcd.h | 11 + lib/fdtdec.c | 29 +- 27 files changed, 2199 insertions(+), 41 deletions(-) create mode 100644 arch/arm/cpu/armv7/tegra2/display.c create mode 100644 arch/arm/cpu/armv7/tegra2/pwm.c create mode 100644 arch/arm/include/asm/arch-tegra2/dc.h create mode 100644 arch/arm/include/asm/arch-tegra2/display.h create mode 100644 arch/arm/include/asm/arch-tegra2/pwm.h create mode 100644 doc/device-tree-bindings/pwm/tegra20-pwm.txt create mode 100644 doc/device-tree-bindings/video/displaymode.txt create mode 100644 doc/device-tree-bindings/video/tegra20-dc.txt create mode 100644 drivers/video/tegra.c -- 1.7.7.3

[U-Boot] [PATCH] powerpc/usb: fix bug of CPU halt when missing USB PHY clock
by Shengzhou Liu 18 Oct '12

18 Oct '12

when missing USB PHY clock and issuing "usb start" at u-boot prompt, writing to or_portsc register will cause CPU halt. We should check USBGP[PHY_CLK_VALID] bit at the first time in ehci_hcd_init() to avoid CPU hang in this case.
