[U-Boot] [PATCH resend] at91: Enable slow master clock on meesc board
by Daniel Gorsulowski 25 Nov '09

25 Nov '09

In some cases, we need low speed master clock. So depending on the "mdiv" variable, the processor clock is divided by 2 (default) or 4.

[U-Boot] Unable to launch menuconfig
by Ioannis Kyriakopoulos 25 Nov '09

25 Nov '09

Hi all, I have downloaded the u-boot source and I am able to build it for my target (beagleboard). However, I am not able to launch menuconfig. I know that menuconfig works because I am able to launch it when I am building my Linux kernel. $ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- omap3_beagle_config Configuring for omap3_beagle board... $ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- menuconfig Generating include/autoconf.mk Generating include/autoconf.mk.dep make: *** No rule to make target `menuconfig'. Stop. Any ideas? Thanks in advance. -limp

[U-Boot] [u-boot] [PATCH] imx27: make 26MHz clock input value selectable from config files.
by javier Martin 25 Nov '09

25 Nov '09

Some boards like Freescale imx27-ipcam and Vista Silicon imx27_visstrim_m10 have 25MHz clocks connected to 26MHz input. This patch allows this value to be specified from the board configuration file in the same way as it is done with 32KHz clock. It does not break any existing board since its default value is 26MHz. Tested in imx27lite and imx27_visstrim_m10 board.
