[U-Boot] Undefined results when building highbank board
by Wolfgang Denk 26 Apr '12

26 Apr '12

Dear Rob, arch/arm/cpu/armv7/highbank/config.mk contains this setting: PLATFORM_CPPFLAGS += -march=armv7-a This results in code bueing built with the follwoing compiler options: ... -march=armv5 -march=armv7-a ... This is a bad idea - dependign on tool chain used, this may result in compiler errors ("error: bad value (armv7-a) for -march= switch"), or undefined behaviour, as it is not clear which option is used by the compiler. Can you please provide a fix? Thanks!

[U-Boot] A problem about using the nand command
by li guohu 26 Apr '12

26 Apr '12

Hello, everyone! I find a strange problem when I use the u-boot command. I list the command I used in the u-boot command line as follows. nand erase nand read 0x2000000 0x0 0x800 md 0x2000000 I should see 2K bytes of "0xFF" because I have erase the whole nand flash device. Actually, I find a "0xFD" in one address. Then I try display some other contend of the nand flash. I can also find one "0xFD" in every 2K address space. It is so strange. By the way, I find that the offsets of the addresses of the one "0xFD" from the start of the page are the same. The size of one flash page is 2K bytes. Are the driver of the nand flash in the u-boot wrong? Or are there some other problems?

[U-Boot] PATCH 4/4] patman: Handle searching of patman config
by Vikram Narayanan 26 Apr '12

patman shouts when it couldn't find a $(HOME)/.config/patman file. Also, it couldn't create patch files without the above config file. Handle it in a sane way by creating a new one for the user.
