[U-Boot] [PATCH] ppc: transform init_sequence into a function.
by Joakim Tjernlund 01 Dec '09

01 Dec '09

init_sequence is an array with function pointers. It produces lots of relocation data and it is hard to debug when something fails. Transform it into a function, making it smaller and easier to debug. text data bss dec hex filename 1268 212 0 1480 5c8 lib_ppc/board.org 1224 92 0 1316 524 lib_ppc/board.new Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund(a)transmode.se> --- lib_ppc/board.c | 123 +++++++++++++++++++++++++++++++++--------------------- 1 files changed, 75 insertions(+), 48 deletions(-) diff --git a/lib_ppc/board.c b/lib_ppc/board.c index 765f97a..f0160e6 100644 --- a/lib_ppc/board.c +++ b/lib_ppc/board.c @@ -157,7 +157,6 @@ ulong monitor_flash_len;

[U-Boot] [PATCH]: Nios2/Nios: Remove unneeded linker scripts

The linker scripts in examples/standalone are no longer necessary since STANDALONE_LOAD_ADDR covers the original purpose of the scripts.

[U-Boot] I can not read Linux image from my nand flash
by Peter Pan 01 Dec '09

01 Dec '09

My u-boot version is u-boot-2009-08. In my U-boot, after I entered "nboot 800000 0 0", the following messages shows: Loading from NAND 1GiB 3,3V 8-bit, offset 0x0 Image Name: Linux-2.6.22.sac.rd Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 1045865 Bytes = 1021.4 kB Load Address: 00000000 Entry Point: 00000000 NAND read from offset ffffffff failed 0 ** Read error The image in nand is written in linux 2.6.22 using nandwrite -p /dev/mtd3 uImage This command works fine before. I looked into the source tree, and u-boot should read out the first block in my nand flash to show the information of my image. But, after that, U-boot just think all the following blocks are bad blocks, so it read failed. But when booting linux using nfs with linux image in norflash, there is no bad block shown when linux scan nand for bad blocks. How could this happen? I have no idea right now.
