[U-Boot] reducing u-boot.bin size
by Fahd Abidi 13 Dec '08

13 Dec '08

Hello, I am trying to reduce the size of the u-boot.bin file so that it fits into a 256KB promjet. I disabled all the drivers that I didn't need and have just kept the NOR driver but the binary size is still 512KB, it seems to be a hard number coded in somewhere. I would have thought this was the size of the .data section set somewhere in the linker script but it does not appear to be so. Does anyone know where the image size can be altered from?

[U-Boot] problem doing rebase in fresh git.denx.de/u-boot.git clone
by Peter Vollmer 12 Dec '08

12 Dec '08

Hi all, I just tried to do a git bisect in my clone of the u-boot git repo to trace some commits in the past, but I noticed there is a problem doing a rebase in an unchanged fresh clone of git.denx.de/u-boot.git. Thats what I did: ~$ git --version git version 1.5.6.5 ~$ git clone git://git.denx.de/u-boot.git Initialized empty Git repository in /home/pvollmer/u-boot/.git/ remote: Counting objects: 80730, done. remote: Compressing objects: 100% (16904/16904), done. remote: Total 80730 (delta 66116), reused 77805 (delta 63347) Receiving objects: 100% (80730/80730), 26.96 MiB | 5812 KiB/s, done.

To restore the original branch and stop rebasing run "git rebase --abort". ~/uboot$ git rebase --abort I also tried git version 1.6.0.3 with the same result. Any idea what the problem might be ?

[U-Boot] dts to dtb generation
by Marco Antônio Possamai 12 Dec '08

12 Dec '08

Hello, all. I need to get my device-tree blob done, in order to pass it along with the image I've created (bootm command). I'm kind of new on the dtb concept and I'm not sure if I'm doing it right. Have read some stuff about it, though. What I got is that I have to generate a .dtb out of this source file (lite5200b.dts). But I can't get my dtc to work. I've downloaded the latest version (http://jdl.com/software/dtc-latest.tgz) and done the make command, but it points some errors during building. Check the snippet: ... BISON dtc-parser.tab.c DEP dtc-parser.tab.c LEX dtc-lexer.lex.c make: flex: Command not found DEP checks.c DEP srcpos.c DEP treesource.c DEP livetree.c DEP data.c DEP fstree.c DEP flattree.c DEP dtc.c LEX dtc-lexer.lex.c make: flex: Command not found CHK version_gen.h UPD version_gen.h DEP dtc.c LEX dtc-lexer.lex.c make: flex: Command not found CHK version_gen.h CC dtc.o ... And after the 'make install' command it reports the same 'flex: Command not found': LEX dtc-lexer.lex.c make: flex: Command not found CHK version_gen.h I've visited the http://www.embeddedlinuxprimer.com/dtc for the howto steps. Well, I guess it didn't complete the install, the console bashes the dtc as 'not found'. I'm aware there must be some small detail I must be missing in order to get it right, but I'd really appreciate a pointer here. Thanks for the attention. Marco Antônio Possamai Universidade Federal de Santa Catarina P.S: I'm also aware this is possibly not the right mailing list to ask about device-tree compilers... but I haven't found one specific for it.
