[U-Boot] dts to dtb generation
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 Hi Marco, You are missing the flex package, and thus the flex command, on your system. Flex is a lexical parser (classic name lex). You didn't say what your host's distribution is. If it is debian, you need to install the flex package. RH/SuSE may name their package differently (probably not). http://packages.debian.org/search?keywords=flexsearchon=namessuite=allsection=all Best regards, gvb ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Hi Marco, BISON dtc-parser.tab.c DEP dtc-parser.tab.c LEX dtc-lexer.lex.c make: flex: Command not found Actually, I do not know, how an error message could be more clear than that. Obviously your Linux installation is missing the GNU lexical scanner generator flex. It should be trivial to install that package for the distro that you use.
