[U-Boot] dts to dtb generation

[Marco Antônio Possamai]

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.

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. Sorry for the inconvenience.
