buildroot preliminary questions on a learning curve
« on: November 18, 2012, 03:14:12 PM »
Hi

1) Is the current image for allwinner hosted here only suitable for 512 Megs of RAM devices?

b) mine is 1 Gig and not yet tested....I haven't got around to doing anything with it yet.

2) If I did go down this pathway,.....using toolchains created with buildroot...... will all my tczs be incompatible with yours?
I realize this question proves I have never cross-compiled but I don't mind exposing my lack of knowledge if it helps others not asking the same silly questions eh?

3) EDIT I was thinking of using  uClibc but

5) uClibc does not provide a database library (libdb).
9) uClibc's locale support is not 100% complete yet.  We are working on it.
extra reasons to above are here http://www.uclibc.org/downloads/Glibc_vs_uClibc_Differences.txt


cheers

  • The posted a10Core image is known to be working on 1GB Hackberry. It also works fine on my 512MB Mele. Many packages can be imported including Xorg. If you are just startiing with allwinner devices, I suggest to learn about script.bin configuration file.

  • A working toolchain can be imported using the import script. It is not a requirement to build your own, but as a knowledge building enddeavor. Cross compiling on x86 works and can be setup to be compatible. Perhaps a search of YouTube for some instructional vidoes.

  • If you choose uclib then you will not be compatible. It would be for your own use and/or worthy as a knowledge building experience.

3) re: uClibc... my poor communication skills. Originally first post said I was looking at it but I am  not now due to the reasons in the editted first post.

I agree this will be my learning curve.  if I brick the device thats my $45 loss. Actually it looks like I can build a generic ARM kernel using buildroot as per image after running.

tce-load -i compiletc ncurses-dev



I am getting exciting just thinking about it.
