[Buildroot] Right board to use -- buildroot begniers

[Dinesh Guleria]

Hi,

I am new to buildroot & looking forward to try my hands on creating :--:
linux Kernel
Rfile system
Uboot

For embedded system.

I want to know from your experience which board shall i go for :--
Raspberrypi b version
AT91SAM9260

What i think as something is already existing in buildroot & linux kernel
for support of these two boards, so its good for freshers to learn all
these process on these boards.

Means 32 bit controller whose specs are clearly define so that one can try
hand on creating/configuring memory drivers for sdram or Nand , creating
device drivers , configuring uboot & architecture specific files, porting
linux & rfsystem & uboot made by yourself ?

Katoch

 Problem with Raspberry Pi is that it's rather difficult to understand the SoC,
and its software support is pretty unusual (i.e., far from upstream).

> AT91SAM9260

 That's a SoC, not a board. There are a bunch of devboards with the processor,
but can you still get them? Probably the at91sam9g45m10ek or
atmel_sama5d3_xplained are a better fit.

 The MIPS creator CI20 is also nice. But that's not ARM, of course.

 These things are _not_ something I would advise for an absolute beginner.
Experienced consultants like me plan two to four weeks of full-time work for
porting everything from a devboard to a custom board. So starting from scratch
is definitely an ambitious goal.

Start out with just building and installing the boot loader, kernel and rootfs
for which support already exists. Then maybe you can bump the U-Boot and kernel
version (and contribute patches, of course).

 Anyway, any devboard you can get probably already has U-Boot and kernel
support, otherwise they wouldn't be able to sell it. So unless you're developing
a custom board, re-implementing those from scratch is just duplicate work.

Thanks Arnout, for your reply.

This one is quiet expensive :--
http://www.element14.com/community/docs/DOC-38394/l/evaluation-kit-for-at91sam9g45


It seems to be good bet for beginners  as it is low cost, what do you say ?
http://www.element14.com/community/docs/DOC-65651?CMP=KNC-PS-G-APAC-GEN-MAN
Does it comes with uboot installed ?


Does this buildroot support SAMA5D3 & board in above link ?
http://www.at91.com/linux4sam/bin/view/Linux4SAM/BuildRoot

Please suggest.

Dinesh

 Ah yes I forgot that - I got mine for free :-)

 Check out the linuxgizmos article [1] for a nice overview of low-cost boards.
Some of them have a buildroot defconfig. If you take one which doesn't, you can
develop it yourself and contribute :-)

 That's the atmel_sama5d3_xplained I mentioned. Wow, it is still relatively
expensive...

> Does it comes with uboot installed ?

 I have no idea, but it is fully supported by Buildroot, both for booting from
SD card and booting from flash.


> Does this buildroot support SAMA5D3 & board in above link ? 

 Yes.


> http://www.at91.com/linux4sam/bin/view/Linux4SAM/BuildRoot

 Well, the linux4sam fork is relatively old. In addition, there are some changes
in it that are incorrect. So I'd stick to upstream buildroot :-)

So i will go for atmel_sama5d3_xplained .

With seggers j- link can i flash uboot to the Nand flash of this board ?

Hello,

On Tue, 8 Sep 2015 14:26:31 +0530, Dinesh Guleria wrote:

You don't need that. The Atmel SoCs have a built-in "monitor" that you
can talk to over the USB device port. It requires a tool called SAM-BA.

If you're looking at beginning with the Atmel Xplained, you can follow
the slides/labs at http://free-electrons.com/training/embedded-linux/,
this training is done on this platform, and will teach you how to build
and flash the bootloader, how to build and run a kernel, how to build
your minimal userspace, how to use Buildroot, etc.

Best regards,

Thomas

To flash the bootloader on the sama5d3_xplained board you don't need
any JTAG interface. You just need to remove the NAND CS jumper on the
board and connect on UART with the sam-ba tool.

The labs from the Free Electrons training material have detailed
information on how to do that:

Please suggest will it be worth buying these accessories with following
board :--
http://www.element14.com/community/mobile/mobile-access.jspa#jive-content?content=%2Fapi%2Fcore%2Fv3%2Fcontents%2F625493

This LCD supports 16/24 bit RGB TFT display. So will it be compatible with
this board ?

Actually i mean to say can i use this lcd with gtk & QT libraries or other
linux graphical libraries.

Then i will opt to buy this lcd as its cost is almost sane as board cost.

My colleague Alexandre Belloni has recently updated or added numerous
Atmel defconfigs, and Atmel's plan is to deprecate their Buildroot fork
and to just tell people to use the upstream version (at least that's
what I understood).

But seggers jlink(i.e jtag tool) can be used as an alternative tool to burn
uboot , kernel to NAND of this board right ?

Ok great. So i need only a hardware USB cable for this no external hardware
device right ?

So i can burn uboot, kernel & rfilesystem to the board NAND flash using usb
cable & SAM-BA software tool, right ?

>> you're looking at beginning with the Atmel Xplained, you can follow

Thanks for pointing me to such a wonderful material, it means a lot to me.
Do these two below link point to same board which is mentioned on your site
?

I did not understood this statement on one hand you are saying buildroot
supports Atmel SAM soc & on other hand you are saying support will be
depreciated from next week.

It is deprecated, this will be announced this week.

 The linux4sam fork of buildroot will be deprecated, because the official
buildroot has sufficient support for Atmel chips.

 I hope they'll also update the linux4sam wiki pages to remove all references to
that fork...

 Arnout

[Buildroot] Right board to use -- buildroot begniers

Dinesh,

Could you improve a bit the way you quote text when replying to
e-mails? Your quoting style makes it quite hard to reply.

Yes, probably.

Yes, correct.

Absolutely.

Yes, it is this board.

Atmel used to have a fork of Buildroot with the support for their
boards. Instead of having such a fork, they decided to now support
their boards directly in the official Buildroot. Their fork is
therefore no longer necessary and will be deprecated. Just use the
official Buildroot.

Best regards,

Thomas
