[Buildroot] [PATCH v2 0/9] configs: defconfigs for Atmel boards

[Alexandre Belloni]

Hi,

This series updates and adds defconfigs for the recent(ish) atmel boards. They
use Atmel's u-boot and kernel tree and are meant to be flashed on the NAND
flash.

It also provides a flahing helper to ease the flashing of the board and
includes documentation on how to do so.

Changes in v2:
 - Add flashing helper and instructions
 - Update the existing xplained readme
 - Use commit ids instead of branch names
 - Include ubi image generation in the defconfig

Alexandre Belloni (9):
  configs: update at91sam9g45m10ek defconfig
  configs: add defconfig for Atmel at91sam9rlek
  configs: add defconfig for Atmel at91sam9x5ek
  configs: add defconfig for Atmel sama5d3xek
  configs: add defconfig for Atmel sama5d4ek
  configs: add defconfig for Atmel sama5d4 Xplained Ultra
  configs: add defconfig for Atmel sama5d3 Xplained
  atmel: add a flashing helper and documentation
  configs: rename atmel_xplained_defconfig

+Flashing the NAND using SAM-BA
+==============================
+
+This document explains how to flash a basic Buildroot system on various
+Atmel boards. Additional details can
+also be found on the Linux4SAM website, in particular here:
+http://www.at91.com/linux4sam/bin/view/Linux4SAM/GettingStarted
+
+This guide covers the following configurations:
+ - at91sam9g45m10ek_defconfig
+ - at91sam9rlek_defconfig
+ - at91sam9x5ek_defconfig (at91sam9g15, at91sam9g25, at91sam9x25,
+   at91sam9g35 and at91sam9x35)
+ - atmel_sama5d3xek_defconfig (sama5d31, sama5d33, sama5d34, sama5d35,
+   sama5d36)
+ - atmel_sama5d3_xplained_defconfig
+ - atmel_sama5d4ek_defconfig
+ - atmel_sama5d4_xplained_defconfig
+
+These configurations will use AT91Bootstrap, u-boot and a linux kernel from
+the git trees maintained by Atmel. They also build u-boot SPL when
+available, it can replace AT91Bootstrap.

+"RomBOOT" should appear on your console (this should be ttyUSBx or ttyACMx)
+
+Now locate the USB sam-ba interface it should be ttyACMx, usually ttyACM0
+dmesg on your machine should give:
+usb 1-2.1.4: New USB device found, idVendor=03eb, idProduct=6124
+usb 1-2.1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0
+cdc_acm 1-2.1.4:1.0: ttyACM0: USB ACM device
+
+Look for idVendor=03eb, idProduct=6124, this is the interface you want to use.
+
+You can then flash the board using the provided flasher.sh script in board/atmel:
+
+board/atmel/flasher.sh <builddir_path> <interface> <board>
+
+For example:
+board/atmel/flasher.sh /tmp/atmel_sama5d3_xplained/ /dev/ttyACM0 sama5d3_xplained
+
+Reboot, the system should boot up to the buildroot login invite.

[Buildroot] [PATCH v2 9/9] configs: rename atmel_xplained_defconfig

[Alexandre Belloni]

For consistency, rename atmel_xplained_defconfig to
atmel_sama5d3_xplained_mmc_defconfig as this configuration supports
booting the sama5d3 Xplained with an MMC card (as opposed to the NAND
flash).

[Buildroot] [PATCH v2 8/9] atmel: add a flashing helper and documentation

Since you didn't mention out of tree build in this document, I think 
'./output/' would be better as first argument example. Adding a comment on out 
of tree build would be nice, though.

Yeah, I thought about that and that is why I used ./output in usage().

I'll switch to:

"
For example, for an out of tree build made in
/tmp/atmel_sama5d3_xplained/ for the sama5d3 Xplained, you would use:
board/atmel/flasher.sh /tmp/atmel_sama5d3_xplained/ /dev/ttyACM0 sama5d3_xplained

You also need to ensure that the kernel headers used for the toolchain
are of the same version or older than the kernel you're
building/running.

So, something like:

BR2_KERNEL_HEADERS_VERSION=y
BR2_DEFAULT_KERNEL_VERSION="3.18"
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_3_18=y

And ditto for all your other defconfigs.

Thanks!

Hum, at some point we'll have to think about using $(wildcard ...) or
something like that to allow wildcards in this option. But since
there's only one user for now, and it's not very common to have
gazillions of DTs for a given board, it's probably not worth the effort.

This file should really be called readme.txt and not nandflash.txt. I
know it doesn't cover anything but NAND flash for the moment, but
readme.txt is really the convention we use for all platforms.

Otherwise, great job. I really like the tutorial covering all the
evaluation boards, with details on connecting the debug UART and the
USB device cable.

Thanks!
