[Buildroot] [PATCH 1/1] configs/rzboard_v2L_defconfig: new defconfig

[kilian.zinnecker--- via buildroot]

From: Kilian Zinnecker <kilian.zinnecker@mail.de>

This patch adds support for the AVNET RZBoard V2L.

The board support creates a bootable sd card image. The board is
shipped with a u-boot inside its eMMC. The board support uses this
u-boot and does not build and deploy a u-boot onto the sd card.
Instead the sd card only contains a uEnv.txt, a kernel image and
the rootfs.

+RZBoard V2L
+===========
+https://www.avnet.com/wps/portal/us/products/avnet-boards/avnet-board-families/rzboard-v2l/
+
+This board support creates a bootable sd card image for the AVNET RZBoard V2L.
+This board is shipped with a u-boot inside its eMMC. This board support uses
+that u-boot and only puts uEnv.txt, kernel image and rootfs onto the sd card.
+
+Build:
+======
+  $ make rzboard_v2l_defconfig
+  $ make
+
+Files created in output directory
+=================================
+
+output/images
+.
+├── Image
+├── boot.vfat
+├── rootfs.ext2
+├── rootfs.ext4
+├── rootfs.tar
+├── rzboard.dtb
+├── sdcard.img
+└── uEnv.txt
+
+Creating bootable SD card:
+==========================
+
+Simply invoke (as root)
+
+sudo dd if=output/images/sdcard.img of=/dev/sdX && sync
+
+Where X is your SD card device.
+
+Booting:
+========
+
+Configure board for sd card boot:
+---------------------------------
+Set the 'BOOT1' switch (next to the audio jack) to '1' (away from 'ON') in
+order to let the board boot kernel and rootfs from SD card.
+
+Serial console:
+---------------
+The RZBoard V2L has a 4-pin header "J19" right next to the micro USB. Its
+layout can be seen in the Quick-Start Guide, or the Hardware User Guide,
+obtainable from:
+https://www.avnet.com/wps/portal/us/products/avnet-boards/avnet-board-families/rzboard-v2l/
+
+The uart pins are as follows (from left to right - orientation according to the
+board's labeling):
+
+pin 1: n/a  (most away from the board's corner)
+pin 2: tx
+pin 3: rx
+pin 4: gnd  (nearest to the board's corner)
+
+Baudrate for this board is 115200.
+
+Power-Up:
+---------
+Plug in a suitable USB-C power supply and press the button 'S1' (next to the
+USB-C port) for 2 seconds until the LED goes on.
+
+Login:
+------
+Enter 'root' as login user, and the prompt is ready.

Can you please add the board's URL like:
https://embedded.avnet.com/product/rzboard-v2l/
?

You can remove the size if it's not strictly necessary, it will be
64M anyway because rootfs.ext2 is defined in board's defconfig,

Do we actually need DTB_OVERLAY_SUPPORT in this defconfig? I mean, are 
there any overlay dtbo files that are dynamically applied?
If not please drop the line above

Here you also need:
BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL=y

Wait for V2 patch then.

Thank you!

Thanks, I have applied to master, after renaming to
avnet_rzboard_v2l_defconfig, and taking into account the feedback from
Giulio.

However, I find it not so nice that we don't build a fully bootable
image that includes U-Boot. Could you work on this and submit a
follow-up patch?

There is a DIP switch on the board that allows to boot from SD, see
page 15 of the board hardware manual;

Best regards,

Thomas

Hello Thomas, Giulio, all,

Thanks Giulio for reviewing my patch and your feedback!

Yes, I agree and would prefer a bootable image, containing a uboot built by 
buildroot as part of the boot chain, too. I therefore tried to run uboot from 
SD card at first (using the information from the hardware manual you refered 
to), but I was not successful. Hence I asked the author of a hackster.io 
article about the RZBoard V2L boot [1], whether he could help me. He told me, 
that he asked the Avnet BSP team, and "they confirmed there is no official 
support for storing bootloader files on micro sd". This matches his article, 
listing only eMMC and QSPI as possible locations for the bootloader.

However, maybe this information is incomplete and there is in fact a way to 
run uboot from SD card, which I just was not able to get working. I can try to 
reach out to the Avnet support myself. And even if there is no way to do that, 
I can try to adjust the board support to build uboot, figure out how to flash 
uboot to the eMMC and document that in the readme. May take me some time 
though at the moment. 

Best regards,
Kilian

Thanks for the additional details. Indeed in this case, the best option
would be to have our defconfig build a uboot that works on QSPI, or
eMMC, and provide the instructions on how to reflash the QSPI or eMMC.

Thanks a lot!
