U-boot enable not working for Raspberry Pi3

U-boot enable not working for Raspberry Pi3

[Greg Wilson-Lindberg]

I'm working with a Yocto Sumo build provided with Qt's boot2qt system. I'm trying to enable using Das U-boot to load Linux as a first step in trying to enable OSTree updates.

In the meta-raspberrypi documentation is says to set:

RPI_USE_U_BOOT = "1"

to enable u-boot for the raspberrypi. I have set that variable in the top level local.conf file but I don't seem to be getting any changes in the build. Nothing in the cooker log shows building u-boot, and the start up screen doesn't show any u-boot messages.

It appears that I'm missing necessary to turn u-boot on, can anybody shed some light on what is going on?

Hi. I'm working with the U-Boot and RPI3 at the moment as well. I'm 
using warrior revision and not using the
Qt at all though. In my case setting the above variable was enough to 
build the U-Boot and include it in
the final image.

In my case the platform boots into the Linux. I'm having issues with 
weird artifacts and resolution on the HDMI
display, though. I believe this may be related to the U-Boot patching 
DTB to add the
simplefb: 
https://github.com/u-boot/u-boot/blob/master/board/raspberrypi/rpi/rpi.c#L490
while I want to keep using  the brcm fb with userland etc. (proprietary 
stuff).

Could be tha tboot2qt somehow drop your config. Please try tin run
bitbake -e <IMAGE_NAME> | grep ^RPI_USE_U_BOOT to be sure that
variable exists. I used it many times and it works perfectly fine.

Hi Marek,

Thanks for the suggestion, that seems to be the case. What image are you building so I can try that to see what I get?

BR,
Greg

Please don't top post ;). I'm building basic image. I worked few
months ago with bootqt and sometimes it was bit tricky ;). Are you
sure you have this variable set in local.conf?

Here is an excerpt from my local.conf file:

# CONF_VERSION is increased each time build/conf/ changes incompatibly and is used to
# track the version of this file when it was generated. This can safely be ignored if
# this doesn't mean anything to you.
CONF_VERSION = "1"


#
# Custom additions
#

# Additional dtbo's
KERNEL_DEVICETREE_remove = " overlays/mcp2515-can0.dtbo overlays/mcp2515-can1.dtbo"

# Fixes for inclusion of mysql
PACKAGECONFIG_append_pn-qtbase += " sql-mysql"
QT_CONFIG_FLAGS_append_pn-qtbase += " -I /usr/include/mysql"
QT_CONFIG_FLAGS_append_pn-qtbase += " -I ${STAGING_DIR_TARGET}/usr/include/mysql"

RPI_USE_U_BOOT = "1"

# End Custom additions
#

#INHERIT += "rm_work"
INHERIT += "image-buildinfo"
INHERIT += "internal-build"

I copied the line from the meta-raspberrypi documentation so I think it should be formatted correctly. I know the mysql stuff is working correctly.

I tried bitbake -e core-image-minmal and I don't get it being set then either.

Re: U-boot enable not working for Raspberry Pi3

[Greg Wilson-Lindberg]

Hi Marek,

I'm going to top post so you don't have to scroll to the meat of the matter.

I had rebuilt my system because of a failing main hard disk and had lost settings on a number of the programs that I had to re-install and didn't notice. One that has obviously caused me problems is that the editor that I use I keep set to automatically save any changes on loss of focus. I had changed the local.conf file, but I didn't realize that it hadn't written out the changes.

I realized yesterday that the editor wasn't working as I expected and fixed the setting and went on. This morning I rebuilt my yocto system and it rebuilt more than I expected and when I installed it and booted, much to my surprise I realized that u-boot was being executed.

So sorry for the false concern, and thank you for the help and maybe someone will learn something from either my mistake or from your helpful responses.

Best Regards,

Greg Wilson-Lindberg
