先是參考
這一篇
clone git.yoctoproject.org/poky。
clone git,openembedded,org/meta-openembedded
clone github.com/meta-qt5/meta-qt5
clone git.yoctoproject.org/meta-raspberrypi
clone github.com/jumpnow/meta-rpi
作者的 meta-rpi 有提供 conf 下的 local.conf 和 bblayers.conf。
copy 過來,修改一下 bblayers.conf 裡的 path..
bitbake qt5-basic-image 出現 error:
Please use a locale setting which supports utf-8.
Python can't change the filesystem locale after loading so we need a utf-8 when python starts or things won't work.
進入 python, 用 sys.getfilesystemencoding() 看,過然,是 ANSI....
所以 follow
這一篇:
$sudo apt-get install locales
$sudo dpkg-reconfigure locales
$sudo locale-gen en_US.UTF-8
Generating locales
en_US.UTF-8... done
Generation complete.
$sudo update-locale LC_ALL=en_US.UTF-8 LANG=en_US.UTF-8
$export LANG=en_US.UTF-8
然後 build 出現 error:

If this change is expected (e.g. you have upgraded to a new version without updating the checksums) then you can use
these lines within the recipe:
SRC_URI[md5sum] = "c8bf818d14ee260c6d318a8ab037b1b8"
SRC_URI[sha256sum] = "bfeb5471762bef90fb8accb135e9cf4bb08c4a7556df42f31987bd4184f52d10"
Otherwise you should retry the download and/or check with upstream to determine if the file has become corrupted or
otherwise unexpectedly modified.

ERROR: Task (/home/charles-chang/rpi-yocto/meta-raspberrypi/recipes-bsp/bootfiles/bcm2835-bootfiles.bb:do_fetch) failed with exit code '1'
這個是 meta-rpi/recipes-bsp/bootfiles/bcm2835-bootfiles.bbappend 裡的:
RPIFW_DATE = "20170530"
SRCREV = "0f315f88ac91f9be93544bfd757f8d55ca4cf099"
SRC_URI[md5sum] = "2fe42603602158796625989c73e5088b"
SRC_URI[sha256sum] = "79dcd9f47fbae16e9ec80f96a48e4e04c0ee2076ddbb7f73429510d812a8ef89"
RPIFW_SRC_URI = "https://codeload.github.com/raspberrypi/firmware/tar.gz/${SRCREV}"
RPIFW_S = "${WORKDIR}/firmware-${SRCREV}"
PR = "r60"
do_unpack() {
tar -C ${WORKDIR} -xzf ${DL_DIR}/${SRCREV}
}
所以到 github.com/raspberrypi/firmware/,按下
release" 會到每次 release 的 tarball 頁面。
裡面沒有20170530..
最接近的是
https://github.com/raspberrypi/firmware/archive/1.20170515.tar.gz
他的linkname 也不是直接 ${SRCREV}, 而是 1.${RREPFW_DATE}。
反而比較像 meta-raspberrypi/recipes-bsp/bootfiles/../common/firmware.inc:
RPIFW_DATE ?= "20170405"
RPIFW_SRC_URI ?= "https://github.com/raspberrypi/firmware/archive/1.${RPIFW_DATE}.tar.gz"
RPIFW_S ?= "${WORKDIR}/firmware-1.${RPIFW_DATE}"
SRC_URI = "${RPIFW_SRC_URI}"
SRC_URI[md5sum] = "ea82d14a7cd8cfae9b78e00d4e56bc71"
SRC_URI[sha256sum] = "2f4e5bddbac1372590db203002c35cbba3fb9d6172a93c314ee27bf05ae13bff"
PV = "${RPIFW_DATE}"
是 bbappend,所以刪掉這個bootfile.bbappend,重新build 一次...
faile 在其他地方:

看log,看不出fail 在那裡。
bitbake omxplayer
OK
再 bitbake qt5-basic-image
OK
