raspberry pi5

mkdir -P ~/work/agl

source ~/.bashrc
cd ~/work/agl
repo init -u https://gerrit.automotivelinux.org/gerrit/AGL/AGL-repo

xz -dc agl-ivi-demo-flutter-raspberrypi5.rootfs-20250226013255.wic.xz | sudo dd of=/dev/sdX bs=4M status=progress

なお、buildは一発では通らず、何度か bitbake agl-ivi-demo-flutter すれば通った。何も修正はしていないが。依存関係とかの解決がだめなのかな？？？？それともbuild時にfailするとそのcomponent skipされている？？？

AGL19.90.0(trout) on Rpi5でわかったこと

ivi-demo-flutterでは

• WiFi/BTはつながっていない (scan結果の表示になっていない)
• mouseをつなげばうごく
• 電源ボタンは動く
• 起動は22sec程度でAGL logoがでた (continueまでがでるまでは27secぐらい?)
• profileの保存は動いている
• USB上のmedia再生もできないようだ？
• kernel 6.6.22-v8-16k : armv8で16k page!?
• free

• RaspberryPi5ってば、micro HDMI。。。 (たまたまアダプターあったので助かったが、はまると思うので注意)
