ZedBoard用のlinaro最新版が出来上がったけど、肝心なDeviceTreeであたふたしている。
linaroで作り上げたDTBファイルを見てみると、アドレスとか全然、合っていない。
ん？
って、感じです。
ほかも、ADIのADV7511周辺のDTSファイルを見たけど、ちゃんと書けてないような感じだし。
今日、最新版で立ち上げられるかと思ったけど、どうも難しそう。

ーーーーここまで、起動ログーーーー
ちなみに"ERROR: timer input clock not found"は、drivers/clocksource/cadence_ttc_timer.cが出力している。
ttc=Triple Timer Counter
関数は下記でタイマーの初期化でエラーになった様子だ。
static void __init ttc_timer_init(struct device_node *timer)
今日はここで断念。
