It seems lager board has 2 type of DA9xxx chip, type A, and type B. We don't know which chip your / my board has. My *current* Lager board has no issue on cold / warm boot. Magnus has my previous Lager board, so I can't try it today. I think my current board and previous board have different type of chip. Magnus will bring me my previous board tomorrow, so I will check it, and try your solution. Best regards --- Kuninori Morimoto
