Hello, a while ago Tsvetan from Olimex posted a message that he had problems if the 3.3V supply came up earlier than the 1.8V, another post was excatly the opposite that 3.3V first worked but 1.8V first did not. Our problem is that the hardware we are using either one works. If 3.3V is up first it works, if 1.8V is first same thing. We would like to look into a hardware that shows such a power on sequence problem to make sure we fix it if it needs fixing. Your inputs on this forum as well as e-mail to micro.support@... would be greatly appreciated. Regards, Robert
