Hi @ all, 10 Month ago, i bought a overo earth and summit-Board. It runs pretty good. Since a few days the kernel don't boot. After the message "Uncompressing Linux... done, booting the kernel.", the board begins at the start again.

Hi Manfred, How are you powering your Summit? - Neil |

Hi Neil, thank you for reply. I powered my Summit with a professional power supply with 5V and 2A. If i turn on power the blue and green LED on Overo-Earth board turn on. After "Uncompressing Linux... done, booting the kernel." the blue LED on overo-board turns off and the red LED on summit-Board turn on. On Putty, the Board start again and the red LED on summit turn off and the blue LED on Overo-Board turn on. The green LED on overo-board lights always. I suspect your suspicion, that probably the power supply does not provide the necessary performance, but i have tried a few other power supplies. i have measured a voltage on the summit-board of 4.94V and the power-supply show a current of 200mA. At the "restart" the voltage fall down to 4.88V.

Hi @ all, it is unbelievable! I have few professionals Powersupplies. And the overo+summit isn't booting with them. I'm desperate at this problem. *A big thank you to Neil.* He brought me to thinking about the power supply. Just, I bought in a supermarket a cheap universal power supply for 15 euro. And i see! the overo+summit boots perfect. I can not believe it still. it is to fight hair. I spent days with this problem now and a little cheap power solves it. I am writing this response may help others to be able to.
