[beagleboard] DC-DC of TPS65950 getting broken, beagleboard

Hello, I manufactured and produced a board that basically is the same as the beagleboard. 1) I got it working for some hours (configuring linux), and after that it suddenly stopped responding. The TPS65950 was really hot (really,really hot!), the VDD1 module was consuming too much current and

Re: [beagleboard] VBAT voltage value

Thanks for your answer. And is there any special reason for powering VBAT with 4.2V instead of 3.6V? (I am asking this because I designed a board with the BeagleBoard schematics, and after 1 hour working (configuring linux on it through UART), the board stopped responding, the VDD1 dc/dc got

[beagleboard] Re: MMC1: strange voltage values in MMC1 module pins DAT[3-0], WP and CMD

Ok, thanks for your help, I finally got it. My SYS_BOOT configuration was wrong: I inserted also the do not insert resistors. After removing them the card module worked and I was able to boot. The 0.5V is the voltage that you can measure in a pin that has an active pull-down: after fixing the

[beagleboard] MMC1: strange voltage values in MMC1 module pins DAT[3-0], WP and CMD

Hello, I built a board really similar to beagleboard rev4 from scratch. I just added some USB ports and other few changes.(buy the components, manufacture it, design the layers..etc) After some problems I finally got a “40W” in the terminal connected to UART3. I could not boot from SDCard
