greeeg 460 Posted April 10, 2012 Share Posted April 10, 2012 I wasn't sure to put this in here or in projects. I've been using SD/MMC cards in my projects as a media for bootloading from. I thought it would be great if the systems I've been working with had USB as removing and replacing SD cards is a timely task when you are developing code. So I designed this board to use with the USB MSP430 devices. It's sole purpose is to connect the USB and breakout all the IO pins of a difficult to breadboard package. But I added some niceties to it, to aid in development. 3 buttons 5 LEDs 1 Micro SD slot. A reset and bootloader button. External power in. Here is the board as I sent it to get fabbed. I only put components on the topside, I like it this way. I copied the USB connections from TI's devboard/datasheets so I hope that all works properly. What do you guys think?

greeeg 460 Posted June 13, 2012 Author Share Posted June 13, 2012 Finally got around to building this. more pictures/eagle v6 files: http://greg.so/projects/0007.html I made a mistake with the USB oscillator. On ICs with an XT2 you MUST connect a high speed crystal in order for the USB to operate. So in the picture you can see I have deadbuged a 8Mhz oscillator onto the X2 pins. I have gotten the builtin USB BSL to work. now I just have to get gcc to compile TI's USB stack. :thumbup: RobG, oPossum and bluehash 3 Quote Link to post Share on other sites
