You are right! I jumper the wrong pins. Finally...I should post the jumper picture at the beginning. Sorry for bring trouble for you guys. I actually looked at the pin map of this picture, and followed the SV1 side before. <http://gumstix.8.n6.nabble.com/file/n4966616/QQ%E6%88%AA%E5%9B%BE20130125144558.jpg> Now the spike loopback test works! Thank you for your nice reply!!! BTW, could you tell me the steps to boot the u-boot from the mmc. To try boot from the mmc, I actually erase the u-boot.bin in the nand on one board. But the board still tries to load u-boot.bin from the nand. So it cannot boot and hang at: *u-boot.bin not found or blank nand contents - attempting searial boot... ## Ready for binary (kermit) download to 0x80008000 at 115200...* -- View this message in context: http://gumstix.8.n6.nabble.com/SPI-problem-on-Overo-tp4966514p4966616.html Sent from the Gumstix mailing list archive at Nabble.com. |
