Any one know how to do post in uboot?i am using uboot-toradex.In that when at boot time i have to check the peripherals attached to our board(like usb,uart,ethernet,..).how to do these things in uboot?

please tell me the solution.

You have asked the same question before, and I answered it: http://article.gmane.org/gmane.comp.boot-loaders.u-boot/176741

It makes no sense to ignore answers and ask the same question again - actually it is counter-productive, as it is a really frustrating experience for those who spend their free time trying to help you.

Best regards,
