*Hi,*
*I know there is many topics about NFS and TFTP. But I still could not find why my board is not booting via NFS.. Have been trying couple of days many many different ways now and I have no clue where it goes wrong and its getting frustrating now.* *I believe there might be something wrong with my uEnv.txt...* *I think TFTP boot works fine and loads zImage and .dtb. Could anybody point me in right direction? Any help or tip for better information source is appreciated.* *I have used this tutorial to set up TFTP and NFS servers: http://linuxkernel51.blogspot.com/2015/08/boot-beaglebone-black-with-nfs.html <http://linuxkernel51.blogspot.com/2015/08/boot-beaglebone-black-with-nfs.html>* *uEnv.txt and kernel log attached.* U-Boot 2018.01-geac41e26ac (Nov 30 2018 - 12:20:11 +0000) CPU : AM335X-GP rev 2.1 Model: TI AM335x BeagleBone Black DRAM: 512 MiB NAND: 0 MiB MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 *** Warning - bad CRC, using default environment <ethaddr> not set.
