Dear Engineers:
I don't know how to set/modify the uboot environment variables so that the DM3730 can boot from TFTP/NFS. The SDK is dvsdk_dm3730-evm_04_03_00_06_setuplinux. Can you help me solve the problem. Thanks!
My uboot environment variables show as follow:
bootcmd=if mmc init; then if run loadbootscript; then run bootscript; else if run loaduimage; then run mmcboot; else run nandboot; fi; fi; else run nandboot; fi
