Here is my uEnv.txt file:


console=ttyO0,115200n8

serverip=192.168.3.1

ipaddr=192.168.3.2

loadaddr=0x82000000

fdtaddr=0x88000000

initrdaddr=0x88080000

loadtftp=echo Booting from network ...;tftpboot ${loadaddr} uImage; tftpboot ${fdtaddr} am335x-boneblack.dtb; tftpboot ${initrdaddr} initramfs

linuxbootargs=setenv bootargs console=${console} root=/dev/ram0 rw initrd=${initrdaddr}

uenvcmd=setenv autoload no; run loadtftp; run linuxbootargs; bootm ${loadaddr} ${initrdaddr} ${fdtaddr}


My question is HOW do I flash this onto the eMMC?  I've tried both the Debian reflashing (adding my uEnv.txt lines into the original uEnv.txt file in the boot folder) and BBB-eMMC reflashers, and have tried using U-Boot's fatload and fatwrite to load from the SD card to the DDR and then write to the eMMC from the DDR. 

What am I missing?  I can't think of anything else.  Which version (Angstrom, Debian, Arago Project) should I be working with? Could you please give me a hint (or two)?
