File transfer via ethernet during u-boot stage.

Hi BBB community,
I’m setting up my development environment and need to transfer a kernel image from my laptop to the Beagle Bone after u-boot.

Could someone guide me on the best way to do this?

I no longer support this mode, due to change in later u-boot versions, we might be able to bring it back.. Basicly have a file (uEnv.txt) with this:

##Rename as: uEnv.txt to boot via nfs

##https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt

##SERVER: sudo apt-get install tftpd-hpa
##SERVER:
##SERVER: zImage boot:
##SERVER: TFTP_DIRECTORY defined in /etc/default/tftpd-hpa
##SERVER: zImage/*.dtb need to be located here:
##SERVER: TFTP_DIRECTORY/zImage
##SERVER: TFTP_DIRECTORY/dtbs/*.dtb
##SERVER:
##SERVER: uname_r boot:
##SERVER: TFTP_DIRECTORY defined in /etc/default/tftpd-hpa
##SERVER: Change TFTP_DIRECTORY to /NFSEXPORT/boot
##SERVER: TFTP_DIRECTORY/vmlinuz-\${uname_r}
##SERVER: TFTP_DIRECTORY/dtbs/\${uname_r}/*.dtb

##client_ip needs to be set for u-boot to try booting via nfs

client_ip=192.168.1.101

#u-boot defaults: uncomment and override where needed

#server_ip=192.168.1.100
#gw_ip=192.168.1.1
#netmask=255.255.255.0
#hostname=
#device=eth0
#autoconf=off
#root_dir=/home/userid/targetNFS
#nfs_options=,vers=3
#nfsrootfstype=ext4 rootwait fixrtc

##use uname_r= only if TFTP SERVER is setup for uname_r boot:
#uname_r=

I think it works up to this branch: GitHub - beagleboard/u-boot at v2019.04-bbb.io-am335x

Otherwise, yeah hands off! :wink:
