I'm booting over the network (GbE) from a tftp server. It works, but is IMHO very slow. Is there a faster method for booting over the net?
boot.cmd: dhcp 0x49000000 tftpboot 0x46000000 192.168.1.201:uImage tftpboot 0x49000000 192.168.1.201:u-boot.dtb setenv bootargs console=ttyS0,115200 root=/dev/sda1 rootwait panic=10 rootfstype=ext4 rw ${extra} bootm 0x46000000 - 0x49000000
Btw, in the above script, can I safely replace the addresses with ${kloadaddr} and ${fdtaddr} ? I wonder where these variables get set or obtained from. (I saw these variables somewhere on the net, but there was no initialisation, so I assumed it must be something internal/intrinsic, right?)
And: though my board can output via HDMI, I've no monitor attached, and a serial cable (TTY to USB) I don't have at the moment. Is there another method to get the u-boot output (or log) to be sent to a remote host/log?
Thx
