For the bootloader, NXP has stablized at SDK2.0 (final release). It is
|
||
|
|
suggested to download the prebuilt from NXP downloads and follow the
|
||
|
|
release notes for reflashing.

To program the kernel and rootfs created by buildroot into the flash. The
|
||
|
|
fast way is to tftp transfer the files via one of the network interfaces.
|
||
|
|
Make sure your devkit has ipaddr and serverip defined to reach your tftp
|
||
|
|
server.
