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, netmask, and serverip defined to reach your
|
|
tftp server. Verify bootargs are reasonable (console=ttyS0,115200).

Devkit: T1040RDB
|
|
|
|
(Assuming the default u-boot env from NXP)
|
|
1. Program the DTB to NOR flash
|
|
|
|
=> tftpboot $loadaddr t1040d4rdb.dtb; protect off 0xe8800000 +$filesize; erase 0xe8800000 +$filesize; cp.b $loadaddr 0xe8800000 $filesize; protect on 0xe8800000 +$filesize; cmp.b $loadaddr 0xe8800000 $filesize
|
|
|
|
2. Program the kernel and rootfs to NOR flash
|
|
|
|
=> tftpboot $loadaddr uImage; protect off 0xe8020000 +$filesize; erase 0xe8020000 +$filesize; cp.b $loadaddr 0xe8020000 $filesize; protect on 0xe8020000 +$filesize; cmp.b $loadaddr 0xe8020000 $filesize
|
|
=> tftpboot $loadaddr rootfs.cpio.uboot; protect off 0xe9300000 +$filesize; erase 0xe9300000 +$filesize; cp.b $loadaddr 0xe9300000 $filesize; protect on 0xe9300000 +$filesize; cmp.b $loadaddr 0xe9300000 $filesize
|
|
|
|
3. Booting your new system
|
|
|
|
=> boot
|
|
|
|
You can login with user "root".

|
|
Devkit: T2080 QDS or RDB
|
|
|
|
(Assuming the default u-boot env from NXP)
|
|
1. Netboot the kernel/rootfs/dtb
|
|
|
|
=> tftp 0x1000000 uImage && tftp 0x2000000 rootfs.cpio.uboot
|
|
|
|
RDB => tftp 0x3000000 t2080rdb.dtb
|
|
or
|
|
QDS => tftp 0x3000000 t2080qds.dtb
|
|
|
|
2. Booting your new system
|
|
|
|
=> bootm 0x1000000 0x2000000 0x3000000
|
|
|
|
You can login with user "root".
|
|
|
|
3. If flashing is desired, a similar approach to the T1040 can be followed
|
|
with updated addresses for the flash layout. Example is in the NXP default
|
|
env.
