1For the bootloader, NXP has stablized at SDK2.0 (final release). It is 2suggested to download the prebuilt from NXP downloads and follow the 3release notes for reflashing. 4 5To program the kernel and rootfs created by buildroot into the flash. The 6fast way is to tftp transfer the files via one of the network interfaces. 7Make sure your devkit has ipaddr, netmask, and serverip defined to reach your 8tftp server. Verify bootargs are reasonable (console=ttyS0,115200). 9 10------------------------------------------------------------------------------ 11 12Devkit: T1040RDB 13 14(Assuming the default u-boot env from NXP) 151. Program the DTB to NOR flash 16 17 => 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 18 192. Program the kernel and rootfs to NOR flash 20 21 => tftpboot $loadaddr uImage; protect off 0xe8020000 +$filesize; erase 0xe8020000 +$filesize; cp.b $loadaddr 0xe8020000 $filesize; protect on 0xe8020000 +$filesize; cmp.b $loadaddr 0xe8020000 $filesize 22 => 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 23 243. Booting your new system 25 26 => boot 27 28 You can login with user "root". 29------------------------------------------------------------------------------ 30 31Devkit: T2080 QDS or RDB 32 33(Assuming the default u-boot env from NXP) 341. Netboot the kernel/rootfs/dtb 35 36 => tftp 0x1000000 uImage && tftp 0x2000000 rootfs.cpio.uboot 37 38 RDB => tftp 0x3000000 t2080rdb.dtb 39 or 40 QDS => tftp 0x3000000 t2080qds.dtb 41 422. Booting your new system 43 44 => bootm 0x1000000 0x2000000 0x3000000 45 46 You can login with user "root". 47 483. If flashing is desired, a similar approach to the T1040 can be followed 49 with updated addresses for the flash layout. Example is in the NXP default 50 env. 51------------------------------------------------------------------------------ 52
