+You'll need to program the files created by buildroot into the flash.
+The fast way is to tftp transfer the files via one of the network interfaces.
+
+Alternatively you can transfer the files via serial console with an Ymodem
+file transfer from your terminal program by using a "loady" command
+from the u-boot prompt instead of the "tftp ..." commands stated below.
+Beware that serial console file transfers are quite slow!
+
+1. Program the DTB to NOR flash
+
+    => tftp $loadaddr p1010rdb-pa.dtb
+    => erase 0xee000000 +$filesize
+    => cp.b $loadaddr 0xee000000 $filesize
+
+2. Program the kernel to NOR flash
+
+    => tftp $loadaddr uImage
+    => erase 0xee080000 +$filesize
+    => cp.b $loadaddr 0xee080000 $filesize
+
+3. Program the root filesystem to NOR flash
+
+    => tftp $loadaddr rootfs.jffs2
+    => erase 0xee800000 0xeff5ffff
+    => cp.b $loadaddr 0xee800000 $filesize
+
+4. Booting your new system
+
+    => setenv norboot 'setenv bootargs root=/dev/mtdblock2 rootfstype=jffs2 console=$consoledev,$baudrate;bootm 0xee080000 - 0xee000000'
+
+    If you want to set this boot option as default:
+
+    => setenv bootcmd 'run norboot'
+    => saveenv
+
+    ...or for a single boot:
+
+    => run norboot
+
+    You can login with user "root".
