+If you bought modules with NAND flash 1GB and more then you need to compile a different version of u-boot, because this type of NAND has a different physical structure. The commands should be issued:
+<code>
+make ARCH=arm CROSS_COMPILE=${CC} distclean
+make ARCH=arm CROSS_COMPILE=${CC} am335x_nand4k_defconfig
+make ARCH=arm CROSS_COMPILE=${CC}

+===== Debian 8.0.0 (Wheezy) Root File System =====
 This file system is very small and can be installed to the NAND flash on uSomIQ. It is not that small like Angstrom minimal distribution (~20M), but will require around 75M on the flash. However it is a real Debian system with apt-get utility installed.
