For the rookie level of me, the first to compile the kernel, really difficult, a kernel compiler let me toss for a week, poor my Win7 system, because the installation of Ubuntu has to reload, the final computer data are all formatted. Keep a record
Writing the simplest application
#include void Main (int argc, char *argv[]){int i = 0,j = 0;for (i=0;i{printf ("Hello world..............\r\n");for (j=0;j{};}}
and then compile
Arm-linux-gcc-o TST Tst.c-static
Generate TST files and copy them to
follow the wiki tutorial to compile kernel 4.4.y:
My compiler is this one, set first
1, cross_compile=aarch64-linux-gnu-
Configuration file in arch/arm64/configs/
2, make arch=arm64 nanopi3_linux_defconfig
3, Make arch=arm64

This paper analyzes the main NANOPC-T2 platform. NANOPC-T2 is using Samsung's s5p4418 as the main CPU.
When the system is power-up, the s5p4418 maps the Internal ROM code on the 0x3400_0000 to 0x0000_0000 for execution. The code copies data from 0x0000_0200 on the SD card into internal RAM, with a target location of 0xffff_0000 and a data size of 16KB. When the copy is complete, the instruction jumps to 0x

PortalConsider the contribution of the number to the answer at the top of each positionAnd then it's easy to see:If there are n layers, the number of positions I contributes to the answer is C (n-1,i)Then there is the obvious greedy approach:The larger the number, the greater the middle, so that its contribution will be as large as possible.Then consider the C (i,j)Because n is large and the modulus is very smallSo we need to use Lucas ' theorem to find C.C (n,m) = C (n/mo,m/mo) *c (N%MO,M%MO)Wh
