# Regulart Meeting (2020.3.22)

* Problem in Last Week: root password?
* in official doc: xilinx

## Run program

* compile: using arm-linux-gcc-linaro(compiler) on host(my PC)
* execute: on pynq-z2 board (pynq-z2 default Linux)
* prog: xvc-server-sw (debug mode)


## Progress tree for

* hw: *top.tcl -> output xvc_server.xsa*
* sw: *xvc-server.c* -> compile to *bin* and run on the pynq-z2 with Linux
* OS

  * FSBL <---/                   \
                                 <- BOOT.BIN-----\

  * etc. of linux

FSBL: First-Stage-Boot-Loader

* This boot sequence(ARM) is very different from what we know about x86
* Device Tree is not vailed on x86 target, only for ARM or SPARC or PowerPC
* Note: Modern x86 PCs (~2005) apply UEFI to boot and handle firmware
