 ## How it works
-Explain how your project works
-it works it works
+After implementing a KianV uLinux TT06, I felt like implementing a KianV bare
+metal edition, which is an RV32E RISC-V32 SoC. This SoC is equipped with a
+UART, qspi memory controller (psram/flash), a generic SPI interface, and a sigma-delta emulator for playing audio
+files. In the firmware folder, the kernelboot.c and crt0.S files display all
+hardware registers and their initialization in the code.
 
 ## How to test
-Explain how to use your project
-Explain how to use your project
+First, one must build the toolchain for an RV32E, as you can see here:
+```
+sudo apt-get update
+sudo apt-get install autoconf automake autotools-dev curl python3 libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev
+git clone --recursive https://github.com/riscv/riscv-gnu-toolchain.git
+cd riscv-gnu-toolchain
+./configure --prefix=/opt/riscv32e --with-arch=rv32e --with-abi=ilp32e
+make
+export PATH=/opt/riscv32e/bin:$PATH
+```
+The following hardware addresses are given:
+```
+#define LSR_DR 0x01
+#define LSR_TEMT 0x40
+#define LSR_THRE 0x20
+#define PWM_ADDR (IO_BASE + 0x14)
+#define REG_DIV (IO_BASE + 0x10)
+#define SPI_DIV (IO_BASE + 0x500010)
+#define UART_LSR (IO_BASE + 0x5)
+#define UART_RX (IO_BASE)
+#define UART_TX (IO_BASE)
+```
+The use of the registers can be determined from the C, linker script and assembly program.
+The CPU starts to execute the instruction stored in the NOR Flash at an offset of 1MiB.
+When the chip comes into my hands, I will provide demos that I test on the
+chip, including audio playback with appropriate documentation.
+
 
 ## External hardware
-List external hardware used in your project (e.g. PMOD, LED display, etc), if any
-List external hardware used in your project (e.g. PMOD, LED display, etc), if any
+It's very important to use the PMOD Flash + PSRAM. We only use 8MB of PSRAM
+address space.
