-# RISC-V Phone
-
-The goal of the this project is to develop a privacy enhanced, simple and fully featured mobile phone.
-
-**Technical specs**:
-
-  - CPU: SiFive Freedom E310 (FE310-G002) microcontroller
-  - WiFi/BT: Espressif ESP32
-  - Graphics: BT815 Display/Touch Controller
-  - Baseband: Mini PCIe module (SIMCom SIM7600X or Quectel EC-25)
-  - Audio: MAX98357A Class D amplifier / ICS-43434 MEMS Microphone
-  - Accelerometer: LSM9DS1 - gyro, accel, magnetometer
-  - Haptic driver: DRV2605L
-  - NXP i.MX8M System-on-Module daughterboard
-
-##1. Building
-
-Follow theese instructions to build both FE310 and ESP32 firmware.
-
-###1.1 Install prerequisites
-
-You will need the following software available on your machine:
-
-  - git
-  - GNU Make
-  - RISC-V GNU Toolchain
-  - RISC-V OpenOCD
-  - ESP-IDF from Espressif
-
-Binary RISC-V GNU Toolchain and OpenOCD are available from SiFive at [https://github.com/sifive/freedom-tools/releases](https://github.com/sifive/freedom-tools/releases)
-
-Download and unpack the archives for your platform and export `RISCV_PATH` and `RISCV_OPENOCD_PATH` variables:
-
-```
-export RISCV_PATH=/path/to/riscv64-gcc
-export RISCV_OPENOCD_PATH=/path/to/riscv-openocd
-```
-
-To install ESP-IDF follow instructions from [ESP-IDF Programming Guide](https://docs.espressif.com/projects/esp-idf/en/stable/get-started/index.html#installation-step-by-step). Install version 4.2 or later.
-
-###1.2 Obtain source
-
-This repository can be cloned by running the following command:
-
-```
-git clone git://majstor.org/rvPhone.git
-```
-
-Repository contains following directories:
-
-  - `hw/rvPhone`: KiCad v5 project that contains schematics and board layout
-  - `fw/fe310`: Firmware for Freedom FE310-G002 SoC
-  - `fw/esp32`: Firmware for Espressif ESP32 SoC
-
-###1.3 Build
-To build firmware for FE310 run follwing commands:
-
-```
-cd <path to repository>/fw/fe310
-make
-cd test
-make upload
-```
-
-To build firmware for ESP32 run following commands:
-
-```
-cd <path to repository>/fw/esp32
-make menuconfig
-make
-make flash
-```
-
-In `make menuconfig`, please make sure that `Enable PPP support` is selected under `Component config -> LWIP` menu and that `Notify Phase Callback`, `PAP Support` and `CHAP Support` are selected under PPP menu.
