Kopycat now is a fully open-source project. In this release we have tried to do our best to run different widespread systems on the emulator. Previous release could run STM32F0xx with FreeRTOS operating system. This time we have added various examples of firmwares for unittesting emulator and to work with different peripheral modules. The most exciting addition is that Kopycat runs Linux on ARM MCU's ARM1176JZ. All these examples are presented in sources and as prebuild modules. A lot of bugs have been fixed in the emulator core and modules.
Added
Core:
- full open-source release
- moved to OpenJDK and version updated to 11.0.x
- register bank system
ARegisterBankNGto simplify configuring processor core (currently only in ARM) - implemented fast wait-for-interrupt processing
Auxiliary:
- NANDGen - NAND modules generator based on standard NAND parameters
- NANDPart - NAND dump loader to partition dump by pages and add ECC in spares
ARM:
- implemented partially MCU ARM1176JZ (enough to run Linux 2.6.x)
- implemented ARMv6 Coprocessor and MMU
- implemented generic timer for ARMv6
- implemented NS16550 UART-controller
- implemented PL190 (VIC) Vector Interrupt Controller
- implemented VirtARM - a virtual ARM-based device
- U-boot and Linux prebuild binaries based on buildroot in example
- implemented DMA-controller in STM32F042
Others:
- different examples to show possible cases how to use Kopycat in projects
- tested development of firmware to STM32 controller using CLion and Kopycat
- Kopycat build plugin to simplify a configuration
build.gradleof new emulator modules - dokkaMultilang build plugin to generate documentation on multiple languages, each language tags with "{EN}"/"{RU}" tokens
Modified
Core:
- embedded Python interpreter fixes, add autodetect of Python version and Jep library path
ARM:
- fixed a lot of bugs in CPU's instructions
- fixed bugs in STM32F042
