Hi Jan

I followed the steps as below:

1. entered the build/jerryscript folder and applied the jerryscript.patch with "git apply jerryscript.patch"
2. entered jerryscript/target/mbedos5 and applied the mbed-os.patch with "git apply mbed-os.patch"

cleared the node_modules folder and reran

1. npm install
2. sudo -H gulp --target=realtek_rtl8195am

I get the error as below:
