TWELITE_Stage installation (macOS)
macOS
環境
We develop in the following environment
macOS 10.14 (Mojave, Intel)
macOS 12.4 (Monterey, Apple Silicon)
Additional installation and warning dialogs.
The download archive is not signed. At runtime, you may receive a security warning as an application downloaded from the Internet.
You may be asked for permission to run from the path where you installed TWELITE_Stage.
You may get an installation dialog for the make utility when executing a build.
The toolchain is code-signed, but if the code signature is not properly authenticated, you may be asked for permission to run each executable in the build toolchain (ba-elf-gcc etc.}).
The above is required to give permission or installation work for the TWELITE_Stage to work.
Reference: Manual installation of the make utility
※ Different OS versions and other factors may require a different procedure.
If an error occurs when executing make on the command line (bash), install XCode.
After installation is complete, type "make" and the following message should appear.
Handling of Serial Port
MONOSTICK and TWELITE-R use FT232 series semiconductors from FTDI (https://www.ftdichip.com). In order to use them, you may need to deal with device drivers.
If the serial port does not appear when you start TWELITE-R, you need to unload (disable) FTDI's driver. See "Reference" below.
Reference: utilities from FTDI, Inc.
This utility suppresses the loading of the OS standard device driver when our MONOSTICK or TWELITE-R is inserted, but it also suppresses it for non-MONOSTICK devices (those with the same USB ID).
Download and use D2xxHelper from https://www.ftdichip.com/Drivers/D2XX.htm. You can find the same in our archive in the TWELITE_Stage/INSTALL folder.
