Olimex ARM-USB-OCD-H¶

High-speed 3-IN-1 fast USB ARM/ESP32 JTAG, USB-to-RS232 virtual port and power supply 5VDC device. Official reference can be found here.

macOS contains default FTDIUSBSerialDriver driver which conflicts with debug tools which are based on this chip. FTDI Chip company recommends removing this default driver from a system. Everything should work after system rebooting. See detailed instruction in official application note (Page 16, Section 4: Uninstalling FTDI Drivers on OS X) AN134: FTDI Drivers Installation guide for MAC OS X

Linux:

Please install “udev” rules 99-platformio-udev.rules. If you already installed them before, please check that your rules are up-to-date or repeat steps.
