![]() At the first login, we use the login root and password 1234 Is the default password. Upon successful connection, we will see an invitation to enter a username and password. We connect to the Orange Pi via the COM port using Putty. In the “Device Manager” we need to look at the COM port number that was assigned to this device. When connected via USB OTG to a computer, Orange Pi is defined as an ELMO GMAS device on one of the COM ports. The standard USB port of a computer can usually give a current of up to 500 mA, so you need to connect the Orange Pi either through a USB port expander with a fairly powerful external power source, Either supply additional power to the Orange Pi via other USB connectors, or through the GPIO comb. At the same time, you need to remember that for Orange Pi you need a power source that can provide a current of 2 A. You can connect the keyboard to the USB connector and watch the signal on the monitor via an HDMI cable (or even through RCA Video out if you prefer). There are several ways to connect to the Orange Pi. We insert the card into the Orange Pi and apply power to it. To communicate with Orange Pi, we need another program. Later we will compare this speed with the write speed to the internal eMMC flash. If several external media are connected, we specify on which media we will record and go to recording.ĭuring the transfer of the operating system, we note that the write speed to the SD card that I had is 12.4 MB / s. To transfer an operating system image to a card, armbian developers recommend using Etcher.Īfter starting Etcher, select the image that we want to record. After installing the system, we will test the speed of exchange with the SD card and internal memory. If the card is slow, the installation will take longer, but then the system will be transferred to the internal memory and everything will work with optimal performance. ![]() We plan to boot from the card once, and then transfer the system to internal memory. But taking into account that eMMC flash (8GB) is installed on Orange Pi Zero +2 H5, the SD card speed class is not important for us. Cards with a large volume usually have a higher speed class. By analogy with the marking of ordinary cards, the speed class of UHS-cards fits into the Latin letter U. Newer cards support the Ultra High Speed interface. The marking of the speed class for conventional cards is a number inscribed in the Latin letter C. A card with this class should provide a minimum write speed of 10 Mb / s. It is recommended that you use a card with a Speed Class of at least 10. We need to write the image to the SD card. In the archive, in addition to the image itself, there is a license file, a file with a PGP signature, and a sha256 checksum file. Ubuntu was created based on Debian and these are very close operating systems. Debian has a reputation as a more stable distribution, while on Ubuntu we have more recent software packages available.
