alanmacd opened a new issue #10206: URL: https://github.com/apache/tvm/issues/10206
There are two versions of the nRF5340 development kit, 1.0.0 and 2.0.0. The 1.0.0 DK exposes three COM ports, where COM2 is used to communicate with the device while running tests. The 2.0.0 DK only has two COM ports as can be seen here: ``` $ nrfjprog --com 1050063518 /dev/ttyACM0 VCOM0 1050063518 /dev/ttyACM1 VCOM1 ``` [microtvm_api_server.py always uses VCOM2](https://github.com/apache/tvm/blob/3b2780a4141b5654439c43dfc7c1409f9cb1858c/apps/microtvm/zephyr/template_project/microtvm_api_server.py#L628) which doesn't exist on the 2.0.0 DK. To accommodate this, the USB product ID (PID) can be used to differentiate between the 1.0.0 and 2.0.0 DKs. The PID for 1.0.0 is 1055, while the PID for the 2.0.0 DK is reported as 1051 via lsusb: ``` $ lsusb Bus 005 Device 006: ID 1366:1051 SEGGER J-Link ``` Here are more details from Nordic Semiconductor's site: [nRF5340 DK v2.0.0 COM ports](https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_nrf5340.html#nrf5340-dk-v2-0-0-com-ports) When connected to a computer, the nRF5340 DK v2.0.0 emulates two virtual COM ports. In the default configuration, they are set up as follows: - The first COM port outputs the log from the network core (if available). - The second COM port outputs the log from the application core. [nRF5340 DK v1.0.0 COM ports](https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_nrf5340.html#nrf5340-dk-v1-0-0-com-ports) When connected to a computer, the nRF5340 DK v1.0.0 emulates three virtual COM ports. In the default configuration, they are set up as follows: - The first COM port outputs the log from the network core (if available). - The second (middle) COM port is routed to the P24 connector of the nRF5340 DK. - The third (last) COM port outputs the log from the application core. ### Expected behavior Tests pass while successfully connection to device via VCOM2 ### Actual behavior Tests fail due to inability to connect to device as VCOM2 does not exits. ### Environment Linux Ubuntu 20.04 with nRF5340 v2.0.0 development kit ### Steps to reproduce `pytest test_zephyr.py --zephyr-board=nrf5340dk_nrf5340_cpuapp` -- This is an automated message from the Apache Git Service.
