ADALM2000 - how to unmount the USB mass storage on MacOS and question on HoRNDIS

swcng2001 on Nov 2, 2020

Hello,

I just received the ADALM2000 and connected it to my Mac and installed Scopy.

1. The documentation appears to be quite sparse about the mass storage device that appears when connected. It is labelled as volume "M2k". What I was wondering was what I need to do to unmount the drive before disconnecting the device. If I follow the usual steps to unmount the drive, it will automatically mount itself after a couple of seconds. Can I just pull the plug and assume everything will be alright?

2. I am intending to use the device directly connected to my Mac and have no need to access it over a network so I have not installed HoRNDIS. But the documentation appears to be Pluto specific anyway. Is this correct? I take it then, that there is no other way to connect to the ADALM2000 with a TTY type terminal.

Regards.

Stephen

1. The device is meant to do this. The partition that is mounted is RAM-based so unplugging the device will not break it. Just try not to do it during firmware updates.

2. Pluto and M2K are fundamentally the same from the FPGA back, which is why they share doc. RNDIS is only needed if you want to use the virtual network backend. This isn't necessary to access TTY. Just open putty or screen or something similar and access it like any UART device.

Hello Travis,

Thanks for helping out.

I tried using 'screen /dev/tty.usbmodemxxxxxx 115200' on my Mac and it could not connect. The message I received 'Cannot exec /dev/tty.usbmodemxxxxxx'. Any idea how I can fix this?

Thanks again.

Try running with sudo.

I'm afraid 'sudo' does not help.

Just to make sure you are filling in what xxxxxx means with something actually in /dev?

I only get that error when I put in a bogus path.
