Hi, I'm using an MSP-EXP430F5529LP launchpad to program the watch. but result in tilib: MSP430_OpenDevice: Unknown device (error = 5) error.

there is a detailed result:

I thought it might be a libmsp430.so issue. Can you help me by providing the libmsp430.so file?

commented

I'm using libmsp430.so from the msp430-gcc distribution. Please confirm that that fixes your problem, and then we'll update the documentation before closing this issue.

Hi, there. I run the msp430-gcc installation. And copy the msp430-gcc/bin/libmsp430.so to the /usr/local/lib/. Then problem still exists.

msp430-gcc Version: 9.3.1.2 Release date: 22 Jul 2021

And there is result:

This might be dumb, but this "unknown device (error =5)" is the error I get when I swap SBWTDIO or SBWTCK (or had a poor electric connection to either)

Thank you all!! Finally, I can flash MCU and build the watch now.

The issue about the unknown device (error =5) error could attribute to the fake MCU. When I get a brand new MCU, everything works like a charm.
