Keep console open after target firmware update #18

Open amclain opened 1 year ago

Updating a Nerves target's firmware causes the console to crash when the target reboots.

Regression from #16

amclain commented 1 year ago

It's still not working. The error might be caused by invalid logic levels getting sent to the UART when the target loses power. I don't think it's a specific byte sequence causing the issue.

Take a look at this:

Process.flag(:trap_exit, true)
