Factory testing: can we access "tinker" functions via USB for an unclaimed device?

I don’t know who is currently responsible for CLI, but it would be good if the -q switch would also do away with the need for an acknowledgement for something you will know after the first time (or get reminded anyway when you forgot to do what’s needed).
Or add a switch for particularly that (e.g. like many Linux commands offer the -y switch to auto-accept the default response for user-interaction-requests).

@marekparticle, can you tag the person in charge for CLI?

hi sidwarkd,

good to know! i guess there are dependencies. we get a little insight using “particle serial inspect”. see below the system module #2 has a depenency “Bootloader module #0 - version 400”

next virgin p1 i flash i will check not to violate depenencies!

okay, here is a p1 fresh from the particle factory. it has device os version 0.5.3. in this case there is no device os dependency on the bootloader (see below). but i guess if there were it would only explain to load the new bootloader first…

anyhow: i flashed this p1 device-os/system before the bootloader. also works. but have to do an extra “particle usb reset” and “stty -f /dev/cu.usbmodemxxxxxx 14400”

can anyone explain why/how/if/when bootloader after device-os flashing?

We’re closed for the holiday until next week, but upon return I’m sure @m_m would happily take a look! :slight_smile:

it is already implemented, just not documented (as far as i can find): --yes

particle -v flash --serial p1-bootloader\@1.5.2+lto.bin --yes

so no hands:

MackMyra:updates frank$ particle -v flash --serial p1-bootloader\@1.5.2+lto.bin --yes
sending file: p1-bootloader@1.5.2+lto.bin

Flash success!

Flash success!

the only thing open for me is when to flash bootloader after device-os and when it is safe to do the other way (which is faster as it has less steps). anyone any insight?
