Detecting when the ST-Link or Target was disconnected

[gustavolaureano]

Hi,

Is there a way to detect, after opening the ST-Link, when the target or the ST-Link was disconnected?

I am coding an application that requires periodic polling of the target's RAM, but also requires to detect when the target or the ST-Link was disconnected (or not yet connected) and reconnect (in hotplug) as soon as it finds the target / stlink again.

During some tests on Linux I could not get any error from stlink_read_mem32() or even stlink_status() when removing the target on the fly.. my solution was to always close and open the stlink when starting the next reading, which works without problems on Linux, but keeps giving me random "denied access" errors on Windows, something related to the libusb.

Thanks!

@gustavolaureano, Hi!

I improved the command status check.
You can try:

@gustavolaureano Have you had the chance to try in the meanwhile?
