Feature Request: Hotsync-like functionality in USBDM v4.x

Hello, sometimes working with USB-MULTLINK-BDM i have found very useful the "Hotsync" functionality, that is not present in current CW 6.3 USBDM Debug DLLs, is there any plans to make something similar? I have not jumped into CW10, does it has this functionality embedded in the new IDE?

Dear Carloscuev,

I have considered this but it there are a few issues:

It conflicts with the strategy USBDM uses to ensure it can connect reliably to "difficult" targets. USBDM holds reset & BKGD low when it detects a rising edge on Vcc (depends on which interface of course). This would conflict with the live connection.
The hardware interface is not powered until connected to the target. It is difficult to prevent the buffers driving the lines during power-up. This would require extra components (diodes?)
The BDM connector is not intended for live connection. There is no way of ensurng the connection sequence for the pins.

Some of the above was because I wanted to keep the interface simple as possible. I'll think about it,

bye.

Thanks for the explanation, I understand what if feels when someone wants certain feature that does not comply with planned architecture and/or philosophy of the system. Anyway It would be a nice feature if you decide to do so, Thanks !
