CCS: CCS 8.0.0.00016 Linux VM and Uniflash 4.2.2.1692 Linux VM (Ubuntu 17.10)

Hi,

Regarding the Uniflash error message, please check the thread below where some users were having issues in very specific configurations:
e2e.ti.com/.../631006

The CCSv8 error is a bit more informative and may be caused by communication problems between CCS and the JTAG Debug Probe (this may be the same error behind Uniflash's interface as well).

Despite the "Test Connection" button works well, the flash operations are more data intensive and demand more strict timing. Due to the fact a Virtual Machine adds multiple layers of software/drivers between the guest OS and the JTAG debug probes, this tends to impact performance and, sometimes, even block the execution entirely. That may well be your case.

As reported in the page below, some combinations of debug probes and host/guest OSes work, but the multitude of Virtual Machine SW options and the combination of host and guest Operating Systems caused us to refrain from officially supporting CCS (and by extension Uniflash) running on Virtual Machines.

What host OS and Virtual machine SW do you have?
