Problem with debugging of the L138

Hello!

I use CCS  V. 5.4.0.00091, Sauris SAU510-USB Iso Plus Emulator.

I try to debug empty test project via JTAG on my board with L138. Gel files are set.

And I've got error:

"Error connecting to the target:
(Error -2131 @ 0x0)
Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 5.1.73.0)"

Please, help me.

With the best regards, Artyom.
