Problem with flashed GRBL (EKitsZone UNO R3 (ATMEGA 328 / ATMEGA 16U))

Tried to load grbl [github.com]
it's flashing original chip by Xloader, but all I can see is

"Grbl 0.8a
'$' to dump current settings"

I have no responce to any '$' commands ... I've tried many grbl firmwires. Results are the same.
is it possible that I have problem because of ATMEGA 16U or NXP OPAMP?

my board is [www.ebay.com]
"The EKitsZone UNO is 100% compatible with Arduino Uno R3 with some enhancement. It replaced the LM358D with a fast response NXP OPAMP. The new OPAMP is 10 times faster than LM358D in term of dv/dt. The UNO is using the Atmega16U2 as a USB-to-serial converter."

NOBODY CAN HELP?

This is a 3D printing forum. Though some firmwares we use are based on Grbl, they are heavily modified, so few people will have experience with the Grbl firmware. The Atmega processors we use are 644/1024/2560, not the 328. So no one here is likely to have much experience of the chip or board you are using, and whether it has a firmware issue or is faulty. Sorry, I can't help you. I suggest you try contacting EKitsZone where you bought it for support.
