Could not upload sketch to Seeeduino Mega

Sorry if the answer is obvious, but I haven’t find a quick answer yet.

I’ve:

  1. just received Seeeduino Mega v1.23 (11/18/2010)
  2. installed x64 VCP driver from ftdichip.com/Drivers/VCP.htm to Win7x64 . Drivers installed successfully, COM5 is available on mine system
  3. connected seeeduino to USB
  4. launched Arduino 0022 IDE, selected board - Arduino Mega 2560 (have tried Arduino Mega (Atmega1280) too), serial port - COM5

When trying to upload example sketch, no any success - RX blinks once a minute, log shows

Binary sketch size: 1540 bytes (of a 258048 byte maximum)
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
…

I’ve also tried to change COM5 baudrate from default to 56700 and 19200, this didn’t help.

Any ideas?

This works! finally

Not sure, what exactly fixed an issue, but it seems that M_RST_A should be turned to A. It was M by default. Also Board Arduino Mega (Atmega1260) should be selected in IDE.
