DM365 and sfh_DM36x.exe communication problem

Hi.

I have a custom board based on DM365 processor and try to flash it using sfh_DM36x.exe utility. But the programm shows only "Waiting for the DM36x..." message.

I tried to flash DM365EVM board using this utility and everything was ok.

When I connect to my custom board with Tera Term, I see "BOOTME" output. In Tera Term I also try to send manualy a command "    ACK<NULL>67B0019C386801000000" (as sfh_DM36x.exe did in successfull session with DM365EVM). And I receive "BEGIN" string from processor. So, connection is ok and programms can communicate with DM365.

But when I start sfh_DM36x.exe it is just "Waiting for the DM36x...". I use serial port monitor programm and can't see any "BOOTME" output from DM365. It looks like serial port is opened with bad settings.

When I open serial port connection with Tera Term or Putty, I see "BOOTME" output from DM365 in serial port monitor programm.

When DM365EVM board is connected to PC and I run sfh_DM36x.exe, I also can see "BOOTME" and everything else in session.

Thanks in advance.
