Bootloader Problem on ZSTAR RD3152 Board

Hi,

I am using two ZSTAR-Kits (RD3152MMA7260Q). On one board, application and bootloader works fine, like described in the reference manual. But on the second board only the application mode is o.k.. If I setup the board for the bootloader mode, Windows driver detects the bootloader correctly, but the hc08sprg.exe from AN2295 fails.
It seems to be a problem with the baud rate, the hc08sprg stops with the following message:

Can't setup serial port (COM8 @ (null))

I have already tried to setup several manual baud rates but it does not work. Even with a terminal program it is impossible to setup a proper connection. The serial protocol stops during the baudrate setup mechanism.
Are there existing different versions of the bootloader or hc08sprg ? Is there a special baud rate I can test?

Thanks,
Martin
