Problem witch Using the ISP in 7500/7500p

hi.
I have WIZwiki-W7500P and WIZwiki-W7500 and try using program W7500_ISP(20150820).exe for upload *.bin file in to processor.
but in both case (W7500P and W7500) afther pressing “Open” (serial port):

  • programm W7500_ISP(20150820).exe send 0x55 to com-port
  • board WIZwiki-W7500/WIZwiki-W7500P respond 0x9B 0xFB
  • programm W7500_ISP(20150820).exe send 0x55 to com-port
  • board WIZwiki-W7500/WIZwiki-W7500P respond 0x9B 0xFB
  • programm W7500_ISP(20150820).exe send 0x55 to com-port
  • board WIZwiki-W7500/WIZwiki-W7500P respond 0x9B 0xFB
    and noting!
    what i’m doing no correctly?

I have similar problem: sometimes it’s necessary to press Boot - Reset buttons, then - Open several times to enter ISP mode.
But may be there some problems with your PC port or baud rate.

Tuxxas! Thank you for reply.
That’s right! sometimes it’s necessary to press Boot - Reset buttons.
Thank you
