Title: ARM USB TINY H + FTCSPI.dll
Post by: gaminn on May 30, 2013, 10:30:09 PM
Hello,
I'm trying to communicate with ARM-USB-TINY-H using FTDI's FTCSPI.dll library (v 2.0.0) on Windows 8. However, every call to GetNumHiSpeedDevices or GetNumDevices returns 0 devices (and also return Success).

My ARM-USB-TINY-H is connected to PC and I can use it for debugging in CrossWorks for ARM with no problems.

Any ideas?

Martin

Hey Martin,

The FTDI chip might not work with the FTDI products that require bootloader since we haven't implemented the hardware needed to enter bootloader mode (button or jumper).

There is higher security in Windows 8 and some device interaction/drivers might require the disabling of this "Signature Enfrocement" as shown here: http://www.craftedge.com/tutorials/driver_install_windows8/driver_install_win8.html (http://www.craftedge.com/tutorials/driver_install_windows8/driver_install_win8.html).

Best regards,
Lub/OLIMEX
