For cyusb 3065，how to use GPIO 17-20 correctly？

[Anonymous]

We are using CYUSB3065-BZXC. In our system, GPIO 17-GPIO25 are used as output. Our problem is: " if " io_cfg.gpioSimpleEn[0]  = 0x3FE0000;, etc. using GPIO17-25"，then  "CyU3PDeviceConfigureIOMatrix (&io_cfg)" return fail;and if"io_cfg.gpioSimpleEn[0]  = 0x3E00000”; Then "CyU3PDeviceConfigureIOMatrix (&io_cfg)" return success; and GPIO21-25 are OK。How to use GPIO 17-20 correctly？

Have a look at CX3 GPIO configuration with CyU3PDeviceConfigureIOMatrix returns ERROR  and GPIO17,19 as simple GPIO output ,cannot be updated (CX3)

As the first post, you could invoke CyU3PDeviceGpioOverride to configure GPIO17-20 to the simple GPIO.
