What is GPIO state of FX3 after it is loaded with slave fifo example(AN65947)? I observe GPIO 50 and 52 are not tristated. I connect these pins to other device. They should be tristated when loaded with this firmware. The default states are tristated, but after booting with slave fifo example,32 bits mode, they are NOT traistated.Why?

Thank you.

Hi,

As mentioned in the thread The GPIO state when FX3 is loading firmware.

Can you please change the GPIO state using CyU3PGpioSetSimpleConfig() to solve your problem?
