Hello everyone,
I use custom board with cyclonev chip.
I use BOOTSEL[2] and BOOTSEL[0] pings as GPIO28, 60 by bi-directional ping.
BOOTSEL[2] and [0] are pulled-up by 10k ohm and I can read ping level(high level) through GPIO_EXT_PORTA register.
But I can't set LOW both ping with GPIO_SWPORTA_DR and DDR registers.
How should I set parameters to any registers ?
Or are thre any restriction to use BOOTSEL pings as GPIO output?
