i want to change the output of an GPIO pin to an input.
the reason whyis because i want to read an I2C ram without an I2c protokol.
for this i have virtualized the registers of the GPIO7
3026_0000 GPIO data register
3026_0004 GPIO direction register
3026_0008 GPIO pad status register
and in the function i write a 0 to the 9th bit of the GPIO direction register.
but if i read the pad status register or the data register i did not get the right answer.
i read an 0xFFFFFFFF and expected was a 0x55005500.
in this case i think the direction register did not change the direction from output to input.
thanks for your help
