Hi, I am trying to use IIC4.SDA and IIC4.SCL as gpios in LS1043ARDB. In SCFG_RCWPMUXCR0 register, I have set IIC4_SCL and IIC4_SDA to 001 (i.e., to GPIO_4 and GPIO_4).
Toggling of GPIO_4 (which is GPIO-397) is working fine. But GPIO_4 is not getting toggled. It is always low.
Let me know if i missed anything. Thank you.
we met same questions, we set SCFG_RCWPMUXCR0 register to 0x00000011, which means IIC4_SCL and IIC4_SDA are GPIO4_12 and GPIO4_13, but the GPIO4_12 is not controllable during bootup, looks like was controlled by other function, will be pulled up once POR for about 2seoncds, then be pulled low, and always low.
