Hi, I used to use GPIOs 146 and 147 for receiving trigger timestamps. Now I want to use GPIO 127 & 128 and it doesn't work at all. For this purpose I'm using Dave Hylands gpio-event driver. In order to configure my GPIOs, I'm directly rewriting the PADCONF registers. However that's not possible. No matter which value I choose in the PADCONF registers, the values are both stuck to 0x100 and so the pins stay in pinmuxing mode 0. Looks like those PADCONF registers are somehow locked. Please don't tell me u-boot does that, I'm afraid to recompile u-boot for this "little issue" :/ Any help or pointers are welcome. Cheers Phil |
