I have designed a Beagleboard rev C4 by myself (manufacturing it). Now I am trying to boot it, but I got a problem: my SD card is always detected as read-only and I can not boot into Linux. I imagine that it is because my MMC1_WP signal is not connected to the right OMAP pin:
Beagleboard has MMC1_WP signal connected to the “ETK_D9/SYS_SECURE_INDICATOR/MMC3_DAT3/HSUSB1_NXT/GPIO_23/MM1_RXDM/HSUSB1_TLL_NXT” pin, but my board has MMC1_WP signal connected to “CSI2_DY1/GPIO_115” pin.
I have been looking into the x-loader and the u-boot source code, but I could not find where to configure the position of MMC1_WP signal in the “CSI2_DY1/GPIO_115” pin.
Does someone know how to do it, what is the code I will need to modify??
Thanks, your help is really appreciated,
