Hi ,
I am using OMAP3530 processor 's MMC1 interface to communicate to our wifi-SDIO card. We are facing a problem while configuring the OMAP3530's GPIO 126 (MMC1_DAT4). The default state of this GPIO pin is "Logic low" but we were trying to make it "Logic high" by changing the following registers,
1) CONTROL_PADCONF_MMC1_DAT4 (0x011c) : To configuring line as GPIO input line with pulling up.
2) CONTROL_PBIAS_LITE ( set (3.0V) and reset(1.8V) <-- PBIASLITEVMODE1) : Tried with both setting and resetting the bit PBIASLITEVMODE1, but we were getting logic low at GPIO126. Please let us know what we suppose to do, to get logic high at GPIO126?
Thanks in advance,
Regards,
Ravi.
