Hi,
I am using pins K16, K17, K18, L18, L17, L16 as the MMC1 signals. All of these pins have internal pull downs which are enabled by default. I have provided external pull up resistor on these lines of 10KΩ as suggested in http://processors.wiki.ti.com/index.php/AM335x_Schematic_Checklist#MMC for MMC lines.
My doubt is that because of these internal pull downs whose values can be around 13KΩ providing an extrenal pull up of 10KΩ will act as an voltage divider and hence and the voltage on these pins can reach in unknown state between VIL and VIH. Is it fine?
We can disable or change these internal pull downs only at U-Boot level or kernel. What will happen in between the time duration from power On to U-boot coming up.
Thanks & Regards,
Nikhil
