Other Parts Discussed in Thread: DM3730
I am trying too boot our custom board with DM3730 Processor. I U-Boot boots fine from the SD Card powered by VMMC1 and hands over to the kernel. However somewhere during the Kernel booting process, VMMC1 is turned and it can therefore not mount the root filesystem on the SD Card. Here are a couple of printout from the kenel

The Kernel hangs at that last line and does not get past it. I know it's because there is no longer the 3.0V that powers the MMC interface. How can i get the Kernel to not tamper with VMMC1? Both the XLoader and U-Boot are configured to use VMMC1 from the the power management IC but it seems like the Kernel is expecting me to have an external LDO and is instructing the power management IC to turn off VMMC1. I have looked in the configuration file but i cannot seem to see what config option i need to turn on/off for this to happen. I have tried both DVSDK 4.1 & 4.2 and they both have the same kernel. Any help will be very much appreciated.
