DM3725: Application Help

Part Number: DM3725
Other Parts Discussed in Thread: DM3730

Hello Team,

Posting on behalf of my customer:

I'm using the DM37x SDK for linux available here:

I'm using the second one, "dvsdk_dm3730-evm_04_03_00_06_setuplinux".

After you download and install that SDK up on a 32-bit Ubuntu 10.04 and by following the instructions in Software Developer's Guide, you can make a bootable SD card.

I have made a 3 partition card like this:
partition 1: Windows_FAT_32
partition 2: Linux
partition 3: Linux

Partition 1 has the MLO (MLO-dm37x-evm), u-boot.bin (u-boot-dm37x-evm.bin) and uImage (uImage-dm37x-evm.bin) files that were copied over from the SDK's psp/prebuilt-images folder.

Partition 2 has the rootfs that was also provided in the SDK (filesystem/dvsdk-dm37x-evm-rootfs.tar.gz) which I had place on the SD by untarring it (ie, I did not simply drag and drop).

After doing that, I put the SD card into my device and tried to boot it. But, after what seems like the MLO is loaded, my UART starts printing weird stuff:

Reading boot sector

Which sort of looks like the baud rate changes? So, I'd like to know what the experts suggest I do- thanks
