Not able to boot beagle bone black from SD card

[sachin malhotra]

Hello,

I am trying to boot TI SDK on beagle bone black, I followed these steps:

1. Partitioning and flashing an image on SD card using this page: http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_create_SD_card_script using Virtual Box VM with Ubuntu 16.04 and TI's - ti-processor-sdk-linux-am335x-evm-03.02.00.05

2. Remove the SD card from PC and insert it in the board, press boot button and plug in the USB to PC to power it on.

No LED blinks except the power LED. 

In the SD card on my windows PC, I can see 2 files  a) MLO  b) u-boot.img

I have booted the board before with Linux, went through with no issues.

What could be the possible reasons here for the board not booting now?
Please let me know if you need any other details

Thanks,
Sachin

Does the power LED blink or does it stay on?

seems to imply that your "b)" should be "u-boot.bin"

In 3.02.00.05 it is u-boot.img so that is correct. 

I'd recommend an FTDI TTL uart cable to debug this so that you can see if uboot is actually being loaded in a terminal.

Are you pressing switch S2 when you insert power to force the boot from SD card?
