Dear Mr.Jason Kridner,
Thank you for your time to read my e-mail.
I found that you are expert on booting Linux on Beaglebone.
I need your help to advise the way to configure to uEnv.txt for U-boot 2015.
I want to boot kernel and Linux from SD card.
Previously, i bought BBB rev A5B it works with uEnv.txt as attached file.
RevA5B U-boot SPL 2013.01.01 (Jun 25 2013)
Then i bought another BBB rev C. It doesn't work with the same uEnv.txt.
RevC U-Boot SPL 2015.01-00001-gb2412df
It can't boot from SDcard.
Could you please help and advise?
Best Regards,
Benjamart
