Hi,
I install SDK 7.0 for my Sitara Starter Kit board on Ubuntu 12.04 32 bit. Then, I create a SD card. It boots. The thing strange to me is that there are only files
. MLO
. u-boot.img
under boot folder. Below is the echo message:
MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1
*** Error - No Valid Environment Area found

When create the SD card, I select TFTP. But there are no '#' signs when the board boot (As I know for SDK 6.x, it shows '#' sign when downloading kernel from the host). There is no uEnv.txt on the SD card now.
BTW, I random select kernel file: zImage-am335x-evm.bin for TFTP when asked. Is it right for my SK board? Could you tell me where is the kernel loaded now?
Thanks
