Hi Sudhangathan,

Generally, after making bootable SD card and attach it to the gumstix, I
attach usb cable and select ttyUSB1-> select 115200  on Serial port
terminal, then attach power cable and it starts booting normally.

Yesterday, I shut it down, removed SD card, installed some recipes to the
Image and again attached it back to Gumstix, did the normal procedure,
selected ttyUSB1-> select 115200 , but, this time it did not start booting.
It said "reset your board, could not read kernel" . I removed the power

Now does the message "reset your board, could not read kernel" come all the time..?? That message is from the u-boot.. I assume this message is from the  SD cards' u-boot and not from the NAND flash (if it is present). Something has gone wrong with your uImage file or your rootfs partition on the SD card..!!

Assuming your SD card is OK.. Try formatting your sd card and try again all from copying files again..
cable and attached again, selected ttyUSB1-> 115200 and nothing happens.
Cursor was blinking constantly but nothing appears on the screen. After
waiting for sometime, I again selected ttyUSB0, Nothing happens with just
the cursor blinking constantly.

I attached another SD card and it was the same result. I pressed reset
button 4-5 times, but nothing happened.

Also, post the message when you power up the robovero without SD card..!!
I removed the power cable and did not do it again.
