Board : iMX28-evk based
Boot Method : NAND flash (Zentel 128MB)
RAM : DDR2 (Zentel 64MB)
We have made a new board revision named ES_01.
Until the WS_02 board, everything works fine.
But, with this new ES_01 board, there's some problem with USB download. (the USB D+/D- path is not working)
So I tried to download U-boot image directly from RAM to NAND flash.
For the first step, I had attached Lauterbach Trace32 to our ES_01 board successfully.
As for the second step, I had initialized the ES_01 board's DDR2 ram.
And then, I've downloaded u-boot binary to 0x41008000 RAM address and Reset the P.C to 0x41008000.
But, whenever I started the u-boot routine, I got this answer by debug UART.
I am stuck up here.
Any advice would be helpful.
