we have got two same version c293 custom board, board 1 can work normally, when connecting USB tap through jtag, run the command "source c:/c293_board_recover/c29x_ddr.tcl" in ccs, the u-boot can show up, like attchment board1_ccs.txt.
but another board 2, if we run the same command, the u-boot can not show up,like attchment board2_ccs.txt. it seem write some bytes into the DDR, but not all of it. like
writing 65536 bytes to 11000000 ...000011000000: 27051956 552d426f 6f742032 3031332e '..VU-Boot 2013.
