Hi，everyone
According to the official development board of BF609, our company according to the required functions made four pieces, but there is a can start uboot, other three pieces can't start, many hardware are examined, only DDR didn't check, whether there is something wrong with the DDR? Or is there is something wrong with the SDRAM?
Three pieces of the development board can not start uboot，can again on the CCES debugging, such as serial port,ethernet, smc0，But also the generated dxe files to generated a LDR file, download to the three board, also can start，I don't know why？
Thanks！
