首先在开启采集程序的时候，遇到这个问题：DM8148 VPSS_GRPX : please open fb1 node first
烧写模式：
NAND boot mode
Switch S1, S1[5:1] ==> 10010 , other pins should be 0 (i.e. OFF). This sets BTM[4:0] in NAND boot mode Switch SW2---->NAND ON
SPI boot mode
Switch S1, S1[5:1] ==> 10110 , other pins should be 0 (i.e. OFF). This sets BTM[4:0] in SPI boot mode Switch SW2---->SPI ON
UART boot mode
Switch S1, S1[5:1] ==> 00001 , other pins should be 0 (i.e. OFF). This sets BTM[4:0] in UART boot mode Switch SW2---->NAND ON
SD boot mode
Switch S1, S1[5:1] ==> 10111 , other pins should be 0 (i.e. OFF). This sets BTM[4:0] in SD boot mode Switch SW2----> Depending on where ENV storage is required enable the appropriate switch.
NOR boot mode
Switch S1, S1[5:1] ==> 10000 , S1[8] ==> 1 , other pins should be 0 (i.e. OFF). This sets BTM[4:0] in NOR boot mode Switch SW2---->NAND OFF, SPI OFF 例子： 我也遇到了这样的问题/** flashing first boot loader into nand **/

board is not booting. Just it get struck giving ccc in minicom window..

Now i switched to SD card boot mode and flashed only first boot loader..
