First, when the collection program is enabled, this problem occurs: dm8148 vpss_grpx: Please open Fb1 node first

Burning mode:

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 modeSwitch 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 modeSwitch 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 modeSwitch 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 modeSwitch SW2----> Depending on where ENV storage is required enable the appropriate switch.

Nor Boot Mode

Switch S1, S1 [5] ==> 10000, S1 [8] ==> 1, other pins shoshould be 0 (I. e. off ). this sets BTM [] In nor boot modeswitch sw2 ----> NAND off, SPI off example: I also encountered this problem

Board is not booting. Just it get struck giving CCC in minicom window ..
Ccccccccccccccccc (here I get struck)
Now I switched to SD card Boot Mode and flashed only first boot loader ..
