Hi all,
I am using a imx6dual processor for our customized board, in that we are using SPI 4 for nor flash, for that i have changed the spi form 0 to 4 in the files mx6q_sabrelite_android.h and mx6q_sabrelite.c , but when i tried to load the u-boot.bin from mfg tool, it stops after the jumping to os and stays in loading u-boot, screen
Note:
Plz check is this configuration is correct and plz tell me if i missed any thing and is it possible to flash u-boot in emmc for a dual processor?
CHANGES I HAVE DONE IN THE FILES
All the mux configuration are correct i have check with our schematic
