Our custom board needs to boot from SD card . Followed the steps from these links
We made necessary changes in Hardware for Internal Boot (Boot_mode-0b10 ) and
for SD4 Selection Boot_CFG2:1 , Boot_CFG2:1.
I cannot see any prints on UART2.
I was using u-boot-imx6-boundary-v2015.07 for bootload code and compiled as explained in above link.
For kernel I was using 3.10.17 Linux-imx6 -Boundary Devices by customizing its device tree for SDIO and other interfaces.
Are these changes sufficient .Do I need to do any changes in Hardware or Software?
Please Suggest some debug methods .
