    • Processor SDK Linux for AM335X 08_02_00_24
    • Custom board running 
    • AM3352BZCZ SoC, 512MB Samsung K4B4G1646B DDR3 RAM, 2GB Micron MTFC4GACAJCN eMMC. 

    After power up, uboot console message appears once, takes around 50 seconds to display the machine details and proceed with booting.

    Machine is booting from microSD card inserted in the micrSD card slot on the custom board.

    Please let me know if more details are required.

    Hello,
    One option is to run "grabserial" or similar tool to have an idea on boot time profiling on your board?
    50 seconds to get u-boot prompt looks long...
