HI , TI expert
My am4379 board use ti-processor-sdk-linux-rt-am437x-evm-03.03.00.04 sdk. I want to boot it as fast as quickly.So , I using spl os boot function to boot kernel directly.
step:
1 .follow guide :.http://processors.wiki.ti.com/index.php/Linux_Core_U-Boot_User%27s_Guide
1 .put args(dtb) and uImage to 1'st sd partions. uboot console do => setenv boot_os 1 => saveenv
2. Reset the board,but it can not boot up kernel.What is the problem, is sdk do not support spl os boot,or i missing something step?
