SK-AM64 -not booting from sd card

prasanth S

Hi, i'm trying to boot the am64-sk using sd card with linux default image tisdk-default-image-am64xx-evm.wic.xz .

I have also changed boot partition as mentioned here (On AM64x devices, the bootable SD card image may also have tiboot3-am64x-gp-evm.bin in the boot partition of the SD card image. Renaming tiboot3-am64x-gp-evm.bin to tiboot3.bin and removing/renaming the pre-existing tiboot3.bin of HS-FS type is the only change needed to run the HS-FS SDK on a GP board.)

but,im facing this issue please help me with this.
