Other Parts Discussed in Thread: UNIFLASH

Tool/software:

Hi，

I am starting with SBL.And I booted Linux from eMMC. In order to use Falcon boot, just re-build the Linux app image and flash it. Use the command:

cd ${SDK_INSTALL_PATH}/tools/boot/linuxAppimageGen
  make -s BOARD=am62x-sk all FALCON_MODE=1

The resulting product is 

linux.appimage.hs_fs

the size is 19M.(Only 800k without falcon mode)

I use the following command to flash.

sudo dd if=linux.appimage.hs_fs of=/dev/mmcblk0boot0 seek=36864

And I got an error while flashing.

So,Is falcon Mode used correctly?How to solve this problem?

Best Regards,

Gangqiang

    Yes, the falcon boot image is a large file. That is correct.

    You can try flashing using uart uniflash, but that will take a while to get flashed.

    You can also copy the file into boot partition of SD card and flash it using mtd command.
