I'm developing a new board based on the IMX287.
I'm trying to load the u-boot from the KARO startekit-5 V3 (my design is based in this board) with the provided sb_loader executable and I get the following output:
Looking for a STMP HID device for 10 seconds...
Downloading uboot.bin to device.
. Error(-13) during download.
Does anyone know what I am doing wrong? Any clue about that error?
