hello

 

i have created an own board with a imx6ull processor.

now i have ported uboot for my board.

after compilation ive got a 150kb large .bin file.

i thought that i can download this by jtag into the imx6 internal ram.

unfortunately, the internal ram has only 68kb.

 

i dont have usb ond my board. I also dont have strapped the gpios for the boot process selection.

i only habe boot0 and boot1 pins and uart1–3 and jtag and a sd–card slot at sd port 0.

 

how can i start u–boot?

would you reccomend to burn the efuses?

 

thanks
