Hi,


Meaning to say, you would just let it boot upon power cycle and do not do anything in Uboot environment etc.


Also, want to check are you using the ATF? Arm Trusted Firmware.

Hello.

Yes I don't do anything in Uboot. And actually I use default Uboot cmd from rocketboards page (link is above)

CONFIG_BOOTCOMMAND="load mmc 0:1 \${loadaddr} fpga_bitstream.rbf; bridge disable;fpga load 0 \${loadaddr} \${filesize};bridge enable;run mmcload;run linux_qspi_enable;run rsu_status;run mmcboot"

And yes I use ATF which also was compiled in exactly the same manner as on rocketboards page
