On 9263 the sram is huge so you can build barebox as first stage I add this a long time ago on usb_a9263_bootstrap_defconfig or other (all the EK). This will build a barebox that can load you image from multiple source in a sequence and then use a std barebox To switch to DT you will have to import the DT I did for the kernel and replace the hw i2c by a i2c gpio as the i2c IP on at91 has a lot of quirks and for barebox it will not make sense to port it Best Regards, J. _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
