I dont have the uboot sauce.Also i did ask for the gpl code via their form and they putted that in the site that u sanded.I tried ask for the uboot sauce via the live support chat but i got nothing back.Maybe i should use the form again?(linksys dont have the uboot sauce in the gpl tarball of other rotuer as well. i guess it is the time for fsf to suit linksys twice? (See https://en.wikipedia.org/wiki/Free_Software_Foundation%2C_Inc._v._Cisco_Systems%2C_Inc.) ) Also Other linksys ipq5018 based rotuer is capable of booting arm64.maybe i could rip the uboot from those rotuer and flash it to ea9350 v3 but i dont have another linksys ipq5018 based rotuer.
