[Luo Zhenhua-B19537] I verified the u-boot build for p4080ds(e500v2) with binutils-2.23.2, the build passed. I'd like some run-time testing too please :) Thanks! [Luo Zhenhua-B19537] I did sanity test for the u-boot on p4080ds, it works normally. The log files are attached. Best Regards, Zhenhua > Tom
