Your v9 patchs have two problems: Problem 1: I have run your v9 patchs with Travis CI today, but it still FAIL. Please check about the failure items as below: https://travis-ci.org/github/rickchen36/u-boot-riscv/builds/678854283 Problem 2: BTW, it also fail to boot smp kernel when I verify with ae350_rv64_defconfig on AE350 board. Please check about the fail booting log: Linux version 4.17.0-00253-g49136e10bcb2 (sqa@atcsqa07) (gcc version 7.3.0 (2019-04-06_nds64le-linux-glibc-v5_experimental)) #1 SMP PREEMPT Sat Apr 6 23:41:49 CST 2019 bootconsole [early0] enabled Initial ramdisk at: 0x (ptrval) (13665712 bytes) Zone ranges: DMA32 [mem 0x0000000000200000-0x000000003fffffff] Normal empty Movable zone start for each node Early memory node ranges node 0: [mem 0x0000000000200000-0x000000003fffffff] Initmem setup node 0 [mem 0x0000000000200000-0x000000003fffffff] software IO TLB [mem 0x3b1f8000-0x3f1f8000] (64MB) mapped at [ (ptrval)- (ptrval)] elf_platform is rv64i2p0m2p0a2p0c2p0xv5-0p0 compatible privileged spec version 1.10 percpu: Embedded 16 pages/cpu @ (ptrval) s28184 r8192 d29160 u65536 Built 1 zonelists, mobility grouping on.
