Hi All, No JTAG available and need to understand why Linux 4.8.3 doesn't boot on a x86_64 corei7-64. Hangs at the typical "Starting kernel" location after the last message of the U-boot. The bootcmd is given below.
Do you see the issue when you apply MBA patches . It seems like you use 4.8 kernel but the mba patches are dependent on :
https://marc.info/?l=linux-kernel&m=149125583824700 which is applied on 4.11-rc4.
See a fault FFS and a message indicating the image didn't load after failover. 1) How can I verify if the kernel image was loaded from uboot 2) What is this fault? 3) Has the bootargs or bootcmd changed between 4.1 and 4.8.3? 4) If the boot cmd/arg has changed, what should the boot cmd/arg be for 4.8.3 to boot on x86_64 corei7-64?
