The bellow is the command line I use. I am using now 4.14.48 compiled as
arm7/ARCH-VEXPRESS . there is no clock tick. The boot hangs in:
....
    while (get_jiffies_64() < waitjiffies)
            udelay(10);

/opt/DS-5_v5.28.1/sw/models/bin/FVP_VE_Cortex-A9x1  -a
/opt/arm7/FVP/FVP_VE_V7/FVP_VE_V7.axf --data
/opt/tlinux-4.14.48/arch/arm/boot/Image@0x80008000 -f
/opt/truly/arm7/fvpbase.conf  --data
/opt/t/linux-4.14.48/arch/arm/boot/dts/vexpress-v2p-ca9.dtb

Any idea ?
