Claim to be board revision C, consistently -- we had the revision in the wrong part of SCC_AID. * SCC_ID bits [15:4] should be 0x505, not decimal 505 Signed-off-by: Peter Maydell --- hw/arm/mps2-tz.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/hw/arm/mps2-tz.c b/hw/arm/mps2-tz.c index cedf605e20e..cb252d8ebcc 100644 --- a/hw/arm/mps2-tz.c +++ b/hw/arm/mps2-tz.c @@ -192,7 +192,7 @@ static MemoryRegion *make_scc(MPS2TZMachineState *mms, void *opaque, sccdev = DEVICE(scc); qdev_set_parent_bus(sccdev, sysbus_get_default()); qdev_prop_set_uint32(sccdev, "scc-cfg4", 0x2); - qdev_prop_set_uint32(sccdev, "scc-aid", 0x02000008); + qdev_prop_set_uint32(sccdev, "scc-aid", 0x00200008); qdev_prop_set_uint32(sccdev, "scc-id", mmc->scc_id); object_property_set_bool(OBJECT(scc), true, "realized", &error_fatal); return sysbus_mmio_get_region(SYS_BUS_DEVICE(sccdev), 0); @@ -604,7 +604,7 @@ static void mps2tz_an505_class_init(ObjectClass *oc, void *data) mc->desc = "ARM MPS2 with AN505 FPGA image for Cortex-M33"; mmc->fpga_type = FPGA_AN505; mc->default_cpu_type = ARM_CPU_TYPE_NAME("cortex-m33"); - mmc->scc_id = 0x41040000 | (505 << 4); + mmc->scc_id = 0x41040000 | (0x505 << 4); } static const TypeInfo mps2tz_info = { -- 2.18.0
