The test 4 = "AddressBus [size] [addr]" without parameter detects alias for any address bit only when: - size = real size of DDR - addr = start of DDR = 0xC0000000 These value must by the default value when parameters are absent. This patch sets bufsize to STM32_DDR_SIZE and get_bufsize() selects the correct value for bufsize when this parameter is absent = full size of the DDDR On EV1 board : DDR> test 4 running at 0xC0000000 length 0x40000000 On DK2 board DDR> test 4 running at 0xC0000000 length 0x20000000 Signed-off-by: Patrick Delaunay <patrick.delaunay at st.com> --- drivers/ram/stm32mp1/stm32mp1_tests.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
