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 Reviewed-by: Patrice Chotard Signed-off-by: Patrick Delaunay --- diff --git a/drivers/ram/stm32mp1/stm32mp1_tests.c b/drivers/ram/stm32mp1/stm32mp1_tests.c index fec9fd010e..a2a69da9a3 100644 --- a/drivers/ram/stm32mp1/stm32mp1_tests.c +++ b/drivers/ram/stm32mp1/stm32mp1_tests.c @@ -442,7 +442,7 @@ static enum test_result test_addressbus(struct stm32mp1_ddrctl *ctl, u32 bufsize; u32 error; - if (get_bufsize(string, argc, argv, 0, &bufsize, 4 * 1024, 4)) + if (get_bufsize(string, argc, argv, 0, &bufsize, STM32_DDR_SIZE, 4)) return TEST_ERROR; if (!is_power_of_2(bufsize)) { sprintf(string, "size 0x%x is not a power of 2", @@ -452,6 +452,7 @@ static enum test_result test_addressbus(struct stm32mp1_ddrctl *ctl, if (get_addr(string, argc, argv, 1, &addr)) return TEST_ERROR; + printf("running at 0x%08x length 0x%x\n", addr, bufsize); error = (u32)addressbus((u32 *)addr, bufsize); if (error) { sprintf(string, "0x%x: error for address 0x%x",
