Hi Marek,

Since CONFIG_LOADADDR is not set, the default value of $loadaddr variable is not set in the environment either. Set the default load address to 256 MiB from the start of DRAM.

Yes

I never defined this CONFIG because not yet needed... I alway use the load or boot command with address.

Just to known, you need to have loadaddr for which use case ?

I check the usage in U-Boot code ... And it is the only the default address when the value is not defined in CLI

./cmd/qfw.c:126: env = env_get("loadaddr"); ./cmd/load.c:432: s = env_get("loadaddr"); ./cmd/bootefi.c:369: saddr = env_get("loadaddr"); ./cmd/ini.c:240: argc < 3 ? env_get("loadaddr") : argv[2], NULL, 16); ./cmd/net.c:190: s = env_get("loadaddr"); ./cmd/reiser.c:91: addr_str = env_get("loadaddr"); ./cmd/zfs.c:57: addr_str = env_get("loadaddr"); ./cmd/mvebu/bubt.c:101: addr_str = env_get("loadaddr"); ./fs/fs.c:691: addr_str = env_get("loadaddr"); ./common/board_r.c:467: load_addr = env_get_ulong("loadaddr", 16, load_addr); ./common/update.c:269: env_addr = env_get("loadaddr"); ./common/image.c:563:static int on_loadaddr(const char *name, const char *value, enum env_op op, ./common/image.c:1079: select = (argc == 0) ? env_get("loadaddr") : argv[0];

It is more or less the same usage than:

./include/configs/stm32mp1.h:38:#define CONFIG_SYS_LOAD_ADDR STM32_DDR_BASE

PS: I don't known why we have 2 differents CONFIG : CONFIG_SYS_LOAD_ADDR & CONFIG_LOADADDR

Normally with distro, the others variables for location of each binary are used:

kernel_addr_r=0xc2000000 fdt_addr_r=0xc4000000 scriptaddr=0xc4100000 pxefile_addr_r=0xc4200000 splashimage=0xc4300000 ramdisk_addr_r=0xc4400000

And I don't see reason to don't use the beginning of the DDR for load with address, so I prefer:

- /* - * Needed by "loadb" - */ - #define CONFIG_SYS_LOAD_ADDR STM32_DDR_BASE

+ /* + * default load location -+ */ + #define CONFIG_LOADADDR STM32_DDR_BASE + #define CONFIG_SYS_LOAD_ADDR CONFIG_LOADADDR

But perhaps I miss something...
