[U-Boot] Strange behavior in U-boot fatload command for SD/MMC card

[U-Boot] Strange behavior in U-boot fatload command for SD/MMC card

[victor]

Hi,

 

When using "fatload mmc 0 2e00 u-boot.bin" command, the function handling
that is in common/cmd_fat.c::do_fat_fsload()

 

I put some printf statements in the function:

 

int do_fat_fsload (..)

{

  ..

printf("do_fat_load 1 \n");

        dev = (int)simple_strtoul(argv[2], &ep, 16);

        dev_desc = get_dev(argv[1],dev);

        if (dev_desc == NULL) {

                puts("\n** Invalid boot device **\n");

                return 1;

        }

printf("do_fat_load 2 \n");

  ..

}

 

The output on console is as below. The do_fat_load is hit, but do_fat_load
is not. And the "invalid boot device" is not printed. And it goes to
mmc_init. What mistake that I've made? Thanks.

KA2000# fatload mmc 0 2e00 u-boot.bin

do_fat_load 1

drivers/mmc mmc_init

KA Boot 04240806

Status 20200804

MMC:   ka2000_mmc_init

Thanks,
