Subject: [U-Boot] Strange behavior in U-boot fatload command for SD/MMC card
Date: Tue, 2 Oct 2012 15:51:39 +0800 [thread overview]
Message-ID: <009501cda072$c3059010$4910b030$@keyasic.com> (raw)
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,
victor
