Hii,
We have developed our customized board with AM5728 processor.We are using same DDR memory as EVM, the hw changes from EVM are we have used MMC3 for eMMC instead of MMC2, and addition of some serial ports only. NOR Flash we are using 128MB.

After debugging u-boot code i have found that after printing puts("Using default environment\n\n");
it hangs in the function
himport_r(&env_htab, (char *)default_environment, sizeof(default_environment), '\0', flags, 0, NULL).
||
hsearch_r(e, ENTER, &rv, htab, flag)
||
env_flags_init(&htab->table[idx].entry); ------------------ Hangs here, in this function
The same u-boot codes are working fine with EVM. I am unable to proceed further, so please have a look and what can be the reason for these problems?
Thanks & Regards
Ganesh
