Hey all,   my u-boot-1.1.1 hangs while booting, as follow is the message got from the serial: ------------------------------------------------------ U-Boot 1.1.6 (Jan 5 2009 - 18:37:55) DRAM:   8MB Flash:     2MB   ------------------------------------------------------ after some tests by tracing the sequences of the funtions, I found that the u-boot hangs while comming  to this funtion: device_register (&dev),  which is a subfuntion  of drv_system_init (); and I look into device_register(&dev): int device_register (device_t * dev) { ListInsertItem (devlist, dev, LIST_END); return 0; } as follow are two invoid funtions copy from the devices.c. int ListInsertItem (list_t list, void *ptrToItem, int itemPosition) { return ListInsertItems (list, ptrToItem, itemPosition, 1); } int ListInsertItems (list_t list, void *ptrToItems, int firstItemPosition,        int numItemsToInsert) { int numItems = (*list)->numItems;

if (firstItemPosition == numItems + 1)   firstItemPosition = LIST_END; else if (firstItemPosition > numItems)   return 0;

if ((*list)->numItems >= (*list)->listSize) {   if (!ExpandListSpace (list, -numItemsToInsert))    return 0; }

if (firstItemPosition == LIST_START) {   if (numItems == 0) {    /* special case for empty list */    firstItemPosition = LIST_END;   } else {    firstItemPosition = 1;   } }

if (firstItemPosition == LIST_END) { /* add at the end of the list */   if (ptrToItems)    memcpy (ITEMPTR (list, numItems), ptrToItems,      (*list)->itemSize * numItemsToInsert);   else    memset (ITEMPTR (list, numItems), 0,      (*list)->itemSize * numItemsToInsert);

(*list)->numItems += numItemsToInsert; } else {     /* move part of list up to make room for new item */   memmove (ITEMPTR (list, firstItemPosition - 1 + numItemsToInsert),     ITEMPTR (list, firstItemPosition - 1),     (numItems + 1 - firstItemPosition) * (*list)->itemSize);

if (ptrToItems)    memmove (ITEMPTR (list, firstItemPosition - 1), ptrToItems,       (*list)->itemSize * numItemsToInsert);   else    memset (ITEMPTR (list, firstItemPosition - 1), 0,      (*list)->itemSize * numItemsToInsert);

(*list)->numItems += numItemsToInsert; } return 1; }

Most strange thing is sometimes it runs very well. My board is S3C44B0...   Any help is appreciated.   John
