[U-Boot-Users] IDE LBA48 support and vsprintf 64bit support

[VanBaren, Gerald (AGRE)]

A much simpler, although not quite as pretty nor as flexible, solution is to print 64 bit integers in two halves.  This only works for hex printouts and the %08X (zero fill with 8 positions) is necessary to make it work.

  printf("This is a hex 64 bit long: %08X%08X", (unsigned int)(data >> 32), (unsigned int)data);
