[U-Boot] LPC2478 - reading/booting from SD card

[Tomislav Puđa]

Hi everyone,

I have problem with LPC2478-STK development board from Olimex (U-boot
1.3.2). There are reported problems with improperly relocated interrupt
vector block. After making suggested changes, mmcinit doesn't freeze
initialization. Could someone give me some explanation why

*lpc-2478-stk # mmcinit*

mmc_init

mci-cid (SD memory card):
  Manufacturer ID: 0x27
  OEM/Application ID: PH
  Product Name: SD01G
  Product Revision: 2.0
  Serial Number: 0xeb215f6a
  Date Code: 2007.11
  sector size = 512 (Bytes), card size = 1019 (MBytes)
  dump csd data: 004f00325f59a3cb
                 ffffff8f8a400028
mmc_block_read: start=0, blkcnt=1.
mmc_block_read: start=0, blkcnt=1.

Return 0 after fat_register_device

What could be wrong? Could someone give me some guidlines where to look for
problem? Everything is OK with SD card, I managed to compile and boot from
usb stick so everything is ok with my compiler.
