All right. 4 GiB sounds like a SDHC card, and not a MMC/SD.
I have no SDHC card here, so I hadn't test it with one. The S3C6410 CPU
built-in ROM code expects a different data layout on SD/MMC and SDHC cards
(due to a bug in this code). So maybe your problem is only related to a wrong
data layout on the card or due to a bug in my SD card writer tool.
You could try the following if you have a Windows PC ('Wine' dues not help):
- download the 'SD card flasher' tool from the FriendlyARM website
- download also the most recent 'superboot' binary from their website
- 'flash' this 'superboot' binary with the 'SD card flasher' tool to your SDHC
cards and test if your Tiny6410 is able to boot from these cards.
Another thing came to my mind: if you are using the u-boot image from our BSP,
its configured for a 128 MiB SDRAM. If your Tiny6410 has 256 MiB of SDRAM, it
will not work.

Re-try with a card <= 2 GiB capacity.

Refer to my info above: SD/MMC and SDHC cards are handled differently in the
built-in ROM, the boot image must be stored in a different way on these types
of cards. Otherwise it will not work.

You know the devil in the details? ;-)

Note this important rule: Everything not tested will not work!!!!!111!!!F1

Please try with a small card with up to 2 GiB.
