Hi again,
1. Can you please test if it works with a SDHC card?
2. I do not have Windows PC that why I´m using the BSP packages.
Is there another way to solve the problem?
3. My tiny6410 has 256 MiB SDRAM.
Can I try to use the u-boot_256MB privided by FriedlyARM in combination
with
the BSP?
Does your u-boot provides some additional features?
4. I will try to use and test with a 2GB SDHC card.
5. can you please give some advices on how I can generate a 256MB BSP
Bootloader?
Thanks for reply.
Regards.
