Does anyone know if BF51x can support MMC4.2 & MMC 4.3 in its RSI controller? Thanks!
BF51x supports MMC 4.2 and MMC 4.3 in software.
Can a MMC 4.3, 8GB card be supported? Do you have code example for software implementation of MMC4.3?
Is it possible to support 4.41 or 4.5?
Most of the new features being added to the MMC specifications can be implemented with software driver updates.
Are there any features in particular of the 4.41 or 4.5 specifications that are of concern or specific interest to you?
Customer just wants to support an 8GB MMC card with BF51x. If BF51x can not support 8GB, how about BF606?
High Capacity SD and MMC devices can be supported on the ADSP-BF51x processors as well as the ADSP-BF60x processors as long as the software driver correctly implements the high capacity card type detection procedure and card capacity calculations via the various device responses and registers. Full details are described in the specifications for the storage device.
Thank you Andy!
I would like to confirm that it should be possible , with mods in software , to support 4.5 devices on a BF 609.
I am currently looking at this output under u-boot with CONFIG_MMC_TRACE turned on
I am new to mmc devices so any clues on how to get started here would help.
I have the 4.3 and 5.1 JEDEC Specs.
