Q

What is the maximum capacity of the SD card (>4GB ~ 32GB) that the ADSP-BF54x
processor's SD controller can support.

A

The ADSP-BF54x supports SDHC and SD 2.0 spec. The driver is capable of
accessing SDHC cards. We have tested against a 4GB card, but they can go up to
32GB at present. High speed mode is supported up to a maximum frequency of
operation of 40MHz. Standard speed is supported up to a maximum frequency of
20MHz max. Please refer to the processor data sheet for more details.
