9.2.4 Special considerations for CM-BF548
There is an issue with BF548 processors with revision number < 0.2 with uClinux due to an
anomaly of the processor. You will get an error explaining the details for those processor
revisions at compile time.
Setting the revision of the processor is done in the kernel configuration menu:
The checks for the BF548 processor revision are done in the following source files:
9.3 Configuration of on-board Components
This section is dedicated to components of the Bluetechnix Evaluation Boards and
Development Boards.
9.3.1 SD/MMC card
To enable SD/MMC card support in uClinux, the following kernel configuration is required:
Furthermore, enable additional file system support in the “File Systems” menu which you
want to use.
9.3.2 USB support (CM-BF527, CM-BF548)
The default setting in the kernel configuration is for USB Host:
