muliple partions on sd3 based custom baord
we are designed usb sd3 based custom board. we have ported example illustrates the use of the FX3S firmware APIs to implement mass storage class device that allows access to SD/MMC devices connected to SD3 given along wit SDK.
The application partitions the storage device found on storage port into two volumes, and then enumerates them as separate logical units on the USB side
in that example partitions define by
#define CY_FX_SIB_PARTITIONS (2).
.If i have increased to 4 ,it shows 4 partitions . Out of 4 partitions only two partitions data copying possible. If i have clicking other two partitions an message displays " please insert the disk".
kindly suggest how to make multiple partitions.And i need to know how to make on partitions as readable partitions.
