Reconfiguring: This configuration uses to the mconf configuration tool to control

in the top-level README.txt file.
Start Delays: If no SD card is present in the slot, or if the network is not
connected, then there will be long start-up delays before you get the NSH
prompt. If I am focused on ENC28J60 debug, I usually disable MMC/SD so that
I don't have to bother with the SD card:

STATUS: The board port is basically functional. Not all features have been
verified. The ENC28J60 network is not yet functional. Networking is
enabled by default in this configuration for testing purposes. To use this

as of this writing. The intent of the granule allocator is to provide
a tool to support platform-specific management of aligned DMA memory.
NOTE: Because each granule is aligned to the granule size and each

size is important: Larger granules will give better performance and

NOTE: Because each granule may be aligned and each allocation is in

Larger granules will give better performance and less overhead but more
losses of memory due to quantization waste. Additional memory waste
can occur from alignment; Of course, heap alignment should no be
used unless (a) you are using the granule allocator to manage DMA memory
and (b) your hardware has specific memory alignment requirements.
The current implementation also restricts the maximum allocation size
to 32 granules. That restriction could be eliminated with some
additional coding effort, but currently requires larger granule
sizes for larger allocations.
Geneneral Usage Example. This is an example using the GCC section
attribute to position a DMA heap in memory (logic in the linker script
would assign the section .dmaheap to the DMA memory.
FAR uint32_t g_dmaheap[DMAHEAP_SIZE] __attribute__((section(.dmaheap)));
The heap is created by calling gran_initialize. Here the granual size
is set to 64 bytes and the alignment to 16 bytes:
GRAN_HANDLE handle = gran_initialize(g_dmaheap, DMAHEAP_SIZE, 6, 4);
Then the GRAN_HANDLE can be used to allocate memory (There is no
GRAN_HANDLE if CONFIG_GRAN_SINGLE=y):
FAR uint8_t *dma_memory = (FAR uint8_t *)gran_alloc(handle, 47);
The actual memory allocates will be 64 byte (wasting 17 bytes) and
will be aligned at least to (1 << log2align).
