Versioning is important but I think that the most important reason to keep the
docs in the repositories is because we have a visible, manageable process to
update critical documents via PRs. For example,changes to the coding standard
need careful review and approval.Sent from Samsung tablet.
I don't know anything about the DMA, but you should not call calloc() from
within the OS. That does not work in all configurations.Instead include
nuttx/kmalloc,h and call kmm_malloc(). If you want aligned memory, call
kmm_memalgn().Sent from Samsung tablet.
