[jira] [Commented] (MYNEWT-186) move sbrk to MCU

    [ https://issues.apache.org/jira/browse/MYNEWT-186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15176964#comment-15176964 ] 

Marko Kiiskila commented on MYNEWT-186:
---------------------------------------

BSP currently owns data about how things are laid out in memory (linker script + particular version of MCU). Sometimes heap is not even contiguous, and can come from different regions. You'd need to take this into account when implementing generic _sbrk().

I recommend keeping it in BSP.

> Seems like this is not necessary to implement for each bps since its pretty standard.  This should probably be moved to the MCU or even to the OS
