Adding support for BeagleBoard.
ArmPkg - Supoprt for ARM specific things that can change as the architecture changes. Plus semihosting JTAG drivers. EmbeddedPkg - Generic support for an embeddded platform. Including a light weight command line shell. BeagleBoardPkg - Platform specifics for BeagleBoard. SD Card works, but USB has issues. Looks like a bug in the open source USB stack (Our internal stack works fine). git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9518 6f19259b-4bc3-4df7-8a09-765794883524

Serial IO Abstraction for GDB stub. This allows an EFI consoles that shows up on the system
|
||||
running GDB. One consle for error information and another console for user input/output.
|
||||
|
||||
Basic packet format is $packet-data#checksum. So every comand has 4 bytes of overhead: $,
|
||||
#, 0, 0. The 0 and 0 are the ascii characters for the checksum.
