|
* INTRODUCTION
|
|
* ------------
|
|
* The early RDP message definitions were held in an ARM Ltd "armdbg"
|
|
* source file. Since the relevant header files were not exported
|
|
* publicly as part of an ARM Ltd core tools release, it was a problem
|
|
* for developers manipulating the target side of the protocol.
|
|
*
|
|
* For Angel, this new (ANSI 'C' clean) header file defines the ADP
|
|
* protocol. The header should be useable by both host and target
|
|
* systems, thus avoiding problems that can arise from duplicate
|
|
* definitions. Care has been taken in the construction of this header
|
|
* file to avoid any host/target differences.
|
|
*
|
|
* MESSAGE FORMAT
|
|
* --------------
|
|
* Format of the "data" section of debug and boot agent messages. This is
|
|
* the standard ADP (Angel Debug Protocol) message format:
|
|
*
|
|
* unsigned32 reason - Main debug reason code.
|
|
* unsigned32 debugID - Information describing host debug world;
|
|
* - private to host and used in any target initiated
|
|
* messages.
|
|
* unsigned32 OSinfo1 \ Target OS information to identify process/thread
|
|
* unsigned32 OSinfo2 / memory/world, etc. These two fields are target
|
|
* defined.
|
|
* byte args[n] - Data for message "reason" code.
|
|
*
|
|
* NOTE: The message format is the same for single threaded debugging,
|
|
* except that the "OSinfo" fields should be -1 (0xFFFFFFFF). Even
|
|
* single-threaded debugging *MAY* have different host specified
|
|
* debugID values, so the Angel debug system will preserve the "debugID"
|
|
* information for replies, and the relevant asynchronous target-to-host
|
|
* messages. The "debugID" is defined by the host-end of the
|
|
* protocol, and is used by the host to ensure that messages are
|
|
* routed to the correct handler program/veneer.
|
|
*
|
|
* The reason there are two target specified "OSinfo" words is because
|
|
* thread identifiers may not be unique when processes/tasks have
|
|
* private virtual address spaces. It allows more flexibility when
|
|
* supporting multi-threaded or O/S aware debugging.
|
|
*
|
|
* NOTE: The reason that there is no "size" information, is that the
|
|
* message IDs themselves encode the format of any arguments. Also it
|
|
* would be a duplication of information used by the physical
|
|
* transport layer (which is distinct from this logical message
|
|
* layer). Any routing of messages through programs, hosts,
|
|
* etc. should be performed at the physical layer, or the boundaries
|
|
* between physical layers. i.e. packet received on socket in host,
|
|
* and transferred to serial packet for passing on down the line.
|
|
*
|
|
* NOTE: Pointers aren't passed in messages because they are dangerous in
|
|
* a multi-threaded environment.
|
|
*
|
|
* ADP REASON CODE
|
|
* ---------------
|
|
* The message reason codes contain some information that ties them to
|
|
* the channel and direction that the message will be used with. This
|
|
* will ensure that even if the message "#define name" is not
|
|
* completely descriptive, the message reason code is.
|
|
*
|
|
* b31 = direction. 0=Host-to-Target; 1=Target-to-Host;
|
|
* b30-28 = debug agent multi-threaded control (see below)
|
|
* b27-24 = reserved. should be zero.
|
|
* b23-16 = channelid. The fixed Angel channel number
|
|
* (see "channels.h").
|
|
* b15-0 = message reason code.
|
|
*
|
|
* It is unfortunate that to aid the error-checking capabilities of
|
|
* the Angel communications we have changed the message numbers from
|
|
* the original ARM Ltd RDP. However this also has benefits, in that
|
|
* the Angel work is meant to be a clean break.
|
|
*
|
|
* However, it isn't so bad since even though the numbers are
|
|
* different, the majority of the reason codes have exactly the same
|
|
* functionality as the original RDP messages.
|
|
*
|
|
* NOTES
|
|
* -----
|
|
* It would be ideal to use "rpcgen" (or some equivalent) to
|
|
* automatically maintain compatibility between the target and host
|
|
* ends of the protocol. However, ARM Ltd expressed that the message
|
|
* handling should be hand-coded, to avoid dependance on external
|
|
* tools.
|
|
*
|
|
* All other channels have undefined data formats and are purely
|
|
* application defined. The C library "_sys_" support will provide a
|
|
* veneer to perform message block operations as required.
|
|
*
|
|
* It is IMPLIED that all of the ADP messages will fit within the
|
|
* buffer DATASIZE. This has a minimum value, calculated from
|
|
* BUFFERMINSIZE.
|
|
*
|
|
* All messages are passed and received to the channel system in little
|
|
* endian order (ie. use little endian order when writing a word as
|
|
* a sequence of bytes within a message).
|
|
*
|
|
* A reply / acknowledgement to an ADP message is always sent and has the
|
|
* same reason code as the original except that the TtoH / HtoT bit is
|
|
* reversed. This makes it simple to check that the reply really
|
|
* is a reply to the message which was just sent! [Boot Channel messages
|
|
* also require that this protocol is used].

|
|
* agent, even if they don't have support for either the single- or
|
|
* multi-threaded debug agents.
|
|
*
|
|
* The way the BOOT channel will be used on startup will be as follows:
|
|
*
|
|
* a) Target board is powered up before host debugger is invoked
|
|
*
|
|
* After switching on the target and initialisation is completed the
|
|
* target will send an ADP_Booted or ADP_Reset message. The debugger
|
|
* has not been started yet so this message will not be received. In
|
|
* a serial world this makes it important that any buffers on the host
|
|
* side are flushed during initialisation of the debugger, and in an
|
|
* Ethernet world it makes it important that the target can cope with the
|
|
* message not being received.
|
|
*
|
|
* Eventually the Debugger will be started up and will send an
|
|
* ADP_Reboot or ADP_Reset request. The target will respond to this with
|
|
* an ADP_Reboot or ADP_Reset acknowldege and will then reboot, finally
|
|
* sending an ADP_Rebooted when it has done all it needs to do (very little
|
|
* in the case of ADP_Reset, but completely rebooting in the case of
|
|
* ADP_Reboot). Note that it is important that an ADP_Rebooted message is
|
|
* sent so that the Debugger does not attempt to send any data after it has
|
|
* made a request to ADP_Reboot and before it receives an ADP_Rebooted, as
|
|
* data can be lost be the target during this time.
|
|
*
|
|
* The target and host are now ready to start a debug session.
|
|
*
|
|
* b) Target board is powered up after host debugger is invoked
|
|
*
|
|
* The debugger will send an ADP_Reboot or ADP_Reset request, but will
|
|
* receive no reply until the target is powered up.
|
|
/ *
|
|
* When the target is powered up then it will send an ADP_Rebooted
|
|
* message to the debugger. The debugger should accept this message
|
|
* even though it has received no ADP_Reboot or ADP_Reset acknowldege message
|
|
* from the target.
|
|
*
|
|
* The target and host are now ready to start a debug session.
|
|
*
|
|
*
|
|
* If at any point during the bootup sequence and ADP messages are
|
|
* sent down the S_DBG channel then they should be responded to with a
|
|
* RDI_NotInitialised error. [This should never happen however].
|
|
*
|
|
* An ADP_Boot or ADP Rebooted message should be accepted at
|
|
* any point, since it is possible for a catastrophe to occur (such as
|
|
* disconnecteing the host and target during a debug message) which
|
|
* requires that one or other end be reset.
