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

223 * channel_BOOT messages
227 /* The BOOT agent only supports a few messages. They are used purely
228 * to control the "start-of-day" connection to a host program. All
229 * Angel systems with host communications *MUST* provide the BOOT
230 * agent, even if they don't have support for either the single- or
231 * multi-threaded debug agents.
233 * The way the BOOT channel will be used on startup will be as follows:
235 * a) Target board is powered up before host debugger is invoked
237 * After switching on the target and initialisation is completed the
238 * target will send an ADP_Booted or ADP_Reset message. The debugger
239 * has not been started yet so this message will not be received. In
240 * a serial world this makes it important that any buffers on the host
241 * side are flushed during initialisation of the debugger, and in an
242 * Ethernet world it makes it important that the target can cope with the
243 * message not being received.
245 * Eventually the Debugger will be started up and will send an
246 * ADP_Reboot or ADP_Reset request. The target will respond to this with
247 * an ADP_Reboot or ADP_Reset acknowldege and will then reboot, finally
248 * sending an ADP_Rebooted when it has done all it needs to do (very little
249 * in the case of ADP_Reset, but completely rebooting in the case of
250 * ADP_Reboot). Note that it is important that an ADP_Rebooted message is
251 * sent so that the Debugger does not attempt to send any data after it has
252 * made a request to ADP_Reboot and before it receives an ADP_Rebooted, as
253 * data can be lost be the target during this time.
255 * The target and host are now ready to start a debug session.
257 * b) Target board is powered up after host debugger is invoked
259 * The debugger will send an ADP_Reboot or ADP_Reset request, but will
260 * receive no reply until the target is powered up.
262 * When the target is powered up then it will send an ADP_Rebooted
263 * message to the debugger. The debugger should accept this message
264 * even though it has received no ADP_Reboot or ADP_Reset acknowldege message
267 * The target and host are now ready to start a debug session.
270 * If at any point during the bootup sequence and ADP messages are
271 * sent down the S_DBG channel then they should be responded to with a
272 * RDI_NotInitialised error. [This should never happen however].
274 * An ADP_Boot or ADP Rebooted message should be accepted at
275 * any point, since it is possible for a catastrophe to occur (such as
276 * disconnecteing the host and target during a debug message) which
277 * requires that one or other end be reset.
