2011-07-12modified debug test case for shorter loops to enable single steppingTat-Chee Wan (USM)
2011-07-11fix thumb instruction parser for pop pcTat-Chee Wan (USM)
SP was not incremented correctly for the Thumb instruction POP PC opcode.
2011-07-11most set thumb flag for non-matching thumb instruction decode caseTat-Chee Wan (USM)
Thumb bit was not set if there was no matching Thumb instruction found
2011-07-11do not set thumb flag before calling thumb instruction handler routinesTat-Chee Wan (USM)
Pass valid (even) addresses to thumb instruction handler routines. Set Thumb bit (b0) only on return from the handlers.
2011-07-11fix comment textTat-Chee Wan (USM)
2011-07-11fix data abort error due to thumb bit set in instruction addressTat-Chee Wan (USM)
Need to clear thumb flag in _dbg__install_one_breakpoint before accessing memory location, otherwise a Data Abort will be triggered for thumb instructions
2011-07-11updated gdb signal numbers based on ecos headerTat-Chee Wan (USM)
Use actual ECoS header signal definitions
2011-07-11fix invalid values for abort signalsTat-Chee Wan (USM)
Use correct enum defintion macros to define abort signal values
2011-07-11update signal output to handle prefetch and data abortsTat-Chee Wan (USM)
Implement Prefetch and Data Abort Signal enum output
2011-07-11revert b9bb70c16dba4c945b75f1a4b929e2ec304d2874, revise fixTat-Chee Wan (USM)
We need to adjust SP to store SPSR and Aborted Next Instruction Address Revised fix to not update SP for storing Aborted PC to R15 slot, but to copy the adjusted SP value for the R14 slot to R3 instead.
2011-07-11fix incorrect stack pointer offset for debug stack save of abort stateTat-Chee Wan (USM)
SP was not updated after storing Aborted instruction PC to debug stack
2011-07-11remove commented out codeTat-Chee Wan (USM)
2011-07-11handle proper brick socket open and close sequenceTat-Chee Wan (USM)
Allow for multiple GDB sessions from gdb client by opening the brick socket after client connection, and closing the brick socket after client disconnection.
2011-07-11test pc relative loads to pcTat-Chee Wan (USM)
2011-07-11export dbg__display_abort_info symbolTat-Chee Wan (USM)
2011-07-09cleanup abort handler to armdebug interfaceTat-Chee Wan (USM)
2011-07-09preliminary abort exception handlerTat-Chee Wan (USM)
2011-07-09added preliminary abort mode supportTat-Chee Wan (USM)
Interface to platform specific LCD Display routines
2011-07-09added preliminary abort exception supportTat-Chee Wan (USM)
2011-07-09comments and code alignment cleanupsTat-Chee Wan (USM)
2011-07-09thumb mode tests, modified arm mode test for signed comparesTat-Chee Wan (USM)
Thumb mode test routine using Unsigned compares Implement Signed Compares for ARM Mode
2011-07-08code cleanup, fix breakpoint handling logic on entry to debuggerTat-Chee Wan (USM)
When any Breakpoint is triggered, we must restore all active breakpoints. Otherwise, in the case where Normal Breakpoints are active and we encounter a Manual Breakpoint, the Normal Breakpoint will be left dangling (and eventually the breakpoint will be cleared by GDB, destroying the original instruction opcode).
2011-07-08display ctrl-c explicitly in debug informationTat-Chee Wan (USM)
2011-07-06fix syntax errorsTat-Chee Wan (USM)
2011-07-06updated arm condtion code check algorithmTC Wan
The previous ARM Condition Code checking algorithm was incorrect due to an error in the LS condition requirements. Revised algorithm with some code optimization
2011-07-06update comment on nak message processingTat-Chee Wan (USM)
2011-07-06made nak processing more robustTat-Chee Wan (USM)
2011-07-06the previous transmitted message checksum must be cleared before retransmittingTat-Chee Wan (USM)
The previous transmitted message contained a checksum suffix. It must be cleared before retransmission in order to use dbg__putDebugMsg() to retransmit.
2011-07-06send nak '-' immediately upon receiptTat-Chee Wan (USM)
Implement GDB message retransmission from NXT to Host
2011-07-06attempt to fix gdb nak retransmit endless loopTat-Chee Wan (USM)
When GDB sends a NAK (-) but does not receive what it expects, it will keep trying to get a valid response. We just try to retransmit the last message in this case, hopefully GDB will be satisfied.
2011-07-06reorder arm opcode decode table entries to check for more specific instr firstTat-Chee Wan (USM)
ARM BX/BLX instruction share similar opcode prefix with ARM Data instructions. We must check for the BX/BLX instruction first, otherwise the decoder will assume that it is a Data instruction.
2011-07-06fix bug in b and bl offset calculation, code cleanup.Tat-Chee Wan (USM)
B/BL Instruction Parsing routine was not calculating the correct offset. Cleanup debugger stack frame access logic
2011-07-05added gdb step command execution example routineTat-Chee Wan (USM)
2011-07-05refactoring, moved opcode parsing logic to separate fileTat-Chee Wan (USM)
2011-07-05fix step command responseTat-Chee Wan (USM)
Remove ACK response from Step command, let the next breakpoint trigger the Signal response
