| | | | | | | | | | | | | | | | | | | | | | Clean up treatment of registers in ARMv7-M and Cortex-M3. - At the arch level: * Just list registers and names; don't impose core-specific policy about how they are accessed. * Each register has a symbol. * Remove the register mode field (irrelevant to debugger) - At the core/implementation level: * Just map the registers to their relevant access methods; don't require the arch level to say how that should work (cores other than Cortex-M3 could do it differently). * Don't use undefined bits from register 20. * Use register IDs that are part of the ARMv7-M interface. In short, there's now a real distinction between the arch and core layers. git-svn-id: svn://svn.berlios.de/openocd/trunk@2554 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | Revert parts of the previous ARMv7-M register patch. It turns out that part of the issue is a documentation problem for the Cortex-M3 r1 parts. So for the rest, simpler fixes are possible (in followup patch). git-svn-id: svn://svn.berlios.de/openocd/trunk@2552 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | David Brownell <david-b@pacbell.net>: Some cleanup of the ARMv7-M support: - Reference the relevant ARMv7-M ARM doc (DDI 0405C to non-Vendors), and update the Cortex-M3 doc refs (DDI 0337C is no longer available). - Those registers aren't actually general, and some are incorrect (per all public docs anyway). Update comments and code accordingly. * What the Core Debug facility exposes is *implementation-specific* not architectural. These values aren't fully portable. They match Cortex-M3 ... so no current implementation will make trouble, but the next v7m implementation might. * Four of the registers are actually not exposed that way. Before Cortex-M3 r2p0 they are read/written through MRS/MSR instructions. In that newest silicon, they are four bytes in one register, not four separate registers. - Update the CM3 code to report when that one register is available, and not try to access it when it isn't. Also declare the register numbers that an eventual MRS/MSR solution will need to be using. - Stop line wrapping the exception labels. So for parts before r2p0 OpenOCD behavior is effectively unchanged, and still buggy; but for those newer parts a few things might now be correct. Most current Cortex-M3 parts use r1p1 (or earlier); this seems to include most LM3S parts and all STM32 parts. Parts using r2p0 are available, and include fourth generation LM3S parts ("Tempest") plus AT91SAM3 and LPC17xx parts which are now sampling. git-svn-id: svn://svn.berlios.de/openocd/trunk@2543 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initial support for disassembling Thumb2 code. This works only for Cortex-M3 cores so far. Eventually other cores will also need Thumb2 support ... but they don't yet support any kind of disassembly. - Update the 16-bit Thumb decoder: * Understand CPS, REV*, SETEND, {U,S}XT{B,H} opcodes added by ARMv6. (It already seems to treat CPY as MOV.) * Understand CB, CBNZ, WFI, IT, and other opcodes added by in Thumb2. - A new Thumb2 instruction decode routine is provided. * This has a different signature: pass the target, not the instruction, so it can fetch a second halfword when needed. The instruction size is likewise returned to the caller. * 32-bit instructions are recognized but not yet decoded. - Start using the current "UAL" syntax in some cases. "SWI" is renamed as "SVC"; "LDMIA" as "LDM"; "STMIA" as "STM". - Define a new "cortex_m3 disassemble addr count" command to give access to this disassembly. Sanity checked against "objdump -d" output; a bunch of the new instructions checked out fine. git-svn-id: svn://svn.berlios.de/openocd/trunk@2530 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updates to private TAP state tables in amtjtagaccel interface driver. The first change is the neccesary one to correct a long-standing bug that caused the IDCODE to be shifted by one bit too many. This was caused by an incorrect path from state RESET to state DRSHIFT. The value of those 2 bytes were 0x8a and 0x04. This means that the bitstream to do this transition is 0b 00100 01010 (send LSB first). This will bring you from the reset state to the shift state; however, you enter the shift-state twice, which explains why the ID-CODE that will be read next will be shifted 1 bit. The fix changes these to 0x05 and 0x00. This will send the bitstream 0b 00101 (send LSB first). This will bring the TAP controller from the RESET state to the DRSHIFT state directly, without entering the DRSHIFT state twice. After checking the whole table, two other transitions were found that could be optimized (5 bits in stead of 10 bits). Summary off all changes: From To Old values Old Bitstream New values New Bitstream Remarks ---- ------- ---------- ------------- ---------- ------------- ------- RESET DRSHIFT 0x8a 0x04 0b00100 01010 0x05 0x00 0b00101 1,2 IDLE DRSHIFT 0x85 0x08 0b01000 00101 0x04 0x00 0b00100 2 IDLE IRSHIFT 0x8b 0x08 0b01000 01011 0x06 0x00 0b00110 2 [1] Fixes the IDCODE bug [2] Optimization git-svn-id: svn://svn.berlios.de/openocd/trunk@2472 b42882b7-edfa-0310-969c-e2dbd0fdcd60
