2020-12-02adi_v5_swd: wait for readable DPIDR, ABORT if stalledTomas Vanek1-13/+56
Reading of DPIDR is the very first operation after JTAG to SWD sequence. Without this change if DPIDR read fails then swd connect fails. Keep trying JTAG to SWD sequence and DPIDR read until success or timeout 0.5 sec. It makes setting of adapter srst delay on SWD transport mostly unnecessary. Also test for ERROR_WAIT (which should not occur according to IHI 0031E B4.3.2 but a quirk is known) and if bus is kept stalled then issue abort to make the next connect possible.

2020-01-14adapter: switch from struct jtag_interface to adapter_driverAntonio Borneo1-3/+3
To reorganize the adapters code, introduce an adapter_driver struct that contains all the adapter generic part, while keeping in two separate struct the specific API jtag_ops and swd_ops. Move the allocation of *adapter_driver from the JTAG-specific file core.c to the more adapter-specific file adapter.c While splitting the old jtag_interface for every driver, put the fields in the same order as in the struct declaration so we keep a consistent code across all the drivers. While other transport specific API could/would be added as separate ops, nothing is done here for HLA.

2020-01-14swd: get rid of jtag queue to assert/deassert srstAntonio Borneo1-1/+1
The transport SWD uses the JTAG queue to assert/deassert the system reset srst. This is the major inconsistency that has to be removed to properly split JTAG and SWD. Introduce a new driver API, reset(), to controls both the signals trst and srst in the driver, skipping the JTAG queue. Put the new API in struct jtag_interface, even if in this patch it's used for SWD only; the goal is to get it reused by the other transports. Add the implementation of the API in all the drivers that implement SWD. Such implementation is almost the same of the old code in JTAG queue. Create a wrapper adapter_system_reset() to use the new API and remove the SWD specific swd_add_reset(). In the wrapper replace jtag_add_sleep() with jtag_sleep(), because the former uses the JTAG queue too. Rename the old jtag_add_reset() as legacy_jtag_add_reset() with the target to remove it when all drivers would be ported to the new reset API. Create a new jtag_add_reset() that calls the legacy function for drivers still on the old reset API. Use the new API also on JTAG transport for the drivers that can support both SWD and JTAG. For the moment, do not modify the implementation of JTAG-only drivers, which will continue using the usual method. This should be cleaned-up in future commits.

2019-01-30arm_adi_v5: rewrite dap_to_jtag and dap_to_swdAntonio Borneo1-65/+0
The functions dap_to_jtag() and dap_to_swd() have been introduced by 3ef9beb52cd0 ("ADIv5 DAP ops switching to JTAG or SWD modes") in arm_adi_v5.c by using the JTAG queue only. Later, in 6f8b8593d63b ("ADIv5 transport support moves to separate files") the functions has been moved in adi_v5_swd.c and adi_v5_jtag.c but keeping the dependency from JTAG queue. The functions does not work if the current transport is not JTAG. Move back the functions in arm_adi_v5.c, replace the input parameter "target" with "dap", use the transport to detect if the JTAG queue is present, in case of SWD transport use the proper method, for other transports report error. Reuse the ADI v5 sequences already present in jtag/swd.h. Also, OpenOCD does not support switching to another transport after the initial selection, so do not change DAP's ops vector.

2018-07-24arm_adi_v5: put SWJ-DP back to JTAG mode at exitAntonio Borneo1-0/+11
When SWD mode is used, current OpenOCD code left the SWJ-DP in SWD mode at exit. Also, current code is unable to switch back the SWJ-DP in JTAG at next run, thus a power cycle of both target and interface is required in order to run OpenOCD in JTAG mode again. Put the SWJ-DP back to JTAG mode before exit from OpenOCD. Use switch_seq(SWD_TO_JTAG) instead of dap_to_jtag(), because the latter is not implemented on some interfaces. This is aligned with the use of switch_seq(JTAG_TO_SWD) in swd_connect().

2018-01-05arm_adi_v5: fix wrong addressing after change of CSW_ADDRINCTomas Vanek1-1/+1
Problem: If the same memory location is accessed alternatively by MEM-AP banked data registers without autoincrement and by standard autoincremented read/write, TAR register is not updated correctly. How to replicate: On a Cortex-M issue mdw 0xe000edf0 multiple times. When poll is on (poll reads the same memory location) only the first read is correct. 0xe000edf0: 01000000 0xe000edf0: 00000000 0xe000edf0: 20002640 0xe000edf0: 01000000 0xe000edf0: 00000000 0xe000edf0: 00000000 No problems with poll off. 0xe000edf0: 01000000 0xe000edf0: 01000000 0xe000edf0: 01000000 mem_ap_setup_tar() writes to MEM_AP_REG_TAR if requested TAR value changed or CSW_ADDRINC_... is currently active. However if an autoincremented access has been issued and autoinc switched off in CSW afterwards, TAR does not get updated. The change introduces mem_ap_update_tar_cache() which is called after queuing of any access to MEM_AP_REG_DRW. It simulates TAR increment to keep tar_value in sync with MEM_AP. Crossing tar autoincrement block boundary invalidates cached value. mem_ap_write() and mem_ap_read() do not check tar autoincrement block boundary, mem_ap_setup_tar() is called before each transfer instead. dap_invalidate_cache() is introduced to ensure invalidation of all cached values during dap_dp_init() and swd_connect() Change-Id: I815c2283d2989cffd6ea9a4100ce2f29dc3fb7b4 Signed-off-by: Tomas Vanek <vanekt@fbl.cz> Reviewed-on: http://openocd.zylin.com/4162 Tested-by: jenkins Reviewed-by: Christopher Head <chead@zaber.com> Reviewed-by: Andreas Fritiofson <andreas.fritiofson@gmail.com>

2014-01-09cmsis-dap: add initial cmsis-dap supportSpencer Oliver1-5/+29
This is based on work from: https://github.com/TheShed/OpenOCD-CMSIS-DAP/tree/cmsis-dap Main changes include moving over to using HIDAPI rather than libusb-1.0 and cleaning up to merge into master. Support for reset using srst has also been added. It has been tested on all the mbed boards as well as the Freedom board from Freescale. These boards only implement SWD mode, however JTAG mode has been tested with a Keil ULINK2 and a stm32 target - but requires a lot more work.

2013-10-31Clean up many C99 integer types format specifiersPaul Fertser1-2/+2
This eliminates most of the warnings reported when building for arm-none-eabi (newlib). Hsiangkai, there're many similar warnings left in your nds32 files, I didn't have the nerve to clean them all, probably you could pick it up.

2011-06-13transport: move files over to transport folderØyvind Harboe1-1/+1
as we introduce swd and jtag as two transports, we want to start up with a new transport folder to organize the code a bit.
2010-12-24initial SWD transport (SWD infrastructure #2)David Brownell1-6/+275
This piggy backs on JTAG so it's not yet pretty, but that seems unavoidable so far given today's OpenOCD internals. SWD init and data transfer are unfinished and untested, but that should cause no regressions, and will be addressed by the time drivers start using this infrastructure. Checking in whould get the code working better sooner, and turn up any structural/architectural issues while they're easier to fix. The debug adapter drivers will provide simple SWD driver structs with methods that kick in as needed (instead of JTAG). So far just one adapter driver has been updated (not yet ready to use or circulate). The biggest issues are probably - fault handling, where the ARM Debug Interface V5 pipelining needs work in both JTAG and SWD modes and - missing rewrite of block I/O code to work on both of our Cortex-ready transports (Current code is hard-wired to JTAG); relates also to the pipelining issue. - omitted support to activate/deactivate SWO/SWV trace (this is technically trivial, but configuring what to trace is NOT.

2010-03-16ADIv5 transport support moves to separate filesDavid Brownell1-0/+92
Unclutter arm_adi_v5.c by moving most transport-specific code to a transport-specific files adi_v5_{jtag,swd}.c ... it's not a full cleanup, because of some issues which need to be addressed as part of SWD support (along with implementing the DAP operations on top of SWD transport): - The mess where mem_ap_read_buf_u32() is currently coded to know about JTAG scan chains, and thus needs rewriting before it will work with SWD; - Initialization is still JTAG-specific Also move JTAG_{DP,ACK}_* constants from adi_v5.h to the JTAG file; no other code should care about those values.
