dragonmux 29dc94c3d6 hosted: with mubes help, fixes some issues with how we talk CMSIS-DAP 2022-05-17 15:46:33 -07:00
dragonmux 54f577a970 hosted/dap: Partial revert of 5c8e277, taking into account that division may not be available on platforms 'hosted' might see itself built 2022-03-14 21:37:44 -07:00
Uwe Bonnes a4caec29b9 dap_swdptap_seq_out: Write only needed data
Dragonprobe (origin/cmsisdap-fixes, 211031) hanged on additional byes in the
SWJ_Sequence request.

Uwe Bonnes 07b4e5726e CMSIS-DAP: Run time detect DAP_SWD_SEQUENCE
Some dongles in the making like orbtrace may not yet support.

Uwe Bonnes 88e44d1c12 cmsis: use exception in wait_word(). 2021-10-31 12:55:41 +01:00
Uwe Bonnes a1d4649795 SWD: Use dp_low_write to allow multidrop scan. 2021-10-31 12:55:41 +01:00
Uwe Bonnes f9d343af3e cmsis: AP reads are posted. Read from RDBUFF. 2021-10-31 12:55:41 +01:00

Uwe Bonnes 166eb3ee3e cmsis_dap: Always transfer 65 bytes with hid_read|write()
CMSIS-DAP Dragonprobe works on some devices. E.g. it does not work
on NUCLEO-F103

Uwe Bonnes 761e0230d4 cmsis-dap: Print messages when transfers fail.
Expect signal integrity errors when using jumper cables. Often probes switch
the SWJ GPIO with highest speed, resulting in possible reflections. Additional
ground wires may help. If there is isolation between probe and targets,
additional ground wires are a must or ground shift will wrack the transfer!

Uwe Bonnes 485105221e dap: Always work on a copy of the buffer when calling dbg_dap_cmd() in a loop
A better solution would use seperate buffers for dbg_dap_cmd. But as WAIT is
already handled in DAP, cahnces are low that loop re-entry is needed.

Vegard Storheil Eriksen 7ccbdd98c0 hosted/dap: Copy command buffer in wait/retry loop.
The same buffer is used for both command and response, causing part of
the command to be overwritten before it’s retried. Solve this by saving
and restoring a copy of the command before retrying.

Uwe Bonnes 877a6e694c Revert "cmsis_dap: Always write full reportsize + 1 buffers"
This reverts commit 61e237ec87.
This makes a CMSIS-DAP probe with version < 1.2 work again on DP V1 devices.
Status of other combination unknown:
    DP  V1 V2 V2/Multidrop
Probe
<  1.2  ok ok --
>= 1.2   ? ?  ?

Uwe Bonnes ea92c8b8c8 cmsis-dap: Allow to use adiv5_swdp_scan. 2021-04-21 21:50:38 +02:00
Uwe Bonnes 61e237ec87 cmsis_dap: Always write full reportsize + 1 buffers
Expect short reads and other errors else

Uwe Bonnes d6ade4d94e cmsis-dap: Use SWD_SEQUENCE if available. 2021-04-21 21:50:04 +02:00
Uwe Bonnes 13e8a262e4 SWJ Frequency: Implement for cmsis-dap 2020-12-12 18:33:09 +01:00
Uwe Bonnes 0995fe1288 cmsis-dap: Various fixes
- decrease report size to 64, otherwise MIMRXT10x0-EVK crashed when
  reading larger memory block
- dp_read_reg acts direct, fixing CortexM core register read.
- length of data to write with read_block.

Uwe Bonnes cdd07544d5 Cortexm: Allow pure debug on devices not yet handled for flashing
- Recognize STM32L552 and MIMXRT10XX
- Fix another PIDR
- Fix bad debug print string.

Uwe Bonnes 3d92b82678 jtag: Use index and not device structure for jtag_dev_write_ir and jtag_dev_shift_dr 2020-10-16 20:03:03 +02:00
Uwe Bonnes 7ccf0d3e03 jtag_dev_t: Make dev, idcode and desc less generic.
No codechange intended.

Uwe Bonnes 998a9747f8 cmsis_dap: Make some errors more prominent. 2020-08-16 15:20:58 +02:00
Uwe Bonnes dc3fd2eb06 Classify debug messages
Firmware BMP with ENABLE_DEBUG=1 will print WARN and INFO as before.
PC-Hosted BMPwill alway print to stderr. Warn is printed unconditional,
INFO, GDB, TARGET, DONGLE and WIRE will print if their appropriate bit in
cl_debuglevel is set via the -v verbose command line argument.
INFO will go to stdout with -t or -l.
