adi_v5_swd: Avoid special handling the SELECT cache during connect

The cache is forced to zero to match the value expected by the DPIDR read
so the connect sequence is not destroyed by a SELECT update.

However, DPIDR and in fact all registers except address 4 are independent
of the current DPBANKSEL value. Change swd_queue_dp_bankselect() to use
this fact and avoid touching SELECT for those registers.

At certain times (when dap_run() is called), the journal is inspected
for WAIT responses and all discarded accesses are replayed to complete
them. Special care is taken to not re-execute already successfully

Peter Lawrence [Mon, 28 Dec 2015 21:53:49 +0000 (22:53 +0100)]
ARM ADIv5: CoreSight ROM decode part number and designer id

The existing arm_adi_v5.c code decodes CoreSight peripherals based
on the part number field.  However, these are specific to a
particular manufacturer (often ARM).  The same part number from
two different manufacturers (distinct designer ids) should not
decode as the same CoreSight peripheral.

The Analog Devices ADSP-SC58x and ADSP-BF70x have peripherals that
overlap with existing OpenOCD decoding.  The part number is the
same as existing OpenOCD decoding, but have a different JEP106 code.

Most, if not all, of the existing part number entries in
arm_adi_v5.c are probably specific to ARM. Change all entries
suspected to be designed by ARM to match only ARM's designer ID.

However, to preserve legacy behavior, existing non-ARM entries are
encoded with a wildcard so that they will behave in the same way as
the existing legacy code.  It is desirable, however, to start
encoding the data with designer codes to avoid such ambiguity.

Revising the code to check both the part number and designer id
seemed to a warrant a const array lookup table instead of a
multi-tiered switch statement.

Also try to sync part identification IDs with relevant ARM docs.

cortex_a: fix fast-mode memory reads

cortex_a_read_apb_ab_memory_fast() uses the wrong order of ITR and DSCR
writes when setting up the transfer. ARM DDI0406C says in C8.2 regarding
"Fast mode" operation to first switch to fast mode and then latch the
instruction in ITR. Current implementation first wrote ITR, causing
the instruction to be executed immediately, then switched to fast mode
without an instruction latched. Repeated reading of DTRTX didn't
execute LDC and thus replicated its current content into the whole buffer.

This patch uses the following, revised algorithm:
1) switch to non-blocking mode and issue the LDC for the first word
2) if more than one word is to be read:
 - switch to fast mode
 - latch the LDC instruction into ITR (it is _not_ executed)
 - issue (count-1) reads of DTRTX register, each read returns the current
   content of DTRTX and re-issues the latched instruction
 -> now the second-to-last word is in the buffer and the LDC for the last
    word has been issued.
3) wait for the last instruction to complete
4) switch back to non-blocking mode
5) Read DTRTX for the last (or: only) word and put it into the buffer

4 years agocortex_a: replace cortex_a_check_address function 19/3119/7
Matthias Welwarsky [Tue, 24 Nov 2015 14:59:59 +0000 (15:59 +0100)]
cortex_a: replace cortex_a_check_address function

When accessing memory through the ARM core, privilege levels and mmu
access permissions observed. Thus it depends on the current mode of the
ARM core whether an access is possible or not. the ARM in USR mode can
not access memory mapped to a higher privilege level. This means, if the
ARM core is halted while executing at PL0, the debugger would be
prevented from setting a breakpoint at an address with a higher privilege
level, e.g. in the OS kernel. This is not desirable.

cortex_a_check_address() tried to work around this by predicting if an
access would fail and switched the ARM core to SVC mode. However, the
prediction was based on hardcoded address ranges and only worked for
Linux and a 3G/1G user/kernel space split.

This patch changes the policy to always switch to SVC mode for memory
accesses. It introduces two functions cortex_a_prep_memaccess() and
cortex_a_post_memaccess() which bracket memory reads and writes. These
function encapsulate all actions necessary for preparation and cleanup.

4 years agoImprove J-Link driver and introduce libjaylink. 98/2598/8
Marc Schink [Mon, 20 Oct 2014 17:18:38 +0000 (13:18 -0400)]
Improve J-Link driver and introduce libjaylink.

This patch uses libjaylink which is a library to access J-Link
devices. As other tools which are not in the scope of OpenOCD also
need to access J-Link devices a library is used. A firmware upgrade
tool and an advanced configuration tool for J-Link devices are under
development.

Further versions of libjaylink will support additional features
OpenOCD could benefit from. This includes TCP/IP as additional
possibility to connect to J-Link devices as well as power tracing and
device internal communication. The latter is used to access
peripherals on some development boards (e.g EFM32 STK and DVK).

Integration of libjaylink is realized with a git submodule like
jimtcl. As libjaylink depends on libusb-1.0 only, no additional
dependency is introduced for OpenOCD.

All low-level JTAG and SWD implementations of the current driver are
left untouched and therefore no incompabilities are to be expected.

Improvements of this patch:

 * Support for more USB Product IDs, including those with the new
   scheme (0x10xx). The corresponding udev rules are also updated.
 * Device selection with serial number and USB address.
 * Adaptive clocking is now correctly implemented and only usable for
   devices with the corresponding capability.
 * The target power supply can now be switched without the need for
   changing configuration and power cycling the device.
 * Device configuration is more restrictive and only allowed if the
   required capabilities are available.
 * Device configuration now shows the changes between the current
   configuration of the device and the values that will be applied.
 * Device configuration is verified after it is written to the device
   exactly as the vendor software does.
 * Connection registration is now handled properly and checks if the
   maximum number of connections on a device is reached. This is also
   necessary for devices which are attached via USB to OpenOCD as
   some device models also support connections on TCP/IP.
 * Serial Wire Output (SWO) can now be captured. This feature is not
   documented by SEGGER however it is completely supported by
   libjaylink.

This patch and libjaylink were tested on Ubuntu 14.04 (i386),
Debian 7 (amd64), FreeBSD 10.0 (amd64) and Windows XP SP3 (32-bit)
