4 years agocortex_a: fix fast-mode memory reads 22/3122/4
Matthias Welwarsky [Wed, 25 Nov 2015 11:02:32 +0000 (12:02 +0100)]
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

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.

Problem
dap->ap_current is register value, not field value.
it restores invalid ap when it calls dap_ap_select(dap, ap_old) later.

* assume the current ap is 1, dap->ap_current value would be (1 << 24).
ap_old = dap->ap_current;   <-- ap_old = 1<<24 = 0x1000000.
...
dap_ap_select(dap, ap_old); <-- select 0x1000000, not 1.
* All AP registers accessing fail afterwards.

One of the reproducible case(s): CORE residents in AP >= 1
  dap_lookup_cs_component() being used to find PE(*).
  In most cases, PE would be found in AP==0, hence the problem is hidden.
  When AP number is 1, dap->ap_current would have the value of 1<<24.
  Anyone get the AP value with dap->ap_current and resotre it later would
  select the wrong AP and all accessing later would fail.

  The ARM Versatile and/or FPGA would have better chance to provide this

  * PE: Processing Element. AKA Core. See ARM Glossary at

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)
with the following device and target configurations:

 * JTAG: J-Link v8.0, v9.0 and v9.3 with AT91SAM7S256
 * SWD: SiLabs EFM32 STK 3700 (EFM32GG990F1024)
 * SWD: J-Link v8.0, v9.0 and v9.3 with EFM32GG990F1024
 * SWD: XMC 2Go (XMC1100)
 * SWD: XMC1100 Boot Kit (XMC1100)
 * SWD: IAR Systems / Olimex Eval Board (LPC1343F)

 * SWD: SiLabs EZR32 WSTK 6220A (EZR32WG330FG60G)

Except for Windows XP all builds are tested with Clang in addition to
GCC. This patch and libjaylink are not tested on OSX yet.

flash: at91samd: flash write code cleaning

SAMD driver suffered from following problems:

1) Flash was erased as an integral part of flash write.
It was not documented so with usual workflow it resulted
in erasing flash twice (and reducing flash lifespan)
and in almost double flashing time.

2) Sector erase was silently skipped if "is_erased" flag was set.
"is_erased" logic was not reliable, e.g. when a row write
was aborted after successful write of some pages, sector was
still considered as erased. "is_erased" flag could not
cope with flash writes from a user program.

3) Writing of a block with start address unaligned to a flash page
resulted in failed assert and OpenOCD abort.

4) Disabling cache in bit 18 of 16-bit halfword never worked.
MCU implements cache invalidate in hardware so there is no need
to take care about. This bug was reported by Tony DiCola.

New code does not erase flash in write operation.
Instead it traditionally relies on erasing flash beforehand.
"is_erased" logic and cache disabling is completely removed.
It simplifies write procedure a lot and flash write is now faster.

The change partly solves ticket #109 SAMD/SAM4L driver doubles flash erase.

Function is similar to SMAP in ATSAM4L, see http://openocd.zylin.com/2604

Atmel's EDBG adapter handles DSU reset correctly without this change.

A new function dsu_reset_deassert is called as reset-deassert-post event handler.
It optionally prepares reset vector catch and DSU reset is released then.

Additionally SWD clock comment is fixed in at91samdXX.cfg and clock is

flash: New driver for XMC4xxx microcontroller family

This is a complete flash driver for the Infineon XMC4xxx family of
microcontrollers, based on the TMS570 driver by Andrey Yurovsky.
The driver attempts to discover the particular variant of MCU via a
combination of the SCU register (to determine if this is indeed an
XMC4xxx part) and the FLASH0_ID register (to determine the variant).
If this fails, the driver will not load.
The driver has been added to the README and documentation.

Tests:
* Hardware: XMC4500 (XMC4500_relax), XMC4200 (XMC4200 enterprise)
* SWD + JTAG
* Binary: 144k, 1M

Note:
* Flash protect only partly tested. These parts only allow the flash
  protection registers (UCB) to be written 4 times total, and my devkits
  have run out of uses (more on the way)

Future Work:
* User 1/2(permalock) locking support via custom command
* In-memory flash loader bootstrap (flashing is rather slow...)
