jlink: improve USB read during jlink_tap_execute

one to read the data, and one to read the result. However, we can just
do a single larger read instead.

The motivation for this change is a weird problem. If I run the Segger
software before running OpenOCD, then the first read always fails:
Error: usb_bulk_read failed (requested=1, result=0)
Error: jlink_tap_execute, wrong result -107 (expected 1)

Sniffing the USB traffic shows that the J-Link is returning an
overflow error, meaning it is expecting to return the full result
in a single read.

Reason were two cases:

Case one:
The FTD2xx library uses clock_gettime() and in normal cases
the linker will find the function in the libc library. Most

Case two:
You can rebuild the FTD2xx library (relink from the object
files) against the primary (system wide installed) libusb-1.0.
So you avoid mixed code (GPL with proprietary code) in the
FTD2xx library. In this case, the FTD2xx library provides no

configured, including the necessary build host configuration for the

README* refactoring

This is an attempt to bring the README files in line with the current
status of the OpenOCD development.

- remove some obsolete information and duplicated instructions
- reword some statements
- restructure in a way more appealing to a regular user
- add a supported hardware list to allow a potential user to determine
  if his/her usecase is covered by a freetext keyword search through
  the document
- Add OSX notes (courtesy GrizzlyAdams and inca)

Since most ftdi-based adapters are now covered by the ftdi driver, I
think it's ok to remove some of the libftdi/ftd2xx instructions, the
few users who still need them should refer to upstream docs instead.

I'm not sure if README.Windows should come with the DOS line endings,
but i'd expect many windows users to use their silly notepad to view
it, and notepad ignores LF apparently. (Decided to use LF anyway.)

I understand discussing and reviewing such a massive README change is
a somewhat demanding task but I feel it's a necessity to move forward
maintaining proper documentation.

[RFC] target: Move bulk_write_memory to arm7_9

The only remaining user is arm7_9 so remove it from the target API and add
it to struct arm7_9_common to support all its variants with minimal
changes. Many of the variants are likely not correct in the cache/mmu
handling when the bulk write is triggered. This patch does nothing to
change that, except for arm946e, where it was easier to do what might be
the right thing.

mini51: support for Nuvoton NuMicro Mini51 series flash memory

Adds a flash driver for Nuvoton MINI51, MINI52 and MINI54 microcontrollers.

At the moment, it only supports the erase and write operations.

These microcontrollers have a 4 / 8 / 16 KB APROM for application code and a
2 KB LDROM for bootloaders. When the MCU has booted off the APROM, the LDROM
isn't mapped in memory but can be programmed, and the other way around.
This means that the ARM core is typically rebooted for programming. After a
successful write or erase operation, it is rebooted again, using the initial
boot source.

This driver only supports programming the APROM.

This driver is a pure JTAG implementation, it doesn't use any SRAM.

I've tested it on a MINI54ZAN microcontroller using an ST-LINK/V2. With the
microcontroller running at the default clock frequency of 22.1184 MHz, speed
seems to be around 1.1 KB/s.

Error: timeout waiting for algorithm, a target reset is recommended

However, target reset doesn't help as the flag is still there ("Error:

6 years agomdr32fx: support for Milandr's MDR32Fx internal flash memory 32/1532/5
Paul Fertser [Mon, 29 Jul 2013 13:22:07 +0000 (17:22 +0400)]
mdr32fx: support for Milandr's MDR32Fx internal flash memory

This adds example config and flash driver for russian Cortex-M3
microcontroller model.

Run-time tested on MDR32F9Q2I evaluation board; the flash driver
should be compatible with MDR32F2x (Cortex-M0) too but I lack hardware
to test.

There're no status bits at all, the datasheets specifies some delays
for flash operations instead. All being in <100us range, they're hard
to violate with JTAG, I hope. There're also no flash identification
registers so the flash size and type has to be hardcoded into the
config.

The flashing is considerably complicated because the flash is split
into pages, and each page consists of 4 interleaved non-consecutive
"sectors" (on MDR32F9 only, MDR32F2 is single-sectored), so the
fastest way is to latch the page and sector address and then write
only the part that should go into the current page and current sector.

Performance testing results with adapter_khz 1000 and the chip running
on its default HSI 8MHz oscillator:

When working area is specified, a target helper algorithm is used:
wrote 131072 bytes from file testfile.bin in 3.698427s (34.609 KiB/s)

This can theoretically be sped up by ~1.4 times if the helper
algorithm is fed some kind of "loader instructions stream" to allow
sector-by-sector writing.

Pure JTAG implementation (when target memory area is not available)
flashes all the 128k memory in 49.5s.

Flashing "info" memory region is also implemented, but due to the
overlapping memory addresses (resulting in incorrect memory map
calculations for GDB) it can't be used at the same time, so OpenOCD
needs to be started this way: -c "set IMEMORY true" -f
target/mdr32f9q2i.cfg

It also can't be read/verified because it's not memory-mapped anywhere
ever, and OpenOCD NOR framework doesn't really allow to provide a
custom handler that would be used when verifying.

6 years agostlink: add SWO tracing support 24/1524/6
Andrey Yurovsky [Tue, 23 Jul 2013 06:39:51 +0000 (23:39 -0700)]
stlink: add SWO tracing support

Enable reading the SWO trace output via STLinkv2 dongles that support
it.

This adds an optional initialization parameter "trace" with which the user
specifies a destination file where SWO trace output is appended as it comes in
as well as the trace module's source clock rate.

STLink will be configured for a 2MHz SWO data rate (STLink's highest
supported rate) if the source clock is > 2MHz, otherwise the source
clock is used as the data rate directly.

For example:

trace swo.log 168000000

If "trace" is specified with a usable file path, the stlink_usb driver will
attempt to configure and read SWO trace data as follows:
- on _run(), the target's TPI and TMI are configured and the STLinkv2 is told
  to enable tracing.  Only generic ARM TPI and TMI registers are
  configured, any MCU-specific settings (ex: pin routing) are the
  responsibility of the target firmware.  The configuration applied is
  based on the STLinkv2's capabilities (UART emulation).
- on _v2_get_status(), the trace data (if any) is fetched from the
  STLink after the target status is checked and the target is found to
  be running.
- on _halt(), the STLink is told to disable tracing.

When fetching trace data, the entire trace frame is written to the output file
and that data is flushed.  An external tool may be used to parse the
trace data into a more human-readable format.

Tested on ARM Cortex M4F and M3 MCUs (STM32F407 and STM32L152).

gdb_server: support File-I/O Remote Protocol Extension

The File I/O remote protocol extension allows the target to use the
host's file system and console I/O to perform various system calls.

To use the function, targets need to prepare two callback functions:
* get_gdb_finish_info: to get file I/O parameters from target
* gdb_fileio_end: pass file I/O response to target

As target is halted, gdb_server will try to get file-I/O information
from target through target_get_gdb_fileio_info(). If the callback function
returns ERROR_OK, gdb_server will initiate a file-I/O request to gdb.
After gdb finishes system call, gdb will pass response of the system call
to target through target_gdb_fileio_end() and continue to run(continue or step).

To implement the function, I add a new data structure in struct target,
called struct gdb_fileio_info, to record file I/O name and parameters.

Details refer to GDB manual "File-I/O Remote Protocol Extension"
