Print "ssize_t" as "%ld" (+ cast to long) not as "%zu".
Official MinGW (gcc 3.4.5) doesn't understand "z" flag.

Otherwise the new alignment checking algorithm thinks that the
address is not aligned, because it is way beyond the last sector.

Resolve a regression when using newish automagic "write_image"
modes, by always padding to the end of affected sectors.
Also document some issues associated with those automagic options,
in the User's Guide and also some related code comments.
We might need similar padding at the *beginning* of some sectors,
but this is a minimalist fix for the problems which have currently
been reported (plus doc updates).

Much to my surprise, I observed a "flash erase_address ..."
command erasing data which I said should not be erased.
The issue turns out to be generic NOR flash code which was
silently, and rather dangerously, morphing partial-sector
references into unrequested whole-sector ones.
This patch removes that low-level morphing. If desired, it
can and should be done in higher level code. (We might need
to fix some stuff in the GDB server code.)

It's currently allocating a big buffer but writing it out in
units of sizeof(host's pointer) ... sub-optimal.

Try to right-size the SRAM buffers, by not:
- using them for very small writes
- giving up when a large buffer isn't available
- allocating buffers much larger than their data
Also don't:
- bother loading the code unless we allocate the writebuffer too
- be so verbose with messaging:
* be more concise
* reduce importance (e.g. DEBUG not WARNING)
* remove duplication
The minimum buffer size is something of a guess. It's eight
times smaller than before, almost the same size as the code
being downloaded. It probably deserves some tuning.
Also, note an erratum affecting flash protection on some chips;
and narrow many over-wide lines affected by the above changes.

Someday revisit various issues: Tempest parts support writing
more than one word at a time; for some target firmware it might
be necessary to save and restore flash IRQ configuration. (The
safest policy is likely to always reset after flash updates.)
Plus swap some undesirable TAB characters with SPACE.

Fix potential memory leak: make sure the per-bank data
structures are only allocated in probe(), and that calling
probe() multiple times is a NOP. Use it for auto_probe().
Require probe() to have done its thing: don't make access
routines cope with it not having been called. Shrink a
bunch of failure paths; and in some cases, correct them.
Don't needlessly insist on a halted target for probe().

Previously "reading" clock info (and part info) also, as a side
effect, wrote the flash timing register. Instead, be more safe:
"reading" should only read. Write paths still refresh timing,
coping with changes the application code may have made.
Also rename the routine which sets flash timing, indicating what
it's really doing; it's got nothing to do with a "mode".

I added the remaining devices and device IDs to stellaris.c, and
removed several devices that don't exist on the Stellaris web page.
Additionally, I found a few devices with duplicate IDs ... the DID1
Version Number for LM3Sxxx parts have DID1 Version = 0x0, and for
LM3Sxxxx have DID1 Version = 0x1. So I extended the comparison to
use the VER and FAM fields from DID1 also.
ID=0x33: LM3S812 (DID1v0) and LM3S2616 (DID1v1)
ID=0x39: LM3S808 (DID1v0) and LM3S2276 (DID1v1)
These are the parts I removed from the file for lack of documentation
(no data sheet to confirm part ID):
LM3S318,
LM3S1101, LM3S1108,
LM3S1615, LM3S1616,
LM3S2016,
LM3S2101, LM3S2108,
LM3S3759, LM3S3768,
LM3S5757, LM3S5767, LM3S5768, LM3S5769,
LM3S6815, LM3S6816,
LM3S6915, LM3S6916,
LM3S6111, LM3S6118.
Also, sort devices according to part number.

Bugfix the read side of flash protection:
- read the right register(s)!
- handle more than 64K
- record the results in the right places
- don't display garbage.
Partially bugfix the write side:
- use 2KB lock regions instead of 1KB pages (!)
- validate input range
- don't try to _remove_ protection (it's write-once)
- #define values we'll need to commit writes.
- ... still doesn't handle pages over 64KB mark, or commit writes
And minor cleanup and fixes:
- get rid of some forward decls
- properly locate a doxygen comment
- fix some bad indentation
- remove superfluous #include
- add a new part ID (many are still missing)
- make the downloaded algorithm code be read-only

Move most declarations in <target/armv4_5.h> to <target/arm.h>
and update users.
What's left in the older file is stuff that I think should be
removed ... the old register cache access stuff, which makes it
awkward to support microcontroller profile (Cortex-M) cores.
The armv4_5_run_algorithm() declaration was moved too, even
though it's not yet as generic as it probably ought to be.

Move the ARM opcode macros from <target/armv4_5.h>, and a few
Thumb2 ones from <target/armv7m.h>, to more appropriate homes
in a new <target/arm_opcodes.h> file.
Removed duplicate opcodes from that v7m/Thumb2 set. Protected
a few macro argument references by adding missing parentheses.
Tightening up some of the line lengths turned up a curious artifact:
the macros for the Thumb opcodes are all 32 bits wide, not 16 bits.
There's currently no explanation for why it's done that way...

Move the bulk of the flash.h file into flash/nor/core.h, leaving an
empty husk that will be removed in the next patch.
The NOR driver structure is an implementation detail, so move it into
its own private header file <flash/nor/driver.h> along with helper
declaration for finding them by name.
|
|
|
|
|
| |
The flash.h header does not require the target.h header file, but
its implementation source files do. Move it to flash/nor/imp.h.

Splits the exec mode commands out of flash.c into the flash/nor/ files.
The routines used by these high-level commands are moved into nor/core.c,

The newly moved flash TCL routines access the internals of the module
too much. Fix the layering issues by adding new core NOR flash APIs:
<flash/nor/core.h>:
- flash_driver_find_by_name() - self-descriptive
<flash/nor/imp.h>:
- flash_bank_add() - encapsulates adding banks to bank list
- flash_bank_list() - encapsulates retreiving bank list
This allows the externs in flash/nor/imp.h to be removed, and
these mechanisms may now be re-used by other flash module code.
|
|
|
|
|
|
| |
Moves the top-level 'flash' command handlers into flash/nor/tcl.c,
with flash/nor/imp.h providing an internal implementation header
to share non-public API components.

With all #include directives converted, we only need to have the

Before we can -I the top-level src/ directory alone, references to
"hello.h" must be updated. This is an internal header, so it does
not need angle brackets.
