* Add comments and tiny improvements to STM32 flash loader algorithmFreddie Chopin2010-11-151-16/+17
| | | | | | | | Add comments to assembly flash loader for STM32. Add tiny improvement in size of the algorithm (40 vs 48 bytes) and tiny speed improvement (~1.5%, as time is wasted on waiting for end of operation anyway). Signed-off-by: Freddie Chopin <freddie_chopin@op.pl>

* stm32: return error when failing to readØyvind Harboe2010-11-091-9/+25
| | | | | | | | | add missing error handling. Output warning when assuming maximum flash size in the family when failing to read. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* flash: remove algorithm exit_point address for supported targetsSpencer Oliver2010-07-201-1/+1
| | | | | | | | | For the above targets the exit_point is optional when used with run_algorithm, so remove it. This makes updating the algorithm less error prone. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>

* stm32 : change returned value of mass_erase functiongcembed2010-06-031-4/+5
| | | | | | | | | | | | | | Hello, "stm32x mass_erase" return ERROR_OK even if something goes wrong. Here is a summary of changes : * in stm32x_mass_erase : return ERROR_FLASH_OPERATION_FAILED when error detected in FLASH_SR register; * in COMMAND_HANDLER(stm32x_handle_mass_erase_command) : return the returned value of stm32x_mass_erase(). I don't know if there is reason to always return ERROR_OK ? Gaëtan
* nor: fix memory leaks during probeSpencer Oliver2010-05-291-0/+6
| | | | | | | Fix similar memory leaks as per commit: ef72484b785ec7462a0415afea679d08b864c7fb Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* NOR: add read() callback to struct flash_driverAntonio Borneo2010-05-161-0/+1
| | | | | | | | | | | | | | Final target is to force bus_width size during CFI flash read. In this first step I need to replace default flash read with flash specific implementation. This patch introduces: - flash_driver_read() layer; - default_flash_read(), backward compatible; - read() callback in struct flash_driver; - proper initialization in every flash_driver instance.

* flash: less bogus errorsØyvind Harboe2010-05-041-1/+1

* STM32 flash erase timeout fixTobias Ringström2010-05-031-2/+2
| | | | | | | | | | | | | | | The current timeout for STM32 flash block erase and flash mass erase is 10 (ms), which is too tight, and fails around 50% of the time for me. The data sheet for STM32F107VC specifies a maximum erase time of 40 ms (for both operations). I'd also consider it a bug that the code does not detect a timeout, but just assumes that the operation has completed. The attached patch does not address this bug. The attached patch increases the timeouts from 10 to 100 ms. Please apply. /Tobias
* stm32x: allow flash probe on a running targetAndreas Fritiofson2010-04-201-6/+0
| | | | | | | | | | | | | | | If the flash has not yet been probed and GDB connects while the target is running, the flash probe triggered by GDB's memory map read will fail. In that case the returned memory map will be empty, causing a subsequent load from within GDB to fail. There's not much you can do from GDB to recover, other than a restart; a 'mon reset init' and manual 'mon flash probe' won't help since GDB has already made up its mind about the memory map. It seems there's no reason to require the target to be halted when probing the flash. Remove the check to let a valid memory map be provided to GDB even when connecting to a running target.

| | | | | | | | | | | | | Make "usage" messages use the same EBNF as the User's Guide; no angle brackets. Improve and correct various helptexts. Don't use "&function"; a function's name is its address. Remove a couple instances of pointless whitespace; shrink a few overlong lines; fix some bad indents.

| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "armv7m.h" the following form should be used. #include <target/armv7m.h> The exception is from .c files in the same directory.
