2013-04-17program: do not poll target after reset runSpencer Oliver
Disable polling the target before we issue a 'reset run'. This stops errors or warnings if the target disables the SWD or JTAG interface as part of the application code.

This fixes an issue if the device is manually probed after the initial probe fails due to being unable to read flash size register. In this situation the driver assumes the user has overridden the flash size when infact this may not be the case. It also seems on the older stm32f1 devices the flash register is not readable when locked, this does not seem to apply to the newer parts - f0, f3, f4.

2013-02-25stm32: add support for the STM32Lx 384kb dual bank flashJohan Almquist
This update adds support for the STM32Lx 384kb dual bank flash. Previously there was a problem when writing an image that was larger than 192Kb. That lead to openocd printing out two error messages like "Error: access denied / write protected" and "Error: invalid program address". The reason was that the stm32lx driver tried to write half pages which overlapped into the next flash bank. A new configuration file stm32lx_dual_bank.cfg can be used for stm32lx chips with dual bank flash (256kb or 384kb devices). A sanity check was added for probed flash size values to fix the issue seen on some ST samples that answered incorrectly.

An issue has been seen with the stm32lx flash driver that if a power cycle/reset is applied after a erase, any ram loader will Hard Fault on execution. A similar issue is mentioned in the errata for the device. Two solution's seem to workaround this issue: 1, Handle the exception, this means adding exception vectors to the loader and changing the exception address using nvic vtor register. 2. falling back to using slower direct page writes - approx 50% slower. Using solution 1 would mean restrictions are placed on the loader location. Solution 2 was chosen mainly as it was simpler too implement.

2012-10-08stm32f1x: Increase options erase timeoutAndreas Fritiofson
The erase time for the option byte page is not directly specified but is assumed to be the same as the other pages (or mass erase) which is 20 to 40 ms. The current timeout value is 10 which means 10 ms plus the time to poll the status flag that many times. With faster interfaces or drivers (such as when using the ftdi driver instead of the ft2232 driver) the adapter delay is not enough in some cases, unless the jtag freq is reduced as a workaround. The result is a "timed out waiting for flash" error when trying to write the options. Increase the timeout to a minimum of 100 ms, which is in line with the other erase timeouts. Also make defines of both the erase and the program timeouts.

Added a flash driver designed to allow program/erase of memory-mapped SPI flash chips for LPC43xx/LPC18xx family micros. This driver includes three algorithms - erase, write, and SPIFI peripheral initialization (to allow memory-mapped access after a reset). The driver has been added to the flash driver table (drivers.c), and the OpenOCD documentation has been updated to include the flash driver configuration command.

2012-09-26SPI nor drivers refactorGeorge Harris
Moved common SPI flash driver code (device table, common commands) into flash/nor/spi.c and spi.h. Updated flash/nor/stmsmi.c to reflect this refactor.

The stlink interface currently does not support 16bit read/writes. Until a fix is included we issue a error that this is unsupported.

2012-09-07flash: fix sam3 page read/write address computation errorChuen Chou
In at91sam3.c for Atmel SAM3 flash support, there are arithmetic errors in the functions sam3_page_read() and sam3_page_write(). Address locations are computed incorrectly due to an extra addition operation. This leads to memory locations being skipped during flash writes and reads. Smaller programs are written successfully into flash, with memory gaps, while larger programs of legitimate size fail because the skipped memory is not utilized and therefore unavailable. The changes address this condition, and have been tested with an Atmel SAM3X-EK evaluation board.
