2013-03-13jtag: parport: avoid freeing read-only memory sectionStefan Mahr1-2/+2
If command parport_cable is not executed, parport_cable points to const char array in read-only memory as default. On exit free() will try to free this read-only memory. This patch uses strdup to allocate memory when defining default setting.

Because data in is requested too early the USB device will always answer the first USB in by a NAK. That can prevented by a simple reordering of the out and then the in transfer and can improve the Jtag performance for high JTAG clock rates.

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.

2013-01-27jtag: only change state if necessarySpencer Oliver3-3/+12
All the other drivers will only change the state if required. This brings all the other drivers inline with this behaviour. The original issue relates to problems on xscale commit 7989000e0969c1ccf69acbc3ce649a020bc1ee66 Change-Id: Ifc90ec2eef68a70a14f37c00931a07982bfa200c Signed-off-by: Spencer Oliver <spen@spen-soft.co.uk> Reviewed-on: http://openocd.zylin.com/1114 Tested-by: jenkins Reviewed-by: Freddie Chopin <freddie.chopin@gmail.com>

There is no constraint about idProduct in USB spec. So, pids[i] may be 0 for USB devices.

2013-01-27hla: enable DWT component and fix watchpointsSpencer Oliver1-4/+4
The makes sure the DWT component is always enabled so that watchpoints work as expected. This does need merging into the existing cortex_m logic, however at the moment this is non trivial.

2013-01-21flash: add stm32lx loader Hard Fault workaroundSpencer Oliver1-0/+53
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.
