* NOR/CFI: minor code cleanupAntonio Borneo2010-05-161-8/+0
| | | | | | | Remove few LOG_DEBUG() messages, together with code and variables required to build such messages. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR/CFI: add cfi_read() implementationAntonio Borneo2010-05-161-2/+72
| | | | | | | | | | Final step to force bus_width size during CFI flash read. Added CFI specific implementation cfi_read() that uses only accesses at bus_width size. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR: add read() callback to struct flash_driverAntonio Borneo2010-05-1623-1/+72
| | | | | | | | | | | | | | 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.

* NOR/CFI: remove use of cfi_add_byte()Antonio Borneo2010-05-161-40/+1
| | | | | | | Remove the function cfi_add_byte() and rewrite the only instance of it. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR/CFI: use bus_width for memory access in cfi_write()Antonio Borneo2010-05-161-54/+15
| | | | | | | | | | | | | | During cfi_write(), head and tail of destination area could be not aligned to bus_width. Since write operation must be at bus_width size, source buffer size is extended and buffer padded with current values read from flash. Force using bus_width to read current value from flash. Do not use cfi_add_byte() anymore, to allow removing this function later on. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR/CFI: use bus_width for memory access on flash ID.Antonio Borneo2010-05-161-25/+22
| | | | | | | | | | NOR flash structure requires each access to be bus_width wide. Fix read of flash ID accordingly to rule above. Add case (chip_width == 4), allowed by CFI spec and coherent with current value of CFI_MAX_CHIP_WIDTH but currently not used by any target. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR/CFI: identify memory accesses not using "bus_width".Antonio Borneo2010-05-161-0/+8
| | | | | | | | | | | | | | | | | | | | Since NOR flash devices does not handle "byte enable lanes", each read/write access involves the whole "chip_width". When multiple devices are in parallel, usually all chips are enabled during each access. All such cases are compatible with flash accesses at "bus_width" size. Access at "bus_width" size is mandatory for write access to avoid transferring of garbage values to flash. During read access the flash controller should take care, and discard unneeded bytes. Anyway, it is good practice to use "bus_width" size also for read. Every memory access that does not respect "bus_width" size is marked with a "FIXME" comment.

* NOR/CFI: simplify bufferwsize computationAntonio Borneo2010-05-161-39/+10
| | | | | | | | | | | | | | | | | | | | | | | | | Review and simplify computation of bufferwsize. Add comments about variables' meaning. The same code is present 3 times in the file. Current patch updates all the 3 instances. Step 1) Replace "switch(bank->chip_width) {...}". Illegal values of bank->chip_width are already dropped. For legal values, the code is equivalent to: bufferwsize = buffersize / bank->chip_width; Step 2) The above code replacement plus the following line: bufferwsize /= (bank->bus_width / bank->chip_width); is merged in a single formula: bufferwsize = (buffersize / bank->chip_width) / (bank->bus_width / bank->chip_width); and simplified as: bufferwsize = buffersize / bank->bus_width; Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR/CFI: check "flash bank" command argumentsAntonio Borneo2010-05-161-1/+11
| | | | | | | | | | | | | | | | | | Arguments chip_width and bus_width of command "flash bank" are not fully checked. While bus_width is later on redundantly checked in several other parts (e.g. in cfi_command_val()) and generates run-time error, chip_width is never checked, nor related to actual bus_width value. Added check to avoid: - (chip_width == 0), that would mean no memory chip at all, avoiding also division by zero e.g. in cfi_get_u8(); - (bus_width == 0), that would mean no bus at all; - unsupported cases of chip_width or bus_width value not power of 2; - unsupported case of chip width wider than bus.

* Fujitsu MBM29SL800TE flash supportKarl Kurbjun2010-05-112-0/+18
| | | | | | | | | | | | | | | | | Hi, This is my first post to the list. First, I would like to thank everyone for their work on OpenOCD, it is a great tool to work with. I have been using it to debug code on hardware for the Rockbox project (www.rockbox.org). The target that I primarily work with has a Spansion/Fujitsu NOR flash (MBM29SL800TE). I attached a patch that adds support for this flash. I hope it can be included in the main repository. If there is something that needs to be changed with the patch before inclusion please let me know. -Karl Kurbjun

* flash: stop caching protection stateØyvind Harboe2010-05-054-126/+31
| | | | | | | | | | | | | | There are a million reasons why cached protection state might be stale: power cycling of target, reset, code executing on the target, etc. The "flash protect_check" command is now gone. This is *always* executed when running a "flash info". As a bonus for more a more robust approach, lots of code could be deleted. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* gdb: connect will now fail if flash autoprobe failsØyvind Harboe2010-05-053-21/+21
| | | | | | | | | | | | This stops GDB from launching with an empty memory map, making gdb load w/flashing fail for no obvious reason. The error message points in the direction of the gdb-attach event that can be set up to issue a halt or "reset init" which will put GDB in a well defined stated upon attach and thus have a robust flash autoprobe.

* 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.

* NOR/core bugfix: restore invariantsDavid Brownell2010-04-151-5/+16
| | | | | | | | | | | | | | | | The The patch labeled "CFI CORE: bug-fix protect single sector" was merged rged without some requested bugfixes. Most significantly it broke invariants in the code, invalidating descriptions and changing the calling convention for underlying drivers. (It (Also wasn't CFI-specific...) Fix that, and Include an update from Antonio Borneo for the degenerate "nothing to do" case, (although that's still in the wrong location. which is presumably why that is it was working in some cases but not all.) src/flash/nor/core.c | 21 ++++++++++++++++----- 1 file changed, 16 insertions(+), 5 deletions(-) Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
