* cfi: fix error handling for protect fnØyvind Harboe2010-05-051-4/+4
| | | | | | No error was propagated. 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
* flash: write_image would fail for certain imagesØyvind Harboe2010-04-291-14/+55
| | | | | | | | | | | Fix a bug where write_image would fail if the sections in the image were not in ascending order. This has previously been fixed in gdb load. Solved by sorting the image sections before running flash write_image erase unlock foo.elf. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* flash: write_image will now pad erase to nearest sectorØyvind Harboe2010-04-291-8/+2
| | | | | | | | | | this is done for unlocking and it is a simple omission that it wasn't done for sectors. The unnerving thing is that nobody has complained about this until now.... Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* 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...)

| | | | | | | | | | | | | jtag_get/set_end_state() is now deprecated. There were lots of places in the code where the end state was unintentionally modified. The big Q is whether there were any places where the intention was to modify the end state. 0.5 is a long way off, so we'll get a fair amount of testing.

* lpc3180: LPC3180(LPC3250) SLC driver implementedrichard vegh2010-03-162-9/+441
| | | | | | | | | | | | | | | | Until this time only basic SLC functionality exists when you want to use SLC to access external nand flash. Basic functionality can be selected with command: lpc3180 select 0 slc It is anyway very slow to write/read to/from nand flash. With the new command, SLC speed improved about 20 times, and hardware ECC info also read/written from/to nand flash OOB area: lpc3180 select 0 slc bulk Speed improvement achieved by using working are in SRAM of the LPC3250 chip and controlling DMA controller to interact between SRAM and SLC peripheral. Here are the patches, and if they are ok than take them. Tested with hitex LPC3250 usb stick. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* image loading: fix problem with offsets > 0x80000000Bradey Honsinger2010-03-161-1/+1
| | | | | | | | | | | | | | | Fixes bug that prevented users from specifying a base address of 0x80000000 or higher in image commands (flash write_image, etm image, xscale trace_image). image.base_address is an offset from the start address contained in the image file (if there is one), or from 0 (for binary files). As a signed 32-bit int, it couldn't be greater than 0x7fffffff, which is a problem when trying to write a binary file to flash above that address. Changing it to a 64-bit long long keeps it as a signed offset, but allows it to cover the entire 32-bit address space. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* cfi: simplify and clearify codeAntonio Borneo2010-03-081-149/+75
| | | | | | | | | | | | | | | | At the end I have added comments /* FIXME: to be removed */ There are 3 lines in which my simplification is not complete due to data dependency with LOG_DEBUG() messages visible in the patch. Such log_debug has been introduced on Jan 22, 2007 with commit 4fc97d3f2726efa147cfdb0c456eace51550e1e3 during development activity in this file/procedure. From my point of view, these logs can be removed, since not part of a consistent flow of information. Alternatively, could be borrowed in the new cfi_send_command(), but this will increase verbosity.

* jtag: jtag_add_ir_scan() now takes a single fieldØyvind Harboe2010-03-081-1/+1
| | | | | | | | In the code a single field was all that was ever used. Makes jtag_add_ir_scan() simpler and leaves more complicated stuff to jtag_add_plain_ir_scan(). Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: retire tap fieldØyvind Harboe2010-03-081-30/+15
| | | | | | | | | | | | | | | | | jtag_add_dr/ir_scan() now takes the tap as the first argument, rather than for each of the fields passed in. The code never exercised the path where there was more than one tap being scanned, who knows if it even worked. This simplifies the implementation and reduces clutter in the calling code. use jtag_add_ir/dr_plain_scan() for more fancy situations. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* CFI: review print of Voltage valuesAntonio Borneo2010-03-061-6/+6
| | | | | | | | | | | | JEDEC standard reports Vpp integer part encoded as 4 bit HEX value. To print it using decimal digits, %u is required. Other voltage values are coded as BCD, so %x is appropriate. Code already prints one nibble at a time, so no need for field width and precision in format string.

* NOR: trim range in flash_driver_protect()David Brownell2010-03-031-0/+57
| | | | | | | | | | | | | | | | | | | | | | When the beginning or end of the specified range of sectors already has the requested protection status, don't ask the flash driver to change those sectors. This will among other things turn command sequences like this into the NOPs one would expect: flash protect_check 0 flash info 0 ... reports everything as unprotected ... flash protect 0 0 1 off That speeds things up (by whatever work was just avoided). Also, with Stellaris (which can't unprotect flash at page level) this can eliminate some undesirable/false error reports. (And finishes fixing a bug currently listed in our bug database...)

* NOR: invalidate cached state on target resumeDavid Brownell2010-03-032-0/+35
| | | | | | | | | | | | | | | | | | | | The NOR infrastructure caches some per-sector state, but it's not used much ... because the cache is not trustworthy. This patch addresses one part of that problem, by ensuring that state cached by NOR drivers gets invalidated once we resume the target -- since targets may then modify sectors. Now if we see sector protection or erase status marked as anything other than "unknown", we should be able to rely on that as being accurate. (That is ... if we assume the drivers initialize and update this state correctly.) Another part of that problem is that the cached state isn't much used (being unreliable, it would have been unsafe). Those issues can be addressed in later patches. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* NOR: stellaris message tweaksDavid Brownell2010-03-031-4/+4
| | | | | | | | | | | | | | | Give a more accurate failure message when trying to unprotect; don't complain about pages being write protected, just say that unprotect is not supported by the hardware ... referencing the new "recover" command, which is the way to achieve that. Likewise, when trying to protect, talk about "pages" (matching hardware doc) not "sectors" (an concept that's alien to these chips). Also make the helptext for the "recover" command mention that it also erases the device. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
