| * mips: illustrates how to improve performanceØyvind Harboe2011-04-014-14/+21
| | | | | | | | | | | | | | Do not require unecessary roundtrips for clocking out data. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
| * types: write memory now uses constØyvind Harboe2011-04-0130-85/+85
| | | | | | | | Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
| * mips: delete kludgy code that modifies data sent to write_memory()Øyvind Harboe2011-03-311-1/+16
| | | | | | | | | | | | | | | | Could this cause confusion as data sent to write would be flipped and then if the caller subsequently used the data, e.g. a compare mismatch might happen? Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
| * startup: fix bugs in cleanup upon errors during startupØyvind Harboe2011-03-311-26/+33
| | | | | | | | | | | | Importantly adapter cleanup will now happen upon startup failure. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

| * mips: fix mips_ejtag_set_instr error handlingØyvind Harboe2011-03-312-14/+10
| | | | | | | | | | | | this fn does not fail, it queues data. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* | mips: fix gaffe in previous commitØyvind Harboe2011-04-011-1/+4
|/ | | | | | | | accidentally invoked return jtag_execute_queue() in the middle of a fn. Hmm.... I would have expected gcc or at least lint to catch this. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

| | | | Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* target: add -dbgbase option to target configurationØyvind Harboe2011-03-312-0/+23
| | | | | | | | | Really a Cortex-A specific option, but there is no system in place to support target specific options currently and there has been no need for such a system until now. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* at91sam3: Modified cidr comparisson to ignore version bitsOlivier Schonken2011-03-301-1/+2
| | | | | | production processor versions increment, thus the version bits should be ignored for future proofing. e.g. Engineering sample version == 0x00, production version 0x01
* Clarify LPC32XX address cycles messageAlexandre Pereira da Silva2011-03-301-1/+1
| | | | | | | | | Hi, This is a more descriptive message about LPC32XX error, when the nand chip needs 5 address cycles. Thanks.
* Add Micron 2GiB nandAlexandre Pereira da Silva2011-03-301-0/+2
| | | | | | | | Hi, This will add support for a new nand chip device. Thanks.
* bugfix for step <address> mips_m4kAndrew Lyon2011-03-291-0/+4
| | | | | | | | | The patch below fixes step <address> on mips_m4k. Spencer Oliver <spen@spen-soft.co.uk>: The current code is used on all other arch's - is there a underlying issue with those aswell ?

* zy1000: fix bug in ir scan handlingØyvind Harboe2011-03-211-0/+5
| | | | | | | set cur_instr to BYPASS as optimisation code will rely on checking the cached value. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* dsp563xx_once: fix warning and potential bugØyvind Harboe2011-03-201-1/+1
| | | | | | | | I don't think dsp563xx_once_read_register() would ever be called with len==0, but it would have been broken in that case. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

* target: allow targets to override memory alignmentMathias K2011-03-172-4/+32
| | | | | Targets can implement read/write_buffer to handle alignment.
* SYS_WRITE0 fixJohn and Tina Peterson2011-03-171-1/+1
| | | | | | Problem is, trying to print "Hello, world!\n" just prints endless H's, because r1 is never incremented. One way to fix it would be to add a "++" after "r1".
* Fix a bunch of typos.Uwe Hermann2011-03-1713-14/+14
| | | | | | | | Fix a bunch of typos. Most are in code comments, so nothing should break. UNKOWN_COMMAND and CMD_UNKOWN are not used elsewhere, so correcting the spelling should also not break anything.

* zy1000: fix JTAG over TCP/IP performance problemØyvind Harboe2011-03-151-8/+11
| | | | | | | only flush write queue just before waiting for more data, rather than when fetching more data from the buffer. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* zy1000: fix incorrect usage of jtag_sleep()Øyvind Harboe2011-03-151-1/+2
| | | | | | | | Found by inspection: the correct thing in the context is to use usleep() rather than jtag_sleep(). Relates to JTAG over TCP/IP only. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
* jtag: clean up jtag_sleep, handle short sleeps correctly via usleepØyvind Harboe2011-03-151-1/+8
| | | | | | | | | | | short sleeps are handled via usleep, longer sleeps we round up to nearest ms. There was a bug in jtag_sleep() in that it would round *down* to nearest ms, thus making all <1ms sleeps 0. Found by inspection rather than symptom.

* ft2232: fix possible read buffer overflowMathias K2011-02-241-3/+17
| | | | | | | | This patch fix a possible read buffer overflow in ft2232_execute_queue. Also the correct read queue size for libftdi and libftd2xx was added and and tested. In function ft2232_write a uninitialized value was initialized because we don't know if this value was set in the ftdi api call.

* dsp563xx: rudimentary gdb supportMathias K2011-02-211-206/+477
| | | | | | | | | | | This patch add rudimentary gdb support. The gdb register list order is corrected. All registers are now 32bit width. Events are send to signalize gdb the current target status. Resume and step function was corrected to consider a modified pc register. Read/write memory now support L memory type, this means a memory with alternating y/x memory words. The memspace variable, used by gdb, is now observed before a default memory access is initiated. Dummy functions for breakpoint and watchpoint are added.
