2013-04-02pic32mx: 0 wait state optionSalvador Arroyo1-3/+2
By default pic32mx starts after any reset with 1 wait state for RAM access/exec. It can be changed to 0 wait states by clearing the BMXWSDRM bit (bit 6) in BMXCON register. With 0 wait states near doubles the execution speed. CRC check sum can be done much faster increasing verify_image speed. Fast data transfer also works with a bit higher scan rate, up to 1500 Khz. This option can be set at any time with mww 0xbf882004 0x40 or cleared with mww 0xbf882008 0x40. Some numbers for FTDI/HS with current devel code and a elf file: Core clock / wait states verify_image speed ------------------------------------|------------------------------ 4 Mhz / 1 21 KiB/s 4 Mhz / 0 36 KiB/s 8 Mhz / 1 37 KiB/s 8 Mhz / 0 57 KiB/s Change-Id: I4092ad0f3753f72f77108718d0ed3a3ab84e3b23 Signed-off-by: Salvador Arroyo <sarroyofdez@yahoo.es> Reviewed-on: http://openocd.zylin.com/1141 Tested-by: jenkins Reviewed-by: Spencer Oliver <spen@spen-soft.co.uk> Reviewed-by: Xiaofan <xiaofanc@gmail.com>
2012-11-16Pic32mx.cfg: Change system clock to 8Mhz after reset-init.Salvador Arroyo1-0/+14
As for openocd 0.6.0-rc2 the function mips32_pracc_fastdata_xfer() should now work at a scan frequency up to 1200Khz. Mainly usefull to increase programming speed. Also verify_image should be slightly faster.

2011-10-30config files: Drop incorrect comments.Uwe Hermann1-1/+0
There are many "force an error till we get a good number" comments in target/board files. This refers to the use-case where a config script sets _CPUTAPID to 0xffffffff (which presumely gets overridden later): if { [info exists CPUTAPID ] } { set _CPUTAPID $CPUTAPID } else { # Force an error until we get a good number. set _CPUTAPID 0xffffffff } However, the same comment was also copy-pasted in many files which do _not_ set _CPUTAPID to 0xffffffff, where the comment doesn't make any sense at all. Drop those comments. Also, add one missing comment, and fix small whitespace and grammar issues.

Globally rename "jtag_nsrst_delay" as "adapter_nsrst_delay", and move it out of the "jtag" command group ... it needs to be used with non-JTAG transports Includes a migration aid (in jtag/startup.tcl) so that old user scripts won't break.

Add flash algorithm support for the PIC32MX. Still a few things todo but this dramatically decreases the programing time, eg. approx programming for 2.5k test file. - without fastload: 60secs - with fastload: 45secs - with fastload and algorithm: 2secs.

2009-11-08target.cfg: remove "-work-area-virt 0"David Brownell1-1/+1
The semantics of "-work-area-virt 0" (or phys) changed with the patch to require specifying physical or virtrual work area addresses. Specifying zero was previously a NOP. Now it means that address zero is valid. This patch addresses three related issues: - MMU-less processors should never specify work-area-virt; remove those specifications. Such processors include ARM7TDMI, Cortex-M3, and ARM966. - MMU-equipped processors *can* specify work-area-virt... but zero won't be appropriate, except in mischievous contexts (which hide null pointer exceptions). Remove those specs from those processors too. If any of those mappings is valid, someone will need to submit a patch adding it ... along with a comment saying what OS provides the mapping, and in which context. Example, say "works with Linux 2.6.30+, in kernel mode". (Note that ARM Linux doesn't map kernel memory to zero ...) - Clarify docs on that "-virt" and other work area stuff. Seems to me work-area-virt is quite problematic; not every operating system provides such static mappings; if they do, they're not in every MMU context...
