For example, the Freescale i.MX31 has a SDMA (Smart DMA) with a JTAG TAP; that TAP should be named sdma. - --irlen NUMBER -The length in bits of the instruction register, such as 4 or 5 bits. - -Target ------- -http://openocd.sourceforge.net/doc/html/CPU-Configuration.html#CPU-Configuration - - target create target_name type configparams... - $target_name configure configparams... - - -chain-position dotted.name – names the TAP used to access this target. - -endian (big|little) – specifies whether the CPU uses big or little endian conventions - -event event_name event_body – See Target Events. Note that this updates a list of named event handlers. Calling this twice with two different event names assigns two different handlers, but calling it twice with the same event name assigns only one handler. - -work-area-backup (0|1) – says whether the work area gets backed up; by default, it is not backed up. When possible, use a working_area that doesn't need to be backed up, since performing a backup slows down operations. For example, the beginning of an SRAM block is likely to be used by most build systems, but the end is often unused. - -work-area-size size – specify work are size, in bytes. The same size applies regardless of whether its physical or virtual address is being used. - -work-area-phys address – set the work area base address to be used when no MMU is active. - -work-area-virt address – set the work area base address to be used when an MMU is active. Do not specify a value for this except on targets with an MMU. The value should normally correspond to a static mapping for the -work-area-phys address, set up by the current operating system. - -rtos rtos_type – enable rtos support for target, rtos_type can be one of auto|eCos|ThreadX| FreeRTOS|linux|ChibiOS|embKernel See RTOS Support. - -Flash ------ -http://openocd.sourceforge.net/doc/html/Flash-Commands.html#norconfiguration - - flash bank name driver base size chip_width bus_width target [driver_options] - - name ... may be used to reference the flash bank in other flash commands.
