Connect to an ST40 performance simulator little endian, cycle connectsh4psimle accurate. Connect to an ST40 performance simulator big endian, cycle connectsh4psimbe accurate. Table 13 lists the SuperH simulator configuration commands.

Only one configuration command can be specified and must be specified as a string that is, enclosed within double quotes. Simulator configuration commands Command Description. Default is 1 cycle. Enable mode is 1 or disable mode is 0 a simulated serial port. Each of these commands invoke a suitable connect command see Section 1. A parameter of the connect command is the GDB user command to invoke after connecting to the target. This command configures the target and is defined in the GDB command script file board.

For example, the GDB command script file mb The connection command variants exist to support the different se-mode variants. To change the default behavior controlled by these convenience variables, they need to be set before connecting to a target.

Note: The board or SoC they control is encoded into the convenience variable name. Global convenience variables Convenience variable Default value Behavior. The methods are provided in the form of GDB command scripts. Table 17 lists the connection commands defined by the GDB command script file sh4targets-targetpack. The configuration commands must be specified as a string that is, enclosed within double quotes if they contain spaces and may be combined using a space to separate each command.

Base address for the level 2 cache configuration registers. See alsoSection 2. Each component of the TargetString is separated by a colon. The parameters can be separated either by commas or spaces. If the parameters are separated by spaces then the TargetString must be enclosed within double quotes. Connecting to a target with a TargetString that includes this parameter prevents the target from being configured by the ST TargetPack, allowing a GDB command script to be used instead.

To perform this type of connection, the user can define their own user command. For example, a GDB command script that re-configures the system clocks may need to set the TCK frequency to a speed where this operation is safe.

There are also restrictions applicable to specific hardware that must be taken into account when writing GDB command scripts that change the ST40 core clock frequency.

The end result is that the default frequency of TCK If using version R1. See Table Used by the mb41stbbypass command. Used by the mb41stbstmmx command. Used by the mbstbbypass command. Used by the mbstbstmmx command. Used by the mbbypass command. Used by the mbstmmx command. If the. Several versions of the command are defined. Used when attaching to a running or stopped target. These commands do not reconfigure the target, instead they allow the user to take control of a running target, see Table The attach commands do not perform any target-specific customization unlike the target-specific connection commands, see Section 1.

As a result, no GDB convenience variables are defined for the memory-mapped configuration registers. To define these convenience variables, invoke the appropriate SoC command for the target see Section 2.

For convenience, the attach command and SoC command can be combined by the user into a new GDB user command to provide a target-specific attach command. For example: define attach-mb source register A target is stopped in debug mode if the target was being debugged when disconnected with the ondisconnect mode set to none the default. Note: The attach commands defined by sh4targets-attach-debug. The default is 10 MHz and the maximum is 25 MHz.

Use help linkspeed to display linkspeed the complete list of link speeds. Not compatible with the STMC2. This is the same as the linkspeed configuration command.

Set the action to perform on disconnecting from the target. This command is retained only for backward compatibility and may be removed from future releases. Set a configuration command 1 after connecting to a target. Set the reporting level of the STMC diagnostic messages. Use help use-watchpoint-access-size to display the complete list of access size checking options, use-watchpoint-access-size see the ST40 Micro Toolset User Manual for further details.

This is the same as the useaccesssize configuration command 1. Note: Not all configuration commands may be usefully set after connecting to a target. Table lists the equivalent stmcconfigure commands for the target commands listed in Table The subcommands supported by the jtag command are listed in Table Specify the TCK signal sequence. See Section A. Specify the TDO signal sequence.

The asebrk, nrst, ntrst, tck, tdi, tdo, tms, triggerout and stmmx signal subcommands of the jtag command may be combined with each other using space separation whereas the mode and help subcommands may not be combined with any other jtag subcommand. The syntax of signal is described in Section A.

Note: 1 The stmmx signal subcommand only has an effect when the jtagpinout configuration command has been set to stmmx. All further manual control of the TAP is disabled until the mode is normal changed to one of the other modes listed in this table. This is the default mode.

Set the TAP to manual control. In manual mode, the TCK signal has to be explicitly specified through the tck signal subcommand unlike the singleshot and continuous modes. The same as manual mode except that the TCK signal is automatically clocked 1 cycle for each signal specified by the jtag command.

The tck signal subcommand is ignored in this mode. Note: The TCK clock speed in the singleshot and continuous modes is determined by the debug link speed as set by the linkspeed configuration command see Table 7: Common STMC configuration commands on page 15 or the linkspeed user command. The TCK clock speed in manual mode is determined by the signal sequence specified by the tck subcommand and the speed at which the ST Micro Connect can transmit the signal up to a maximum of the debug link speed.

New Topic. Now we are interested on JTAG. We need to copy the NAND out from the box. I need to do it very simple, with LPT port and a few resistors. Is for it possible to use this schema? If is this circuit is possible to use, so what software is good for it on Windows? What is possible to do with the software? Some manual? I'm not really sure, if it is possible by us, to connect the wires so, like on the picture. Our JTAG port has 20pins.

The first row of 10 pin is fully connected to GND. The second 10 pins have I measured with a digital voltmeter, so I'm not really sure what is what. Interesting is, that the last pin is connected to nothing.

Last Edit: 8 years, 10 months ago by joseff. Reply Quote. I've tried to no avail! The JTAG connector is not numbered as shown in your post. One row has odd numbers and the other row even numbers. So the pins connected to ground are numbered starting with 2 up to 20 The other side with the JTAG connexions is numbered starting with 1 up to What you number pin 2 is likely pin 17 which resets the box when connected to ground.

I can start a session but that session is always "shutdown by peer". I've tried with various ports , , , However I've found other interesting information in the MB and MB eval boards docs.

There is even a full schematic on the Stbref board where I've found interesting information on how to switch to another boot mode. This allows the boot to switch in boot mode
