In Windows XP: make sure to turn off the parallel port plug and play scanning "feature". This will yield what looks like sporatic communications. If the cable is not marked with the IEEE text, then it is not compliant. You must reboot your PC after this setting to take effect. Make sure to turn off any applications which may be trying to access the printer port such as a Print Manager before running software to debug with LPT-to-JTAG interface.

Also beware that some laptops, in particular some of the IBM Thinkpads, do not implement a standard parallel port even though they claim they do. If you encounter this problem on a laptop and have access to a desktop machine, it is best to try the experiment on the desktop in order to rule out other issues.

Fragen: 1. Dies Angabe bezieht sich auf das Modul mit Vollausbau, d. Alle Clocks der notwendigen Peripherie waren damit eingeschaltet. Kommen jetzt noch Aktionen hinzu wie z.

Stromaufnahme Ethernet kann nur durch Vergleich zweier Boards einmal mit bzw. Habe ich zwei dieser Boards, kann ich mal nachmessen Werde versuchen, diese Messungen mal nachzuholen Der Unterschied hier liegt im Bereich von ca. Stromaufnahme siehe oben! By default, jumper J connects this port to the Ethernet Controller.

For additional information regarding jumper settings for J, please refer to the Hardware Manual under Section 3. Make sure that the external flash is erased before programming it to iFlash. If you are using an old Phytec Spectrum CD, go to our website to obtain the latest blinky.

Those are GPIO registers. Also, in serial. Check if there is anything in the external flash that modifies the LPC controller configuration in a way that does not allow any JTAG communication. Press both buttons; release the reset button and then the boot button a few seconds later. There is an Ethernet limitation to the LPC which stems from the Carrier Board and is only present when connecting at Mbit speed.

At this baud rate, the auto-negotiation phase will not correctly be finished so there will be no error free transmission. However, the problem will not occur at 10Mbit speed. This limitation is caused by the length of the signal traces for the Ethernet lines, as well as the way the signal lines are routed.

Unfortunately, the LPC has inherited this limitation. If you design your own carrier board, be sure that these signal traces are straight and as short as possible. There are different targets within each of the demo examples. You may have something stuck in iFlash that prevents another program in xFlash from booting. I suggest you bring the system into bootloader mode by pushing Reset and Boot push-buttons simultaneously. What value do we need to assign to acknowledge an interrupt?

Shortly before ending the ISR this register should be written in order to execute a sort of End of Interrupt. Since Philips didn't specify which value one should write to this register it doesn't matter what you write. The only important thing is that the register is being written. It is possible to write "0" to this register, no matter from which ISR initiated the write access. I attempt to measure the power consumption of the LPC processor, but I have not been able to find a location where I can isolate the 3.

With some effort and a few module modifications it is possible to measure the 1. You would have to desolder pins 1 and 3 on Q and lift these pins off the solder pad. You then measure the current via J In order to figure out the current draw of the 3.

Is there a way to erase the flash without using the Philips flash utility? I am using the KEIL software development tool. Section 3. The quartz frequency of the external clock source is 10 MHz. We use a Jauch quartz crystal from their JXE75 series. For more information, please refer to Section 14 of the Hardware Manual. The manual says: "P10" which I take to mean port 1, bit 0 and the schematic says "P" which I take to mean port 0, bit Please refer to Section 3 of the Hardware Manual for more information.

Please refer to Section 4. Section 17 of the Hardware Manual describes the details on the Ethernet interface. There are no RS transceivers for these additional modem control signals. Only Rx and Tx go through an on-board RS transceiver. If you wish to use these signals you need to route them through such an transceiver somewhere on your carrier board or an expansion board. You should NOT attempt to connect these jumpers and use these signals without proper level conversion.

While testing this in a debugger environment, please don't single-step through these steps. I need to use both SPI interfaces along with the Ethernet controller in my application. You should be able to configure the Ethernet controller to retrieve the specific configuration data elsewhere.

This would likely cause a software modification. Are these ports being used for some other purposes? There are two jumpers which may ground signals P0. However, the default settings of jumper J which connects to signal P0. Hence the signal level at both pins should be 3. Therefore, the signals should not be grounded. There are no other connections of these signals to any other components on the phyCORE module.

It is possible that you could have changed the default settings of the signal direction, given that P0. The connection of the Reset pin to the 12V is a feature of the Flash-device.

See section 3. See figure 6 or figure 35 for Jumper location. The side that has only a small black square is where pin 1 is. The "solid" line is pin 3. R is not to depopulate because it is not placed in respect of a 32bit external data bus. Depopulating of the external memory is not necessary because the memory will be inactive if the CS signals are not active. Ensure that the CS signal lines are inactive for all populated external devices.

If this is not possible the external devices have to be removed. First, be sure that there is nothing in external flash if you are trying to program and execute from internal flash.

If you have a program in both internal and external flash, the program in external flash will always execute upon a reset not the code in internal flash. To erase the external flash, select the "External Flash - Erase Only" from the target pull down menu Refer to Section 3.

Next, disable External Flash from booting by modifying the system startup configuration. This can be done by removing some resistors on the module. The configuration options for internal and external RAM are created manually; they are not default created when making a new project. This has to be configured manually. For more information on configuring the target settings, please refer to the QuickStart in Section 3.

The pull ups are not on the controller port side. The function of the pull up resistors is to ensure a proper high level with 3. This also improves the slew rate of the ports.

Where can I find information about the mapping between the two pin and the row patch area? You can access the signals with the Port Pin label and number at the Molex connectors. There are bootstrapping pins to enable or disable ETM.

Is the P1. This pin has an internal pull-up, so if there is no external pull-down then ETM will be disabled. Similarly, is P1. The special settings for this are described on the schematic of the PTA There are four DB9 connectors on the board.

Which two are the serial ports and which two are the CAN bus ports? Please refer to Section AMP
