Hi,

Can you check the 14 pins JTAG connector and JTAG signal assignment? The red line of the 14 pins flat cable is pin1. BTW, the MC56F8335 does not have internal crystal, you have to connect external clock source or crystal.

Hi xiangjun,

The MC56F8335 works well since there already is firmware in it , and the performance is ok,

the pin assignment is also ok, since the connector will not allow to insert if pin not match.

Hi, Emily,

Pls try to set the USBTAP in CCS, pls run the instruction:

delete all

update utap xxxxxxx

The xxxxxx is the unmber index on the back of USBTAP device, for example, my USBTAP number is 07350003

Hope it can fix your issue.

Emily,

This question had been asked before: what Windows version on your pc? The classic USB TAP doesn't work with Windows 7 and you need to update the CCS folder (under the IDE tool installation) as the Tech had suggested in previous post.

Hi brian:

    I have tried to update the CCS folder on Win7(which  have been described  in above chat history with Xiangjun) ,

and also try to use this tool on WinXP, both failed.

 i apply it on another board with same DSP and it shows same error message

and the Run/Pause LED on the probe is always red.

i suspect there is something wrong with the physical probe: Once USB tap

but i donn't know how to verify it.could you help me.

thanks.

Hi Emily,

It seems the USB driver was loaded OK. Let's try with the 56800E Flash Programmer software to load an S-record file to the target -- this is simpler than run a debug within the IDE.

1. connect the usb tap to the target board and to pc

2. power up the target

3. run 56800E Flash Programmer and choose a working s-record file, then click program to load the target. Below is how the TAP led lights showing:

• USB cable connected: TX/RX flashing green light about 1HZ
• Applied power to the board: the TX/RX flashing as above
• After clicking the Program, the TX/RX light flashing rapidly between green/yellow, and the Run/Pause to red.
• Finished loading and processor runs: run/pause turns green and tx/rx flashing 1hz

If this works then the hardware is OK, and next step is to find out why IDE debug not working with TAP.

hi brian:

    1. connect the usb tap to the target board and to pc:

         the TXRX led blink in red;

     2.Applied power to the board:

        the TXRX led blink in red;

     3. After clicking the Program, 

         the TXRX led blink in yellow or green and the run/pause is red.and at the same time

report error message as below:

Hi,

After you connect the USBtap, can the PC recongnize the USBTAP?

This is the screenshot on my PC after I connect the USBTAP device?

If you can not, the USBTAP may break down or the USBTAP driver has issue. In the case, pls try to install the USB driver ans see the ccs_drivers_installation_help.txt located at:

C:\Program Files (x86)\Freescale\CodeWarrior for DSC56800E v8.3\ccs\drivers

Hi xiangjun:

    YES, please refer to the screen snap which i have send to you in above history:

Hi, Emily,

Regarding your question, firstly, do you use Win7 OS, if you use it, you have to download an4338SW, and unzip it.

Then replace the CCS directory of the Flash programmer tools with the unzipped CCS directory of an4338SW.

If you do not use Win7, it is another story.

Firstly, do you use EVM board or your own target board, if you use EVM board, because there is on-board parallel port, there is a jumper called "CC DIS", you have to close the jumper.

Secondly, you should download xxx.elf.s which is generated by CW for DSP56800E tools based on your application, this is the S recorder file.

Thirdly, pls use correct configuration file which is loacted at:C:\Program Files (x86)\Freescale\CodeWarrior for DSC56800E v8.3\M56800E Support\initialization

Hope it can help you

and the error message is still exist as below:

error log as below:

could you help , thanks.

[xiangjun_rong]

Hi,

Can you use CW for DSP56800E to download code and debug? If you can not, I suppose your target board has issue, pls check power/gnd pins, crystal, JTAG signals.
