Codewarrior TAP ccs removed

[mihai_tudose89]

Hello all,

I intend to use a Codewarrior TAP to debug an existing system featurin MPC5200.

First, I want to connect the TAP via ethernet, as USB drivers sometimes make my computer stuck (on Windows 10) and I had no succes with them.

Could you please provide help with the following questions:

1. To my understanding, I do not need any drivers if I will connect the TAP through ethernet. USB will be used only for power.

2. Accesing the telnet interface of the TAP with putty works. However, when I type:

core> ccs
(removed)

core> ccs version
/mnt/flash/ccs/bin/coreprompt/ccs: exec: line 67: /mnt/flash/ccs/bin/coreprompt/ccs --help: not found

I have reflashed firmware but with no succes.

Can you please tell if this is normal? 

Thank you and best regards,

Mihai

Thank you for your quick answers, @petervlna 

1. I used USB only for power from a wall adapter, not from the USB port of a computer. It should be able to supply the required 500mA, as described in the user's guide.

However, I can try the USB connection from the computer also on a Windows XP system. To my understanding, the drivers might not support Windows 10.

I am open to any of the ethernet / USB options, or a combination of them. I only want to get it working, get it detected with findcc etaps or utaps in ccs console.

2. Could you please recommend a method to restore the firmware package/CCS inside the TAP?

If there are multiple builds of the firmware depending on the target families, I would be interested in the one which includes MPC5200. Hopefully these builds are available somewhere.

I could also dissasemble the unit and check internal hardware/interfaces if needed.

Best regards,

Mihai

Hello,

1. To my understanding, I do not need any drivers if I will connect the TAP through ethernet. USB will be used only for power.

The TAP itself is USB powered, but the official guide also states that if you only plan to use Ethernet communications, the TAP can be powered from the external power supply provided with the unit, rather than depending on a USB connection to the PC.

Can you please tell if this is normal?

No — this is not normal behavior, and it points to an issue with the CCS installation inside the TAP.

mnt/flash/ccs/bin/coreprompt/ccs --help: not found

means one of these is happening:

The CCS binary is missing or corrupted

• The script exists (ccs launcher), but the actual executable it calls is not there
• Very typical after bad firmware flash or incomplete image

Wrong firmware package

• CodeWarrior TAP firmware has different builds (target families / CCS versions)
• If wrong image is used → CCS part may not be included or mismatched

Broken internal path / environment

• The script (ccs) tries to call itself with parameters (--help) and fails
• This often happens when:
  • symbolic links are broken
  • filesystem is partially corrupted

Best regards,

Peter
