Any major differences between CW USB TAP and CW TAP?

[mariochan]

Hi Tech support,

I previously purchased CW USB TAP.

Probe Tip:  Power Architecture JTAG/COP

PC window 7 64 bit.

PC installed Power Architecture 8.8

Target PCB with the processor: MPC8358ECVRAGDGA

It worked. Typed "findcc utaps" @ CCS, it shows my CW USB TAP serial number.

I am able to "erase" in flash programmer.

Problem:

I purchased CW TAP (Supports USB and Ethernet)  for mass production.

PC window 7 64 bit. (Same)

PC installed Power Architecture 8.8 (Same)

Target PCB with the processor: MPC8358ECVRAGDGA (Same)

It failed. Typed "findcc utaps" or "findcc ethaps", etc @ CCS. It does not show anything.

I am NOT able to "erase" in flash programmer, it shows check JTAG clock speed.

i have set netparam as following:

core> netparam

ethernet_address        = 00:04:9F:03:9B:ED

bootconfig              = static:FSL039BED

static_ip_address       = 169.254.3.4

static_dns_server       = <none>

static_hosts            = <none>

static_routes           = <none>

PC directly connects to CW TAP.

PC's ip= 169.254.3.2

PC's subnet mask= 255.255.0.0

Please advise.

The correct command for finding cwtap in ccs is: findcc cwtaps. Because you are using an old version of CW, it is possible that your ccs version to not support cwtap. Here is a document showing how to update ccs for cwtap usage (it is  not for your version of CW, but is applicable).

Hi Adrian,

Which version should i use for supporting cwtap?

Current version is Power Architecture 8.8.

My company also has version Power Architecture 10.0.2. Does it support cwtap?

If not, which version should i get?

Thanks for the support.

Hi Mario,

The latest version of CodeWarrior is 10.5, and this is the version recommended. But, you can follow the steps from the doc, and use a version of ccs that supports cwtap in your CW 8.8 version.

Also, you can check if your PA 10.0.2 supports cwtap, by opening ccs and probe the command: findcc cwtaps.
