Use CW 10.6 to debug SPC5668E

[jonasa]

Hello,

I'm looking for a good alternative to debug the PowerPC microcontroller SPC5668E. One alternative would be to use CW 10.6 together with P&E Micro's debug probe (U-MULTILINK or U-MULTILINK-FX).

Does anyone have experience with this setup?

I would also like to know if an 14-Pin Berg to 38-Pin Mictor Adaptor (like http://www.pemicro.com/products/product_viewDetails.cfm?product_id=159  ) is included if I buy U-MULTILINK or U-MULTILINK-FX? I have a 38-pin mictor on the PCB.

What debug features are included in CW 10.6?

Can I set a breakpoint while the programming is running?

Can I get live update on variables?

Callstack?

Can I change variables etc.?

Write to HW registers?

Is trace included?

Can I program the device with CW 10.6?

Kind regards,

Jonas

Hello Jonas

U-MULTILINK and U-MULTILINK-FX only has 14-pin JTAG interface, and the emulators supported by CodeWarrior does not has MICTOR Connector.

The 14-pin JTAG connector does not allow for trace information.

The MICTOR connector allows for full real-time trace to be supported, either program trace, ownership trace, or data trace.

The features that 14-pin JTAG Connecter supports:

- Full run control capabilities:

     = setting breakpoints

     = modifying memory

     = step program execution

- Nexus Read Write Access - capability to read and modify memory while

target is running

- Access to last 8 branches taken (no instruction counts)

38-pin MICTOR (Full Nexus)

- All features available with 14-pin JTAG

- Program Trace - via branch trace with instruction counts

- Data Trace - Reads, Writes, or Reads and Writes

- Ownership Trace - if core OTR register is used to signal changes in

tasks/owners

- Watchpoint Messaging/Trace  

I would suggest to contact P&E to get to know whether the above functionalities work well after the JTAG signal is converted by Mictor Adaptor.

Best Regards

Ok so NXP don't sell the adaptor that I refer to (http://www.pemicro.com/products/product_viewDetails.cfm?product_id=159)?

Is the microcontroller SPC5668E supported? I can't find it in the supported devices list. I can see that SPC5668G is supported.

Kind regards,
