Mpc860 debug issue

[ravadasrikanth3]

i'm using MPC860 in my board which is not entering into debug suddenly, which is working previous.

The Transfer Error Acknowledgment(TEA) pin is toggling which is indication for BUS ERROR when trying to enter into debug.

can you help us how to solve this issue.

i checked power supply,clock,resets everything is fine.

i have another two boards with same configuration which are working,

But this board stopped working suddenly

If your have CodeWarrior TAP, please download and install CodeWarrior 8.8 for Power Architecture and Patch 8.8.6 from https://www.nxp.com/design/software/development-software/codewarrior-development-tools/codewarrior-n...

Patch 8.8.6 is used to install CodeWarrior TAP CCS USB driver.

Please create a bareboard project for MPC860 demo board from File->New->EPPC New Project Wizard, then try whether this project can connect to the target board successfully.

Please enable CCS log from Edit->Debug Version Settings->Remote Debug->Edit Connection->Enable logging, then connect to the target, and send the ccs log to me to do more investigation?

Hi yiping,

I'm doing with  the bare board project only but still it is not entering into debug.

i have another board which is working.

The only difference i observed when i'm trying to enter into debug the BUS Error pin (TEA) is toggling.

Can you just tell us what causes this pin to Toggle.

I tried all the possibilities by created new project,new code warrior usbtap,new CODE WARRIOR tool.

this board worked previously but it stopped working.

Here is the CCS log.

[yipingwang]

I didn't find error in your CCS log.

Would you please attach CCS logs for both problem and good boards?

[ravadasrikanth3]

Can you just tell us what causes TEA pin to Toggle when entering into debug.

whether it maybe of address line issue or external memory access issue?

[yipingwang]

TEA is generated by bus monitor timer, as a result of bus timeout. By "bus timeout" I mean the following situation: the bus master initiates a transaction on the bus, but this transaction is not finished within reasonable time. "Not finished" means no transfer acknowledge asserted by bus slave. If no transfer acknowledge asserted within reasonable time, than bus timeout expires and bus monitor generated "transfer error acknowledge" (or TEA). This TEA causes machine check.

I can not say precisely, why TEA is asserted in your case, but usually the reason of TEA is an attempt to access to incorrect memory address (not assigned to any memory controller).
