"The target may have entered reset escalation ,Please power cycle the board" when censoring

Hello,everyone

Recently,I have tried to censor the board NXP  MPC5741 ,but I failed.

Before the censor,  the I have read many suggestions and replys between jiri.kral@nxp.com  and other developers ,then i used  censor method is that, use the sofeware  PROGPPCNEXUS ( free starter edition, http://www.pemicro.com/downloads/download_file.cfm?download_id=194),and use the PE Mirco MULTILINK UNIVERSAL together,to program the DCF area ,and censor the board. 

But, when I connect the board by using the  PROGPPCNEXUS ,and downlaod the .pcp files(NXP_MPC5742P_1x32x4k_UTest.pcp),and select S-REC file (S3150040020005AA55AF0000000055AA12340100000CA3S315004002101234567801000004123456780100000862)

and then,I click EM ,failed ,then  click PM ,also failed. Finally  I disconnect the link  between board  and PROGPPCNEXUS.when I click the connect again  on PROGPPCNEXUS ,but it reminder me that "The target may have entered reset escalation ,Please power cycle the board" ,I have tried the method “ lower the debug shift frequency and add 200ms reset delay before connecting to your device in PROG ”,but  it  doesn't work. I also tried the link between PE Mirco MULTILINK UNIVERSAL and  S32DS, also like this. So  please help me:jiri.kral@nxp.com

(1)whether this  method can actually censor the board?

(2)Can you provide detail steps,if this method work? if this method doesn't work, do you have anyother censor methods for NXP MPC 5741?

(3)how can I solve the problem "The target may have entered reset escalation ,Please power cycle the board" ?

thank you very much!

Hi,

As you intentionally censored the board, reset escalation is not your case.

It is just false report from debugger.

I wonder what did you program to DCF records.

In order to successfully censor this micro it is needed just 3 steps withing one reset cycle:

1. Program NVSCI DCF record to first available space in UTEST memory.

   data.set 0x00400308 %QUAD 0x55AA12340100000C ;NVSCI - Censorship Control enabled

2. Program Censorship password (0x1234567812345678)

   data.set 0x00400308 %QUAD 0x1234567801000004 ;NVPWDL                                                        
   data.set 0x00400310 %QUAD 0x1234567801000008 ;NVPWDH   

3. Perform reset

I have posted an article for lauterbach debugger, but the steps are same for any kind of debug device:
