Dear All,

My MPC5777C Version is 3N45H and XOSC frequency is 40MHz,Core Clock is 264MHz.

I tried to MPC5777C STCU2 Setting refer to AN5288. AN5288 is attached this article.


Question 1 : I applied "MPC5777C_off-line_40MHzXOSC_PLL50MHz_3N45H.cmm" through Trace32. (Run batchfile)

Then I can see DCF configuration at 0x400300 address.. It looks fine.

But My application doesn't running well...

As you know, I asserted a Power-up reset for start of Off-line BIST.

But My hardwared has been invoked running reset continuously.

So I tried attach via Trace32, Then I can see STCU Registers.. The half of LBIST and MBIST Test results are success and passed, but remain test results are failed or ongoing status.


So I want to know that I have to more working for the STCU setting or MPC5777C_off-line_40MHzXOSC_PLL50MHz_3N45H.cmm includes some kind of bug.


Overall, Please let me know how can I STCU, especially off-line test with my hardware.


Question 2 : Can I re-write UTEST area which is stored DCF? When I execute "MPC5777C_off-line_40MHzXOSC_PLL50MHz_3N45H.cmm" file again, There are flash related error..

I mean I want to modify STCU registers for optimization of STCU setting. If UTEST area is writable only one time, I have to find a optimized register seting with manual and xls file? I don't belive it...


Best regards.
