Hi,
Customer has reported that they have 1 unit of LFHP1824-1290 failed at FCT station. We need your help for this analysis. Appreciate your support in this request.
Below are the details of the affected unit:
Part Number : LFHP1824-1290
MPN : LS1046ASE8T1A
Description : IC QORIQ PROCESSOR 4 CORES 780-FCPBGA
Supplier : NXP Semiconductors
Date Code : 2114
Location on Board : U83
Board S/N : SG17KPK013
Fail Station : FCT
Failure Description : Able to load RCW and Uboot, but unable to load OS and boot further.
RCW – Reset configuration word.
Reset Configuration Word (RCW):
00000000: 0e150012 0d000000 00000000 00000000
00000010: 33335577 0000401e 40000000 c1000000
00000020: 00000000 05000100 00000000 00428ffd
00000030: 00004104 24101200 00000096 00000001
Read existing content (codes) – store for future reference:
No issue with the code/flash, as the board able to pass all flash partition and functionalities check with new processor.
Reflash and reverify the content (code):
Same code/flash works on a new processor, which means no issue with the code or flash.
Reverify board functionality:
Board functionality good with new processor
Like at what voltage, what temperature, how to translate that the RCW message into failure description.
=> voltage - 3.3V, 1.8V,1.2V
=> room temp
=> Customer: I mentioned RCW just to say that Processor has crossed the initial milestone of booting up using the Uboot from the SPI flash. it got hanged while booting up to the OS from the emmc interface. RCW itself don’t have an error code within it. Need to get NXP to perform their full chip level test and confirm no issues on their side.
