SPC56AP54L3 write problem

[tonyoa78]

Hello!

Anybody read and write without problem SPC56AP54L3 mcu?
I used UPA after carprotool.
Reading was ok, same lot of.
After write my dump into ecu and verify was not ok.
Wrong.
I thought write back original dump but problem is same:
verify not ok, ecu not working.
Anything idee?
This is a VW ecu by Continental

Thanks.

just write clear file and do not verify instead hit read!

see what results you get.

regards

slick

p.s launch clears crash on this with a hit of a button?!

[tonyoa78]

I have checked back writting and this is total other and ecu not working!
Why I can not write back good original crash dump?

Did you see if all the points are correctly connected or if there is welding paste that is bridging at the time of writing?

[Andresolivares]

Would you be so kind as to detail the connection points please

[slick_dick]

correct has to be connection issues

I had 2017 honda crv 77960-TLA-A240-M4,with SPC56AP54
used upa-s
read as SPC56AP54-tried to write-lots off errors
to write used option list as-SPC560P34 3.3V-(data flash only)-writing speed slow-but no errors!!!
verify as SPC56AP54-ok

Hello!

Solution:
unfortunately my ecu has broken down more or less.
This can repair but need to codeflash0 and codeflash1 dump.
For everybody:
UPA has a bug at SPC56AP54L3 mcu.
Problem is known. Need to newer software version.
So far: anybody use not at this mcu version!!!!!!
Only after fixed version! Later.

Any body has codeflash0, codeflash1, dataflash dumps?

I had same problem, XprogM didnt conect, VVDI readed OK but writed with errors not verification passed, the trick was Selecting MCU/ SPC56AP54L5 it writes at lower speed. Now micro baks to life again with cleared file. Thanks

Same problem with Honda Accord 77960-T2F-A020-M4 - SPC56AP54L3, after write back file, data structure change dramatically.
No matter what I do, data is different.

I have the same problem as well, What programmer are you using, I using smok and does not write back correctly.
