29f200 b programming problem

[youssefi201]

goodnight my friends
I tried to program 29f200b (sirius clio 32) with smart pro x8 programer
I manage to read and erase the flash but when I try to write I have error message
I do not know is what I should shunt pin or lift any pin

[racin-snake]

you doing it on the board ?
if so temp write protect off and best done in an adapter just for the convinience its a lot less hastle
theres a pinout of chip in a post of mine maybe give you some clues
never tried one on the board so maybe someone will come along with some better help

[youssefi201]

thanx freind for your quick reply
non not in board and i use 44 tsop adapter

[racin-snake]

make sure all legs are clean and try sort of moving the adapter from left to right on the zif
sort of wiggle it a bit as sometimes during the build some laquer goes on the pins to dip side and give a bad contact also try temp right protect off

[mastaflex]

i think there is bad contact. try to clean legs and after earse , do a Blank check. you can not reprogram till eprom is not blank.

Did you manage to sort this out?

[youssefi201]

no i think probleme in programmers

[bonecrusher]

Where did you buy the adapter for the x8 from?could it be the adapter?

Hi
Use a liquid flux pen and clean the connector and pins. this solved my problem with my first use of my 44tsop adaptor.
liquid flux from alfa-fry tech are cheap per half liter.

youssefi201,

you are writing on the same chip that withdrew from the ecu?
try to make the recording in a new chip.

Im having a similar problem with a willem clone,using
44sop adapter,it reads the 29f200,plenty of data in dump but it wont clear the chip,any advice?

connection, connexions ,connexions

[the_riddler]

is the adaptor A-pc-board, or a Clamp-in-type,

if it is pc board type i had same issues, till i soldered chip to board, then worked fine.

Conection problems now sorted,thanks for the help

Glad you managed to sort it OP.

Out of curiosity, can a 29f200 be substituted with a 29f400 ?

I know the 29f400 can hold more data but if it were programmed with the data from a 29f200, would ecu work as normal??

Cheers.

Regarding pin out connection, 29f200 can replace by 29f400.
But I don't test at real application.

Thanks for the reply. I did check pinouts before posting and yes they are the same, just wondered if anyone has tried for real. Im gonna give it a go....and will post the outcome ;)

i have sucesfully swapped a 29f200ab for a bb
worked fine on sirius ecu (last resort )
but cars still running lol
