Carprog Mcu Reflash Step by step

[tango]

if that dont work then leave pin 55 disconnected
then try
after reprogramming then connect pin 55 to gnd
all should be fine then

[Multipla]

after erase reconnect pin 55 to gnd
then reprogram mcu
mcu wont program if pin 55 is still connected to vcc

I did like you said, before pin55 vcc and afther pin55 and program, but nothing. unknown device.

[tango]

then do as i said in other post disconnect pin 55
reprogram mcu
connect pin 55 to gnd
now test

why do you need this ?
this os old fw 4.01
you would be better using the 4.74 fw

by the way !
Maybe configuration of segger project writes and read different sizes of content !
Because file to flash have 1,65kb , I read flash after write and segger read 616kb , if I read sectors to give 256kb file !
Another thing , some one say that Gnd pin isin"t was conected to nothing , Wrong !
check the pic

At88sc is semilar to 24c1024 ?!!
I use willem to read it and it give all FF FF FF.
I found AT88sc dump in web , but I try to write it and willem says "ACK comand error " same error as 24c02 is burn or dead

[tango]

you had no reason to try to read at88sc
its documented not to try to do this otherwise you kill the contents
only option for you now is to buy another carprog unit

struggled with carprog also reflash , brake leg on mcu , struggle then not regonise usb device then it works then it do not then antenna not work and next day it do , make rework all good then counter start again , time spend on struggle = could have bought 4 clones , from what i have seen once this thing starts with problems make a little rework to get basics running and order just main unit for replacement but most clones u get ver 4.01 and not happy make reflash jipee all good then struggle begin again = buy good quality online version clone and almost all problems at an end

Finnaly I could upgrade my carprog using an old PC with LPT and H-JTAG, no special programmer needed
When using LPT choose manual pins in h-jtag for LPT, configure by this schematic
Left pin 55 disconnected while programming, after the job is done, put it back on GND
100Ώ and 33Ώ resistors did the job

hello , solution from this thread is working also i was able to restore carprog antena for transponders. Now if your carprog reflashed , show you unknown device , first power up with 12v external supply , and after 20 sec connect USB cable.For me this is working so i'm another happy user . Hope is usefull for somebody .

Thank you all for your suggestions and unique experiences. A problem arose that when I connect my car prog to a computer, a message pop ups saying '' usb device is not recognized'' code 43. Any help please.
Thank you again for your valuable suggestions.

Hi, this is do to a problem of communication with your interface! first test or change the usb cable,if not pen interface and look for bad soldering point & or bad powering
(ther's a regulator for that),if also not resolved :so you can try to reflash your interface (look here in forum there's a step by step to do it),and finally if there's not a result :you must think to replace the mcu or the interface it self....regards
