Thincar Pro st link flashing problem [SOLVED]

[sevo]

H all, i have been trying to flash my dongle with diagzone firmware but i can not connect it to the computer, when i press connect on ST Link Utility it says can not connect to target. I have followed the st link instructions for connecting the diagram as stated but still no luck, my st-link v2 programmer has a genuine st chip on it, i even ordered a new one and am waiting for it. I saw that some st link v2 clones come with geehy chip, not even STM32, and was wondering if with the fake ones will work. Any help and ideas are very welcome and highly appreciated. Thanks in advance
this is the dongle itself

on the picture you can see there is some glue, but i have managed to expose the pads carefully and solder some thin wires on them.
p.s i can not upload images for some reason

I have just the same problem with Mucar BT200

I have just the same problem with Mucar BT200

I think mine is also a brand of Mucar BT200

Yes,they are the same, only the shield is different

is your st-link with genuine STM chip or another type? Did you open it to see?

Hi. If you use original stlink and connected reset point on a board to reset pin on stlink you also should give 12 v to mucar 4 and 16 pin in obd connector

I have a green st-link with a different pinout, maybe you don't have the same pinout either. here is an example in the picture

Do you mean pin 1 on st link which is RST, the instructions says that Reset from board should go to pin 5 which is not a RST on stlink!
So you suggest that i connect reset from board to pin 1 then supply additional 12V to pin 4 on mucar and 16 on OBD ? What about the 3.3V still supply them as well or? And also pin 4 on mucar is SWDIO on stlink what about that connection? it would burn the stlink and can damage the pc if i supply 12 to these pins? I don't understand, can you give me a diagram, also where is 12V GND connected as well? or do you mean to connect the dongle to the car and try to flash it this way?

i was hoping that this is the problem as well, but when i opened my st-link all the pinout corresponds to the case, so no luck there

12 and gnd must be fed to the obd2 connector
the rest of the contacts on the board according to the instructions, the reset on the board must be connected to the ground for a while before the connection is established, to stop the processor

Если оригинальный st-link, то во первых необходимо правильно определить пины на которые нужно подключаться, во вторых подать 12 вольт на сканер обд2(4,5 пин - gnd, 16 пин - +12 ). А также 19 пин ст-линка нужно пустить на 1пин.

I wanna apologize, i should have made myself clear in the beginning that i have the small usb flash drive like st link v2 adapter like this:

I have ordered 2 more, one with genuine chip and one with Geehy chip on it just to test and be sure that mine is not the problem.

but while looking at the images i think i have figured it out, when comparing the two st link adapters, the pins do not correspond, i was trying to reset the board with pin 5 connected to my pin 5 as per the instructions but i realized when you said that it should be to gnd that on my st link pin 5 is SWIM and not gnd, but on the ones with other chip, not genuine pin 5 is gnd, thats why it works with them and not with me, the pinout i used is not the correct one... thanks so much everyone, i will test it these days and give feedback as i am away from home for a week won't be able to do it now. One more time thanks a lot!!! Really appreciate your help

То что вы показали это китайская самоделка, а вот это ОРИГИНАЛ

What you showed is a Chinese homemade product, but this is the ORIGINAL

You are absolutely right, while searching for a st link, i have discovered that even the clones come with fake chips, ( the clones have clones) because the chip used is not even STM32F1, but something else, thats why i said in my previous posts " the ones with genuine chip and with fake chip". And by the way it is really hard to find the original programmer, even from mouser, farnell etc. Thanks again for your help and clarification. Thats really helpful information for everyone.


UPDATE:
so i have managed to flash the VCI, bought diagzone and I am downloading the software now, really happy with everything so far, i hope that everything will work as expected, thanks again to everyone for your invaluable help!
