JLink V8

[wild]

buy the J-Link EDU ORIGINAL one!
The difference of price is not so high compared to the clones (no warranties at all).
Latest HW version of the original is v11.
I do not suggest to buy the EDU mini because is much slower.

[rajhlinux]

Thanks for replying, would you happen to know where I could buy V11 original edu?

All edu original starts around $63 before shipping and tax.

Also, I could take the EDU original and convert it to the regular J-Link version, right? By flashing the firmware?

[wild]

I do not know where you live, but you can find J-Link EDU at least at Digikey, RS, Mouser, Adafruit, ...
From what I know, there are NO differences between EDU and regular one. Just you have to get rid of the once a day nag screen.
On RS the total price is 70 Euros, Shipping and taxes included (22% VAT here in Italy)
On Digikey is 71.55 Euros (shipping and taxes to Italy included)

Attached you can find a link for model comparison. edu and base is pretty much the same. On edu version you have also unlimited breakpoints. You don't have J-Flash license, which is included in jflash plus, so you can't use jflash utility, but you can do debug and program internal flash of MCU

the official Jlink looks as if the price has increased.
but my understanding of the regular version and the edu, was they are the same.
to buy and use the edu version was on trust. they issue a note saying not for commercial use.

J-link V10 Firmware,

[nik80]

any idea how to remove "features" added with "exec addfeature flashbp" for example?
its a genuine j-link v8 ARM where I added some "features" and now the latest commander say its defective probe
it seems "addfeature" add any string there, and I did type it all lower case, may be that is the reason

edit: just tried "exec clearfeatures" which still doesnt work but show different error, it write only "ERR"
edit2: downgrading the firmware with j-link ARM 4.20 made "exec clearfeatures" work, now that field is empty, but cant add features anymore, it says "ERROR - Too many features"
any ideas?

[nik80]

thanks for your suggeston
what you mean reflash?
firmware update through segger (already did it, still same error) or the same instructions for unbrick with RST and TST pins?
what is the chance if I fully reflash with firmware for clone to be recognised as clone some day later?

[nik80]

Im really sorry for my stupid question, and thanks for your time, but could you please tell me which way is that "flash to default" ? may be a link to instructions?
I know only 2 ways - through segger configurator there is 2 options - firmware update/firmware replace (both doesnt fix the problem)
and the other way is with RST and TST pins to fully erase the device and then flash with sam-ba and firmware downloaded from internet, which definitely erase SN and many other things

[token0]

the other way is with RST and TST pins to fully erase the device and then flash with sam-ba and firmware downloaded from internet, which definitely erase SN and many other things

iirc, the second way is valid, in the end you need to connect "default" j-link to your pc and set your serial via j-link commander, like that:

choose your usb
> usb 0
and set desired serial (if it's genuine, then it's real sn is written on the bottom)
> exec SetSN=58012345

[nik80]

I can see that this is the procedure for clones, flash and replace SN, but some people say that after a while they are bricked by segger software, and need to repeat again
what is the possibility that genuine device with genuine SN later to be recognised as clone if I flash it with different firmware downloaded from internet?
its the yellow IAR j-link arm v8, Im not using it regularly, from once a month to once a year, and I really dont want next time when I plug it to be bricked

[pickit2]

clones are not as far as I have heard being bricked, for a few years, even when they were it was a easy fix.
as It;s been said 'if you have a genuine unit, it has the serial number on the label' or read if from the software when you connect.

or rise a ticket with segger support.

[nik80]

I had some spare time today, and tried
after few attempts and no success with 2 different firmwares downloaded from different places (one cant make connection, the other still show defective) I had to edit the bin file to remove all licenses, one that definitely trigger "defective" is RDDI wich was included in one of the bin files, it should be removed, and the other is GDBFULL, it should be only GDB I think
so to be safe I did remove them all and then added manually later in commander, now it seems to connect properly with no errors or warnings, in the next few days I will try to connect to real device, to check if still work as programmer/debugger

[Ahmad_k]

Does anybody know if I have the J-Link EDU and I used the keygen to add a license for JFlash, will this work ?

[h0nk]

Hello Ahmad_k,

> will this work ?

Yes.
You can check Your licenses with "JLinkLicenseManager.exe".
But the software will still ask their daily question.


Best Regards

I was searching for those chinese clone J-Link v9 or above, can't find any store other than Aliexpress (blocked in my country). All source found have prices near the genuine EDU version, so I think it is better if I choose the genuine if the keygen is working.

If Anyone have have a source to buy clone v11 I will appreciate it.

I was using it for a couple of years. I want to upgrade to a better one

[vico]

Hello,

I got JLINK V8 from Aliexpress in picture below.



Is it possible to upgrade to V9? How I can do that?

[baybay]

v8 and v9 hardware completely different, so it is not possible

Simple fix for the latest JLink 7.70

JLink_x64.dll file offset 0xCC238: 90 90 90 90 90 (the original here is E8 53 87 FF FF)

This is for 64bit only and it should remove the procedure for clones. Tested to work fine with a JLink V8 clone.

If I have time, I will see what needs to be done also for JLinkARM.dll to be used for 32bit

Did you have to time to do the 32 bit version?
Or the latest 7.82C?

[yahoo]

Did'n have time but checked now for a few seconds I see that on file offset 0xB3D6D (original e8 7e 85 ff ff) must have 90 90 90 90 90. Talking about the latest version 7.82c file JLinkARM.dll for the 32bit support.
Not tested but it must work. Let me know if not.

[yahoo]

For the latest JLink_Windows_V788a_x86_64.exe the file JLink_x64.dll fix is at offset 0xC81D4: 90 90 90 90 90.
I just ordered V9 clone from aliexpress to replace my old JLINK and it will arrive by the end of the month. Is there somebody using V9 and can confirm this patch is good for V9?

[tomywong]

Yes, it work on my Jlink v9 clone. Thx.

[fonak]

Hello,

Patch works ok with jlink v9.46 and v11.  

The only problem is constantly reporting the need to update the Jlink clone firmware in the Keil environment.

Does anyone know how to disable it, or update the firmware to such a version so that the message does not appear anymore?

Regards
