If you have a current J-Link that is in the support & maintenance period, we recommend to get in touch with our support team. segger.com/support/technical-support/ From what I read here, it could be a 3rd party security software running on that machine,…

You should check 2 things: 1) Make sure that you are using the 32-bit version of Raspberry Pi OS if you are using the "Linux_arm" version of J-Link. If you are using Raspberry Pi OS 64-bit, you need to use the "Linux_arm64" version of J-Link. 2) The…

Has a fair chance of being a DWARF 5 problem as well (not sure what DWARF version IAR V9.10.2 uses). I will push the DWARF 5 support internally, as this is going to be a growing problem, the more compilers are using DWARF 5 by default.

Flasher shares a lot of APIs and the DLL in general with J-Link. So the log file entries will say JLINK_xxx no matter if a J-Link, Flasher or J-Trace is connected. Regarding the rest: See previous post. This thread will be closed, as the original…

You can connect pin 1 to the 3.3V output of the adapter. Alternatively, you do not connect pin 1 at all but use this: wiki.segger.com/J-Link_Commander#VTREF and use the value “3300”

What has caught my attention is the line: VTarget = 2.720V Is the target expected to work with 2.7V signals on the debug lines (SWCLK, SWDIO, …)? 3.3V or 1.8V sounds like common target voltages but 2.7V sounds a bit odd. If this is a 3.3V target, the…

I do not see any confirmation that this guy was really using a J-Link and I doubt it. Fact is that J-Link never supported SPC chips. It was Flasher only since day 1.

No. PowerPC (at least some derivatives) is only supported by Flasher PRO.

If you reduce the SWD speed to let’s say 2 MHz or even 1 MHz, does it become stable? I do not know the exact parameters out of my head but it is very possible that the V8 does not do exactly 4 MHz but more something in the league of 3.2 - 3.9 MHz…

Pin 19 of J-Link is a 5V output. This needs to be converted to 3.3V for your target as supply voltage. At the same time, J-Link needs the target reference(!) voltage on pin 1 for its level shifters. This pin is an input to J-Link. You cannot power your…

Actually Andy, what would really help is some cooperation. I did not really ask for a working dylib but more for a reproducer to solve the original problem, as we could verify the fix immediately with your dylib instead of sending preliminary versions…

Would it be possible to DM / otherwise send us your plugin as an unsigned *.dylib? BR Alex

Closed because it is a duplicate of: Power Board w/Segger JLink Plus Compact

Without knowing the board, I would say: Yes, it is the safe way to disconnect the battery / take it out of the socket.

If you have an < 5V board, you need an adapter between J-Link and board if the board should be powered through J-Link: segger.com/products/debug-prob…rs/target-supply-adapter/

There is no on-board converter on the J-Link but an adapter may be used: segger.com/products/debug-prob…rs/target-supply-adapter/

There is no “getting” back here… Did you notice the difference between your 2 screenshots? Screenshot A) Shows the sectorization for the internal flash of an STM32… device. It clearly says “static sector layout” Screenshot B) Shows the…

Good point... We will add some logging for XML file parsing, especially in error case. These outputs will be part of the J-Link log file, they will *not* be output on stdout. wiki.segger.com/Enable_J-Link_log_file

I have no idea what you are trying to tell us with your latest try... I took a Mac Book Pro + J-Link PLUS + J-Link Commander: forum.segger.com/index.php/Att…33b07e8b5795e9b9188c79fd1 If you see an output like this, the J-Link is properly detected by…

If your target works with 5V and consumes less than 300mA, you can power it via pin 19 of J-Link. Supply specs: segger.com/products/debug-prob…#technical-specifications see "Target supply voltage" and "Target supply current". How to enable the 5V…
