Hi, I just tried to create a licence for use with Nordics nRF devices but the licence I got back is for 'Cortex-M V5'. That's very kind but not quite what I wanted, and it doesn't have the nRF specific bits and pieces in it. Did I do something dumb? How do I go about turning this into a nRF licence? Regards DAVE

Hi, On V6.84a with JTracePro cortex (I think it also happens with JLink Pro) and streaming SWO when the probe is physically disconnected the SWO channel is continually flooded with old data. Easiest way to reproduce is to connect to the SWO output of JLinkGDBServerExe using telnet or similar and then when the application is running just unplug the USB connector on the JTrace. The channel floods. Regards DAVE

With this new version, using GDB Server, after an initial 'load' of an elf, 'start' or 'run' for the first time will result in a target disconnect. Restarting GDB Server and gdb allows normal operation thereafter. I cannot recreate the previously observed issue at the moment. Regards DAVE

Hi, Current release (V6.62a) and Beta (V6.63b) will not program my device which is on FlashSPI alternate config. Reverting to V6.56d fixes the issue. Interaction sequence is attached. I cannot send the hex file because it's too big for the forum but you can send me PM and I'll send it to you. Regards DAVE Brainfuck Source Code (173 lines)

Hi there, Does JLink-Pro support VCOM over Ethernet? I don't see anything written one way or the other anywhere... Regards DAVE

Thanks...that fixed it. I figured the Beta would be newer than the release version and didn't look closely at the release :-/ Regards DAVE

I get 1 AFAIK there's nothing special I have to do in order to be able to _read_ from the TPIU.... Regards DAVE

Hi Nino, This is our own board and we've specifically brought out the trace pins to be able to use with the JTrace....which is a bit of a pain as they're shared with the Ethernet. I've PMed you my s/n and email address. If you could send me the source that equates to the PEX file for the 1050 that would be very helpful. What concerns me slightly is that in the TPIU registers (TPIU_SSPSR) it would seem that only one bit tracing is supported on this chip...so I'm hoping I'm mis-reading them. I've …

Hi there, My Code Profile window is corrupt for both 'Run Count' and 'Fetch Count', see pic attached. Is there any known fix for this? V2.61i on Ubuntu 18.04. Regards DAVE

Hi there, I'm trying to do parallel trace on an IMXRT1021 144 pin variant. I can only seem to get it to work for 1-bit wide tracing. When I try to set 4 bit (either via Ozone GUI or using a JLinkScript file with the line JLINK_TRACE_PortWidth = 4) I still only see single bit output from the chip (i.e. TRACECLK and TRACE0 are toggling) and, in this circumstance, I get no trace output. Is there something I'm missing here? I have setup the pins manually to support trace (ALT6 mode) with no differen…

Well, this one didn't get much love, did it? The answers to the questions are; JLinkExe does support the secondary pinmux (it's transparent to the debugger) provided you've booted through the ROM to configure the chip. To erase the flash you need to execute 'exec EnableEraseAllFlashBanks' before the 'erase' command. I can't say which chips it supports but it certainly works with the IS25LP064A as found on the 1021-EVK. What I haven't figured out yet is how to reflash the application from the GDB…

Hi there, I have an IMXRT 1021 144-pin version board with QSPI connected on the secondary pinmux option (i.e. BOOT_CFG[2:1]=111b). I cannot get the flash to erase or program in this configuration using JTrace and V6.43c. I don't see anything obvious wrong in my wiring or configuration. Is the IMXRT1021 flash utility set up to recognise the connection of the flash chip? If so, how do I configure it? If not, can it be added? Regards DAVE

Hi Nino, As noted I'm on a JLink Pro. I don't think it would be a good idea to post my S/N here but you can PM me if you need it. It's part code 8.12.0 and the number starts 17440... According to the documentation it should support baudrates 3.2x10^9/64 and below ...I've tried rates as low as 115.2kbaud. I can see the output correctly formatted on the scope but I cannot get the probe to recognise the flow correctly. The native speed of this chip (600MHz) is a bit higher than most CORTII so I won…

Hi Guys, I've got a JLink Pro connected to a IMXRT1052 board (The NXP EVB board, as it happens). I've got SWO output but I cannot get the JLink and the chip to agree on baudrates. The calcuations the JLink are doing seem to be a bit off....or I am misunderstanding something. According to the various output the base clock for this type of JLink is 3.2GHz and the minimum divisor is 64. I I try something simple like this; Source Code (20 lines) ...then the output is 14.8uS/bit, or 33.8KBaud. If I e…

After further testing I can confirm that this is indeed solved by means of pulling up the UART RX on the target. Regards DAVE

OK, I think I might have found this as I finally managed to get the board on a scope. I deliberately didn't put a pull on my RX (JLink TX) since I expected it to always be driven and it would just be a waste of electrons. However, It would appear that the JLink floats its TX pin after a transmission is completed...leading to corrupt reception due to confusion over start bits. Pull the RX high and the problems appear to go away. A little more testing to do, but I wanted to get this posted ASAP so…

I've sent an elf, plus a link to the matching source just in case it _is_ a problem in my code (which I don't expect you to debug...just for extra info). The code already filters the \0's. Here's the result of pressing <Enter> a half dozen times; Source Code (18 lines) Regards DAVE

Hi Niklas, Hmm, that's odd, but did you try the other extreme; i.e. sending a single character intermittently (as happens when you're using the Serial Link for a Command Line Interface)? That seems to be when the problem occurs. If you contact me via my email address I'll happily send you an image that you can load into the Nucleo and see if you can see the problem then. Of course that doesn't preclude it being a s/w problem on my side, but I don't see it when using a USB to TTL-Serial adaptor. …

No worries, just want to check I'm not doing inappropriate in the forum. I'll be at my desk so if there are tests you would like me to run please let me know. I'm on MacOS 10.12.1. Regards DAVE

Hmm...I'm new in here, despite having used JLink for a number of years, but mine is the only post with zero replies after a week. If I'm not following protocol and thus being ignored will someone please indicate why? AFAIK JLink on STM32 is a supported configuration? Regards DAVE
