Hello, I can not debug the NXP example project "hello world" for the IMXRT1050-EVK in the external SDRAM (IAR EWARM 9.10.1 in configuration "sdram_txt_debug") with a JLINK Plus probe. Debugging with the integrated DAP works as expected. The attached EWARM debug log forum.segger.com/index.php/Attachment/5282/ (using JLink V7.52d, also tested with V7.70c) shows several "Core did not halt after reset" entries and "Failed to read SP and PC from vector table at 0x8000'0000" but it also shows that the…

Hello, programming a simple hello world project (.mot) to our RT1020EVK with Macronix MX25L3233F QSPI flash instead of the default ISSI flash with JFLash v7.20 fails with the error message "Error while determining flash info (Bank 0 @ 0x60000000). I have attached the log output of JFlash to this post. If I use JFlash Lite v7.20 everything works as expected. Do you have any idea why it fails with JFlash while it works with JFlash Lite? Kind regards, Stefan

Hi Fabian, thank you we are already in contact with your support system so this thread is not needed any longer. Kind regards, Stefan

Hello, we are debugging our XIP project for IMXRT1020 in EWARM 8.42.2 with Jlink v6.7c (changing to a newer version does not help) at our own hardware. If we use the project debugger option "Auto" for Breakpoints we can set a breakpoint at a switch (exactly at the switch(....) statement) with 20 cases but we can not single step afterwards. If we try to single step a jlink "Reprogramming flash" window will open and be stuck at Erase 0%, Erasing range 0x60150000.... Compare is at 100% If we use th…

Hi Fabian, sorry I can not send you the project I'm working on and I don't know how to make a reliably not working example, but you are right the easiest and until now reliable working way is to switch the placement of the configuration structure to the auto-detect range. This solved my problem! I did not see a note on the website or in the user manual which mentions the auto-detect range of RTT Viewer. Maybe it makes sense to add this information somewhere on the website (e.g. with the supporte…

Hi Fabian, yes you are right if I specify the exact address for the control block it is working correctly. Using a range (you have to use the correct range e.g. OCRAM address range - that was my first mistake) works sometimes, but not always. For ease of use I still would like to find out why auto detection is not working on the new project, but for the old one it works. We are planning on using RTT for debugging and it would make it a lot easier to use if we do not have to type in the address &…

Hello, sorry to bother again. After changing to another project I have the same issues again. Could you please take a look at the log files I sent to you if it gives some hint on why the auto search is not working? We are using the IMXRT1020EVK with 2 Macronix MX25L3233F connected to FlexSPI Port A1 and B1 instead of the default ISSI chip. The Segger RTT Viewer configuration dialog is attached to this post. Thank you, Stefan

Hello Fabian, RTT is now working after some bugfixes (see my related post ). This thread can be closed too. Thank you, Stefan

Hello Fabian, thank you for the hint to open flashloader. I will take a look into that one. At the moment I have no other questions to this topic so the thread can be closed. Kind regards, Stefan

Hello Fabian, I followed the troubleshooting and J-Link DLL Update steps above and made sure everything is up to date (which it already was because I downloaded and installed the new JLink software a few weeks ago). I found some bugs in my code (flash access while configuring FlexSPI) which led to other undefined behaviour. After resolving them auto detection works. In case I run into reproducable problems with auto detection again I will open a new thread with a J-Link log file and RTT Viewer C…

Hello, if I set up RTT Viewer with a specific address for the _SEGGER_RTT control block the communication works while debugging with IAR EWARM. If I press the target reset button or redownload in EWARM the output in Terminal shows that it is connected to the exisiting Debug Session but the debug messages sent from target are not displayed in terminal until I disconnect and connect again. The output after a successfull connection to the existing Debug Session is J-Link V6.70c - Real time terminal…

Hello, I included Segger RTT in our IMXRT1020 firmware. If I specify the exact address of the _SEGGER_RTT control block in RTT Viewer Jlink is able to find the block and the communication works, but there is no Terminal output with Auto Search and Search Range. I tried - running to main, connecting RTT Viewer and run the code - run code to the address after RTT block gets initialized, connect RTT Viewer and run rest of the code - let the code execute and connect RTT Viewer while code is executin…

Hello, my question was already asked on this forum [SOLVED] writing i.MX RT1051 eFuses through J-Link The last post is already 1.5 years ago so I would like to know if there is any more information about programming eFuses with JTAG available since then? The Wiki search does not provide information about eFuse programming so I think there is none available right? Kind regards, Stefan
