Dear community. Could you help me figure out with jlink setting for the following setup ? MCU LPC4088 Memory layout has been attached. I want to use Ozone and elf file for debugging. Thank you in advance.

Hi AndyR, please refer to the Ozone user' manual, section 4.6.1, where the hardware requirements for the data sampling window are listed. There you can see that you can control background memory access emulation via the system variable…

JLink RPM package for Linux provides /etc/udev/rules.d/99-jlink.rules file which allows to use SEGGER devices without root access. This file also contains the following line which skips processing of rule entries for devices which are not handled by …

you can't graph watched variables when using the emulated background JTAG refreshing [ Cortex A5D27 doesn't support high speed live watches according to ozone so is starting and stopping the MPU to read the values ] they do happily slowly update which…

Hi fraengers, thank you. We will try to reproduce and come back to you. This might take a while since all engineers are currently fully booked. Best regards -- AlexD

Hi AndyR, I'm sorry but I am not able to comprehend the point of your inquiry. Could you please describe more clearly what exactly you would like to know or understand? Best regards -- AlexD

Is there flash loader config available to read/write iMX6 external flash? eMMC/NOR?

given you can refresh watched data at up to a few Hz in the background on MPUs that don't support the full high speed sampling mechanism over JTAG, why does the Timeline / data sampling? using J-Trace with Cortex A5D27 which doesn't support the full…

Hi, Re-reading this old post I read about “SetFlashDLNoRMWThreshold”, so I said to myself, “Why not try this as well?” I modified the script like this: Source Code (4 lines)And works!!! Now you can help me answer the question, “Why does it work?…

Hello! Is it possible to read write i.MX6 external NOR and emmc flash with J-Flash? As far as I understand some extra definition files is needed?

Hello, I try to write 0xFF to WorkFlash of Traveo2 MCU to avoid the ECC error by using J-Flash. But I got verify error after write 0xFF to WorkFlash. (See attached JFlash.log line 151-158, 302-309) Test case1 : All WorkFlash area is 0xFF. address…

Hi Trying to link very simple aes risc-v code and falling on the linker phase : error: undefined symbol __SEGGER_RTL_X_get_time_of_day referenced by symbol gettimeofday (section .text.libc.gettimeofday in file timeops.o…

When executing J-Link_Commander script what's the proper way of retrying operations? Currently I use: Source Code (10 lines)and use it with JLink.exe -NoGui 1 -CommandFile production.jlink Is there a better/faster way? Like if conditions, retry…

Hi, I'm trying to program a MX66L1G45G spi flash on a custom board with an ATASAMA5D27C microcontroller. I have a SEGGER "Flasher compact" connected to the board. When I try to create a new project in the J-Flash V8.10b tool, I can not find a suitable…

Thanks for posting this Steven, and I hope SEGGER can find some time to update the J-LINK for micro:bit V2.2x. I've run into this as I've begun some development in this area, and though completely new to embedded systems engineering, suspect that most…

Hello, for a RISC-V simple executable project , I am encountering an "illegal instruction" error when using 'aes32esi'. The code compiles without any errors, but the error occurs at runtime. SEGGER setup: - arm_assembler_variant = "SEGGER" -…

I've got a jlink connected to a mcu. Was running a long duration test, connected through jlink ultra. Was communicating through RTT from laptop. After 30 hours or so, the middle led turned red. Was unable to communicate anymore. I plugged/unplug the part…

Hi, we have a bit of a problem with FWs larger than 57344 bytes (0xe000 in hexadecimal), that run XIP from flash, and we connect to CM4. We were also able to reproduce the problem with an example SDK (which I attach) on MCUXpresso IDE v11.10.0 [Build…

Thanks, Thomas! All good for me, then. I am looking forward to the update, but we can use JRun as is in our test environment.

Dear wonderful Segger Team, Could you please support the STM32MP253 - STM32MP2537 family please? Best, Alexis
