Hi Tcer, Quote: “And now I am succeed in debugging IMX6Q when I canceled the option of eclipse. I check your offical website and find there are so many amazing functions on J-LINK.” Good to hear that your are up and running again and thanks for the "flowers"! Quote: “But, I am afraid these funcitons might a little expensive for me, since I am just a college student in China who are hardly able to increase the budget on this project.” Please note that many functions of J-Link can be used free of …

Hi Forum, we fixed this issue internally. A official version of the J-Link software which fixes this issue will be available in a few days. Best regards, Niklas

Hi, correct. Does it work for you? Best regards, Niklas

Hi, I would suggest the following two tests using J-Link Commander (JLink.exe): 1. Connect to target by executing >connect< 2. Test if download to RAM works using the >testwspeed< testwspeed 0 3. Test if executing code from RAM works This can be done by any routine, a most basic one would be: C Source Code (2 lines) Memory can be writen using the >w4 <Addr>, <Data>< command. The commands >g<, >h<, >s< can be used for go, halt and step (or e.g the "TestHaltGo" command) in order to test if halt/go…

Hi, Quote: “As I mentioned in an earlier post the Zedboard you'd tested with is a different board from the ZC702 eval board although they both share the same Zynq processor. Perhaps I need to make some modifications.” Looking forward to hearing of your results! Are you refering to this board? xilinx.com/products/boards-and-kits/ek-z7-zc702-g.html Unfortunately we do not have this board in our collection of reference boards. Best regards, Niklas

Hi Jon, Quote: “Although it is not prompting me for a licence, can you confirm it is covered.” Quote: “OK - so now I've specified hex file, its asking for a licence” Is this still open? Which application is asking for a license? J-Flash? Best regards, Niklas

Hi Forum, this issue was solved in another thread: [SOLVED] Jlink edu only detects ATSAMS70N21 when connected to SAM-xplained board with ATSAME70Q21 Best regards, Niklas

Hi, thanks for the feedback and good to hear that you are up and running! Best regards, Niklas

Hi, depends on the target device and level of security. E.g. on NXP Kinetis devices the and ST STM32 devices the security settings can always be accessed / read via the debug interface, as long as the pins of the debug interface are not disabled. Best regards, Niklas

Hi SPR, you need to implement SEGGER_RTT_LOCK() SEGGER_RTT_UNLOCK() and disable interrupts and threads which might use RTT in SEGGER_RTT_LOCK() and enable them again in SEGGER_RTT_UNLOCK(). SEGGER_RTT_LOCK() SEGGER_RTT_UNLOCK() are already called by default in RTT, but the function bodies are empty and need to be implemented according to your setup / use case. Best regards, Niklas

Hi, "Via SFR access" means that the CPU is started via the debug interface by writing to a SpecialFunctionRegister. Best regards, Niklas

Hi, thanks for the feedback and good to hear that you are up and running! Best regards, Niklas

Hi, NJTRST is not necessary to halt the device. Please refer to the interface description for further information. Does it work in J-Link Commander (jlink.exe)? Best regards, Niklas

Hi Forum, this issue has been resolved via mail and with a firmware update which ships with the J-Link software & documentation pack, as usual. Best regards, Niklas

Hi, while the EDU mini can measure VTREF (in contrast to J-Link OBs which just show 3.3V), it can not adjust its output voltage. Therefore, it can only work reliable with ~3.3 Voltage targets. 1.8V and 5V targets can work by chance, but there is no guarantee. Quote: “ On SEGGER's homepage it says, that the J-Link EDU mini has the same functionality according Cortex M as the J-Link EDU.” This relates to supported devices etc. We will update the website to make this more clear. Best regards, Nikla…

Hi Masa and Forum, this issue should be resolved in the current version of Ozone . Best regards, Niklas

Hi, please find attached the J-Flash project I used. Its a auto-generated project, I just added the JTAG configuration via the "detect" option in the "Target Interface" tab of the project settings. Best regards, Niklas

Hi, Quote: “when my code are using other MCU peryferials: gpio, uart and radio.” Is it possible for you to isolate the code which is causing this issue? Best regards, Niklas

Hi, i just gave it a try on a Zync 7020 zedboard, but could not reproduce any issue after setting RAM to 8KB: Source Code (307 lines) Since it works from Mentor Sourcery Codebench with J-Link for you, I am currently a little bit out of ideas.... Do you have any further thoughts on this? Best regards, Niklas
