    Posted the thread JLINK_PIN_Override() conflicts with JLINK_JTAG_WriteIR().

    Thread
    Hi, We are using JLINK_PIN_Override() when perform unlocking of Secure JTAG on Cortex M7 (NXP iMX RT1050) To unlock Secure JTAG Controller (SJC), we need to set JTAG_MOD=1, then perform some actions, then set JTAG_MOD=0 But we can't keep HIGH level on…

    Thread
    I am trying to use JFlash with a Flasher ARM to setup a cortex M4 board with Kinetis K64. I have a script that works with a different brand flash programmer. I am trying to use MCU Init Steps to duplicate the script actions. The script sequence is…

    Post
    Hi Nino, Thanks for the reply. The watchdog is regularly feeded (every 32 seconds). To prove this the firmware works just fine (without the watchdog resetting the module) when the debugger is connected, that is the problem I am having. As soon as the…

    Hello, Thank you for your inquiry. The described behaviour is expected. To handle a watchdog you can either disable it or you need to feed it regularly. How is described in the target devices reference manual and numerous Arm coding guides. Best…

    Hello, Thank you for your inquiry. The auto unlock may only work if reset is connected. This does not seem to be the case here. Check if your board has the reset line connected. Best regards, Nino

    Thanks for your quick reply Nino. I changed the RTT compilation to include the ASM RTT_Write() routines. Unfortunately Sysview does not seem to be measuring the correct length of the ADC-DMA, being a factor of 6 or so out. Should be measuring 0.5ms but…

    Hello, Thank you for your inquiry. We were not able to reproduce the warning with the EVB boards we got form NXP. However they have engineering samples on them so it is possible that these values have changed in the actually shipped cores. We will order

    Posted the thread Programme Serial Number with J-Link EDU.

    Thread
    Hi Segger team, I have been reading lots of forum threads about how to programme serial number for production and I don't see it clear. Is it any way to set the serial number with a J-Link EDU or is it imperative to have a J-Flash License?. Is there a…

    Hello, Thank you for your inquiry. SystemView uses RTT for I/O so to get an idea about what overhead to expect you can check out our RTT page: segger.com/products/debug-prob…about-real-time-transfer/ The typical overhead is ~1 µs per event for a CPU…

    Thread
    Using the Jlink tools v 6.52 under MacOS, I'm scratching my head how to unlock a Microchip/Atmel ATSAMD21J18A... The "unlock" command isn't right, as it only supports other chips. I tried just "erase", and that also doesn't work. What am I missing…

    Replied to the thread LISTVIEW - different styles.

    Post
    I've found a work around. I've created 3 columns in my listView, and played with the content placing negative, so I could move it to the left, outside the defined column width. should be a nice feature, to define a style class on a listview row :)
