    Quote from japa: “I am using Cortex M4 EFM32 Pearl gecko chip (EFM32PG12B500F1024GL125) to write and read a configuration file using J-Link Commander ” I don't really understand what you mean by that - please explain further. A diagram might…

    Post
    Hello, Thank you for your inquiry. J-Trace PRO will currently buffer instruction trace data up to 64 MB (depending on your target device this can be more or less than 67M datapoints). We are currently working on expanding Ozone and J-Trace PRO so you…

    Hello, Thank you for your inquiry. Correct, different data channels would be trace pins, trace buffer and SWO. Only one can be evaluated at a time. But ETM and ITM packets can be channeled through the trace pins at the same time. This has to be…

    Hi, I gave it a try but on my end seems to be ok. I tested with both, V5.44 and the most recent one V5.50b. Attached are some screenshots. Unfortunately, I don't have the same font, so I can not say if this is related to the font. I used Noto Sans…

    My design includes one Edit and two keyboards( alphabet keyboard and digital keyboard). The intention is when Edit is clicked, one of the two keyboards appears. One type of keyboard can switch to another type by clicking the "abc" or "123" button. The…

    Posted the thread Ozone ETM trace limit.

    Thread
    Hello, It seems there is a hard limit on the captured instructions. In my case, the number of instructions is limited at around 67M, even though I set "Maximum instruction count" to 10G. I wonder if this is a hard limit or something configurable…

    Posted the thread Jlink SDK ETM and ITM support.

    Thread
    Hello, I need to capture both ETM and ITM trace at the same time. If I understand correctly, if trace pins are used, both ETM and ITM data are routed to J-trace. However, in the manual of Ozone, it is state that "The simultaneous use of multiple trace…

    Replied to the thread Copy rect / Bitblit operation.

    Post
    This surprisingly worked, it's just super slow. I used GUI_BMP_SerializeEx() to copy a rect from the frame buffer then draw it using GUI_DrawBitmap(). I may have done something wrong here that I'll have to play around with. C Source Code (17 lines)

    Newbie here. How would I go about doing a bit-blit type operation? I've got some text drawn over background that is constantly changing (game display), and I need to redraw the background behind the text when it changes. I was hoping something simple…

    Hi, I am using Cortex M4 EFM32 Pearl gecko chip (EFM32PG12B500F1024GL125) to write and read a configuration file using J-Link Commander. While doing this process, I erased the internal flash memory of the chip using "erase" command. Is there any way by…

    Post
    Hello, Thanks, I must have missed that in the release notes so we'll give it a try. We're still testing 4.18 since it looks like the embedded version of GCC had a major point change and we're seeing some perf loss.

    Post
    Hello Giacomo, Thank you for your inquiry. That data can only be accessed with a J-Link EDU if the target device has an MTB or ETB implemented. In all other cases a J-Trace PRO would be needed to capture the ETM data that is streamed out of the trace…

    Thread
    Dear all, do you know if J-Link EDU can be used to access data stored within ETM? From the documentation, it is clear that J-Link EDU does not support tracing of ARM M-series, but the question is whether it is able to access data stored within ETM, also…

    Hello, Thank you for your inquiry. With the latest Embedded Studio V4.18 you should now have the pre build option as a solution option as well. Could you give it a try? Is that what you were looking for? Best regards, Nino

    Hello, it is nothing wrong with your dialog. The WM_CREATE message is for simple windows. For dialog windows you should use the WM_INIT_DIALOG message instead of WM_CREATE. Just change it in your callback _cbLoading(). Also you should call any…
