Replied to the thread Flashing 1.8V target boards with J-link mini edu.
PostThe EDU mini is not guaranteed to work with 1.8V targets, only with 3.3V ones. BR Alex -

Replied to the thread Stange problem when using two Jlink units.
PostSounds strange... Is it possible that the USB hub, the J-Links are connected to, is not powered externally or its external power supply is broken? This would cause the hub and all J-Links connected to it to be fed from the USB cable that goes to your… -

Replied to the thread Possible bug in L1 / L2 verification or RP2040_M0_0.
PostAgree or not, your choice. Fact is: All J-Link flash loaders are designed to work with the natively memory-mapped space of the chip. For the RP2040 this is 16 MB, according to the datasheet. This means, J-Link will be able to program & verify 16 MB of… -

Replied to the thread Possible bug in L1 / L2 verification or RP2040_M0_0.
PostHi, If the memory-mapped region supports max. 16 MB, this is what your flash loader does support as well. All our flash loaders support max. what is mapped in the address space of the MCU. So what you describe is not a bug and no, we have not… -

Replied to the thread RTT doesn't work on RM48 - "RTT is not supported for this setup".
PostWhile RTT Stop-Mode in general might be working for the J-Link you use, stop-mode support on the RM48 may require further features that are specifically needed for RTT on RM48 in general, but these are not provided by the J-Link in use. In general, the… -

Replied to the thread [SOLVED] Segger RTT via Telnet.
PostNot sure what you mean with “There must be a simpler way”. What do you have in mind? Can you describe the “simpler” setup you have in mind? As RTT goes through the debug interface, you need an active debug session that does all the RTT handling… -

Replied to the thread Test Automation and GUI-Server Issue.
PostHi, Does the latest version still show these effects? V7.90 is from August 2023 (while we are currently in Feb 2024) and there have been several updates since then. segger.com/downloads/jlink/ BR Alex -

Replied to the thread How to program a PIC32MX?.
PostEven more unfortunate that you did not mention the exact device in use in the first place and that you were missing support, but instead let us guess and invest time into an answer that you already knew / probably expected... However, I invested some… -

Replied to the thread RTT timing.
PostAs the bottleneck is mainly the debug interface, USB3 probably gives a bit of better performance over USB2 in this discipline but if it is significant or even crucial, is something only you know. I do not have any USB2 vs. USB3 RTT comparisons at… -

Replied to the thread How to program a PIC32MX?.
PostHi, Well, you need to pass the correct name to J-Link… Not all devices share the same algorithm and flash size, so J-Link needs to know which device it is talking to, in order to have the correct algorithm selected. List of valid device names for…
