Replied to the thread J-Link RTT Viewer requires Disconnect / Reconnect.
PostNot sure if you understood Fabian’s post… “Sinply pulling nReset” is something that can disturb a debug (and so RTT) session. Pulling the reset pin may also reset the debug interface and cause a connection loss. Even if it does not, it may cause… -

Replied to the thread [SOLVED] Unlocking MKV30F64VFM10 using J-Link using known backdoor key.
PostI do not specifically know the KV30 into much detail but have worked on many of the various Kinetis flash algorithms for J-Link. For all Kinetis I have encountered, the debug interface does not provide a way to get the backdoor key into the chip. The… -

Replied to the thread [SOLVED] Jlink not 'disconnecting' properly.
PostAre you serious? You are wondering that something prevents your target from entering low power modes after you KILL GDBServer and so do not even give it a chance to perform a clean shutdown & clearing debug bits that very possibly may inhibit low power… -

Replied to the thread Transition from J-Link Edu to J-Link Mini Edu.
PostIs the target a 3.3V one? If not, that’s the culprit, as the EDU Mini does not have level shifters and therefore only supports 3.3V debug signals. Another thing is TRST. Not sure if the AM33 59 needs that pin… BR Alex -

Replied to the thread [SOLVED] 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…
