Replied to the thread Erasing A Sector That Isn't In .bin File Via Command-Line.
PostHello, The -delrange command only affects the data file and not the chip itself. To delete only a specific sector via the J-Flash command line application, follow these steps: 1. Select the sectors in the J-Flash GUI application (currently not possible… -

Replied to the thread write in the flash in twice.
PostHello, The cause of the issue you are referring to is that the J-Link erases the whole sector before programming it. To resolve this issue, you can either: 1. Combine the data of the two .elf files into one data file and then flash this single… -

Replied to the thread Very inefficient flash writing process (on RT1170).
PostHello, Quote from mastupristi: “Reads take place byte by byte ” I took a quick look at the sources of our flashloader and did not see any issues that could lead to this. Quote from mastupristi: “At the end QE bit remains at 0 ” Our… -

Replied to the thread How to debug using J-Link edu mini along with NXP's S32DS.
PostHello, Unfortunately, we also have no experience using the NXP S32 Development Studio, so we recommend getting in touch with NXP about this. Here you can find a list of supported IDEs and how to use them with J-Link: wiki.segger.com/Supported_IDEs… -

PostHi, Quote from tinydrop: “I connect target device with swd (7pin 9pin 2pin) ” It should be: 7 - SWDIO 9 - SWCLK 1 - VTREF (not 2) 5 - J-Link-Tx (J-Link out => Target in) 17 - J-Link-Rx (J-Link in => Target out) One of the pins you mention is wrong. If… -

Replied to the thread Transition from J-Link Edu to J-Link Mini Edu.
PostHello, As long as the reset pin of the EDU Mini is correctly connected to the TRST of the evaluation board, you should be able to pull the TRST line high. Best regards, Simon -

Replied to the thread why jlink gdb server reponse "Unsupported CPU"?.
PostHello, The regs command is only supported for the ARMv8 AArch32 architecture. Since the Cortex-A55 is ARMv8 AArch64, GDB responds with "unsupported CPU." Best regards, Simon -

Replied to the thread JLink firmware and support/maintenance periods.
PostHello, When a new version of a J-Link is published, the old version usually continues receiving firmware updates for a few years. After this life cycle, the firmware updates are no longer developed, and therefore you can't update them anymore. You can… -

Replied to the thread [SOLVED] API OS_InInterrupt() doesn't work if called inside function called by OS SW timer.
PostHello, Thanks for your feedback. It's good to hear it's working for you. Yes, I would like to add such an API routine that returns the current context. Unfortunately, that would work for Cortex-M but not for all other CPUs. Anyway, I will add it to our… -

PostHi, thanks for quick reply Your explanation is very clear, and also help us in undertstanding better where OS timer SW are called ("Cortex-M embOS software timers are executed within the PendSV()") Your workaround seems works fine in my tests. I… -

Replied to the thread [SOLVED] API OS_InInterrupt() doesn't work if called inside function called by OS SW timer.
PostHello, This is not an embOS bug, but it works as intended. OS_INT_InInterrupt() returns 1 only when called from an embOS interrupt routine. From any other context, like embOS software timer, it returns 0. With Cortex-M embOS software timers are… -
