Not exactly sure what the question is here... What you can always do is using J-Link to access the registers of the i.MXRT1062 QSPI controller and send custom sequences to the QSPI flash to make happen whatever you would like to happen. Unfortunately, I…

Hi, Such errors often point to connection / setup issues. It looks like J-Link either cannot write the RAM @ 0x1FFF8000 *or* the RAM is written correctly but reading brings garbage data. Some things to check: - Does it get better with slower interface…

Semihosting support for ARMv8-A AArch32 has been added in V7.64d: segger.com/downloads/jlink/#J-…twareAndDocumentationPack This does not include semihosting support for AArch64. As I wrote, there are no immediate plans to add semihosting support for…

Semihosting in general is possible on ARMv8-A targets (Cortex-A53 etc.). However, J-Link does not support it yet. We are working on AArch32 semihosting support for GDB Server which should be available in 1-2 weeks. There are no immediate plans for…

St‘s forum is a better place to ask, as it is their chip and their boot ROM. Most chip vendors suppress (certain) debug operations in boot ROM on purpose. BR Alex

Hi, Currently, chip erase is not explicitly available for this device. There are no immediate plans to add support for it. You may write your own flash loader, doing exactly what you want: wiki.segger.com/Open_Flashload…ending_an_Existing_Device You…

The FINE protocol supports 2 MHz max. and everything selected > 2 MHz will be scaled down to 2 MHz. 64 buffers sounds weird… SystemView is not designed to have information disteibuted over multiple buffers if they belong to the same instance. If you…

You could also get your hands on the J-Link SDK and write your own applications, adapt J-Link Commamder to your needs, … BR Alex

Hi, That's unfortunate news. Right now, there are no immediate plans to have a J-Link OB firmware image for the micro:bit V2.20. I will update this thread in case plans change. BR Alex

Does J-Link Commander from our software package detect this J-Link? If yes, we are back to the point where you need to contact Microchip, as a working J-Link Commander proves that the USB connection is fine and it is more probably an IDE issue. We are…

Hi, Microchip Studio is not listed on the “supported IDEs” page and untested. Therefore, we cannot guarantee that it works. No matter if it worked under Win 10 or not. We recommend to contact Microchip regarding this. This is actually the wrong…

Thanks for trying. Then it is a bug in GDB Server. Will be fixed in one of the upcoming versions. I recommend to sign up for the notifications. segger.com/notification/subscribe.php?prodid=7

It’s probably a bug. If you do not use the monitor command but use the GDB commands “info registers” “info all-registers” instead, does it work then?
