Just because a standard allows it, it does not have to make sense to do it. It makes system bus access only half-way useful and not really a replacement for access via the CPU. So far *all* other implementations we came accross so far have implemented…

Hi, No, you are not correct. If you write a open flash loader for this, you can use J-Flash. It is just that we do not have such a loader available out-of-the-box for your setup. BR Alex

Hi, What you are using is a NAND flash. NAND flashes are not memory mapped accessible, so you need a customer flash loader to access them (for read & program). While memory mapped parallel CFI NOR flashes are somewhat standardized reg. their command set…

We used a different memory offset because we did not have your target in house. We also currently do not see why the address of the instruction should have any effect. However, we will check. Can you please let us know what connectors and what pinouts…

If it was working before, you have probably flashed something into the MCU that inhibits debugger connections. Are you working with an eval board or custom HW? If custom HW: Do you have connected the reset pin of the MCU to J-Link? If not: Can you…

Hello, We investigated and discussed this internally. With the current build setup and adding support for the J-Link GUI applications under Linux ARM also, we had to drop ARMv6. For now, there are no plans to bring it back because ARMv6 based Raspberry…

Hi, VCOM cannot be used in parallel to JTAG. If you use SWD instead of JTAG, you can use VCOM in parallel. Reg. the big connector: How about this? segger.com/products/debug-prob…rs/10-pin-needle-adapter/

Hi, Thanks for bringing that to our attention. Actually, the software is build on ARMv8-A based systems (Rpi 4). However, it was not intentional to break ARMv6 support for the 32-bit version. We will check that. BR Alex

The xc command is probably not the correct way. GDB Server is basically a translator from GDB to J-Link and takes care of the flash programming on certain memory writes. ELF file loading etc. are all more GDB things. Maybe this is of any help: …

EraseSector() must only return when the erase of the sector is complete. The timeout is a value that must not exceeded by an EraseSector() call.

How much current does your board draw? Did you make sure that it is within the specs of J-Link? Did you make sure that you have connected J-Link to a USB hub that has its own power supply? If not: Did you make sure that J-Link is the only device…

Hi, Can you please provide the full Python code, command files etc. you are using to get RTT data from JLink.exe? If this is an issue on our side, we need some more information about the exact setup and what exactly should happen, according to the code.

What device (manufacturer and device name) are you using?

Can you please describe what exactly you are doing? - Starting nrfjprog.exe to program the device - Exit nrfjprog.exe - Starting jlink.exe to do what? How do you get the RTT data? Do you connect directly via TCP/IP to a specific port? Do you instruct…

Hello, We are currently investigating an issue with TMS570LS devices and the latest CCS plugin. It is not related to the "The selected device xxx is unknown to this version of the J-Link software" dialog you are getting but may cause debugging to not…

Only one process can listen on a port. If you start nrfjprog.exe first, it gets the 19020 port, so it will be the default instance RTT Logger connects to. You either need to add a delay between exiting nrfjprog.exe and starting JLink.exe (otherwise you…

Thanks for confirming that it was an issue in your setup. Pulling the plug in the middle of the work is like getting your hands of the steering wheel of your cars when driving on a crowded highway and a high speed. There is a pretty high chance that you…

Hello, I understood it that way but thanks for summarizing to avoid misunderstandings. This does not change the fact that pic1 shows "V6.44b" in the message box title and not "V6.88". Do you agree? So the fact that the message box shows a version !=…

While we cannot comment on the compatibility to the board, the MCU should not be an issue. As you stated in the other thread, you can connect to the MCU via J-Link Commander (JLinkExe), it is proven that the EDU Mini is fine. If VsCode does not work,…

Currently, only [mA] is available and there are currently no plans to support anything else than probably [uA]. Accumulated power consumption: Currently not, but we will put it onto the agenda for the next meeting
