J-Link: Unable to download program

[JimmieJimmie]

Hello,

I'm using Eclipse CDT Neon .3 Release 4.6.3 with the plugin GNU MCU C/C++ J-Link Debugging 4.1.5 with a Renesas RZ/T1 target (R7S910018_R4F). Unfortunately I'm not able to download the program to the FLASH, here is the output log:

The problem is: "ERROR: Verification of RAMCode failed @ address 0x24000000." The J-Link uses RAM at the address 0x24000000 as work RAM. The CPU I'm using has no RAM at this address, so the access to this address fails. How can I setup the work RAM range in the plugin? According to the this article .gdbinit file is not loaded by the plugin. Instead the command should be added to the commands filed of the GDB client setup in the debugger tab. I've tried adding monitor WorkRAM = 0x00000000-0x00000000 to this command field, but it leads to another error:

Error in final launch sequence Failed to execute MI command: monitor WorkRAM = 0x00000000-0x00000000 Error message from debugger back end: "monitor" command not supported by this target. Failed to execute MI command: monitor WorkRAM = 0x00000000-0x00000000 Error message from debugger back end: "monitor" command not supported by this target. "monitor" command not supported by this target.

I've tried loading a settings file using the -settingsfile command line option of the JLinkGDBServerCL without success. It seems like the settings file is ignored. I've added the command monitor WorkRAM = 0x00000000-0x00000000 to the Initialization commands field in the startup tab. This worked for a few downloads and then stopped working. The address 0x24000000 is still accessed and leads to the above error. How can I specifiy the work RAM are for the J-Link debugger in the plugin?
