Hi,I'm running a baremetal application to write and read a byte of data into the DDR memory. The attached image shows the configuration of the DS-5 debugger being used. The error log is as shown: Stopping running target Altera - Cyclone V SoC (Dual Core) on TCP:localhost on connection Connected to running target Altera - Cyclone V SoC (Dual Core) on TCP:localhost Execution stopped at: S:0x3FF84E5C source /v "D:\Altera\embedded\ds-5\sw\debugger\configdb\Scripts\altera_target_check.py" S:0x3FF84E5C LDR r3,[pc,#188] ; [0x3FF84F20] = 0xFF706FFF No SYSID registers could be found.

No compilation unit matching "C:/Users/Administrator/Documents/DS-5 Workspace/app_test/Debug/test.c" was found Am I missing anything in the configuration? Is there any specific jumper settings? I suspect the problem is initialization of the memory but not completely sure on it. Please advice on this issue. Thanks in advance. I am using a Cyclone V Arrow SocKit with Quartus 14.1 edition. The preloader and uboot were generated through the bsp-editor after the system was generated through Qsys. Best Regards, Nitin.
This problem was solved.The semihosting should be turned on for the debugger to recognize the code for execution. Adding this line into the application code would resolve the error. More information about semihosting can be found here: http://infocenter.arm.com/help/index...054209469.html The error ERROR(CMD16-TAD11-NAL33): appears sometimes since the system is not reset. Either doing a reset through the debugger/powering the board off and on should be able to resolve this. Hope this helps for others facing the same issue. Cheers, Nitin.

I get pretty much exactly the same error messages you got, and am trying to debug a bare metal FPGA + NIOS2 + ARM system on a rev.D VEEK-MT-SoCKit. The FPGA and NIOS2 portion seems to be working just fine, but the ARM/DS-5 stuff not so much. I have tried with different preloaders (boot from QSPI/SDMMC/none) and debugger scripts (semihosting on/off etc.), to no avail. This is really starting to p**s me off, I think this entire procedure could and should have been made much simpler. Help would be much appreciated. TIA! BTW, the link you provided does not work.
hello moggiozziI can't understand that what kind of change I have to make in spl code. FYI I want to test DDR3 - HPS interface using a bare metal debugging. "OR 3) Initialisation scripts used precompiled version of u-boot-spl. You have to build your own version of SPL and replace it in project direcoty (or adjust makefile). In my case I add little changes to spl code that he completed after hardware initialization."
I have fixed this error in different projects by adding the peripheral description as a .tcf file to the DS-5 project. It also hit me in linux debugging if I removed the SysID peripheral from the hardware.
