ARMDS cannot see source code in debugger

Hello

I have an ARMDS_IDE debugger that works on Cyclone V EVB,

I compiled PRELOADER and UBOOT using Quartus 18.1 and trying to debug the preloader code until reaching the UBOOT script processing. (ELF)

Unfortunately, the Intel/Altera part seems to be fine.

Cyclone V identifies the HPS as the first element in the JTAG chain (USB BLASTER),

The CPU halts and its registers and memory can be seen through the ARMDS IDE. The CPU can be reset and controlled by the JTAG connection and the ARMDS, the JTAG clock speed is 16M.

Unfortunately, the source code (C and H) cannot be seen as expected.

Switching Toolchains and locating the corresponding folders in "Debug Options" setting, did not help.

I will appreciate if anyone could assist in this issue, so it will be possible to use source level debugging.

ARMDS2020.1 and 2024.1 shows the same behavior.

Thank you in advance
