Ds-5 debug on Arria 10 Reflex Alaric board.

Hi,

I appreciate that this my not be the right place for this post as its not technically an Altera product.

I did try Reflex first but they just said they do not support Bare-Metal development & pointed me back at Altera.

I have recently taken delivery of this board & I thought I'd start with a simple Bare-metal Hello World test.

I took the same project that I had used on the Arria V SOC but built using the aria-10dk-oc-ram-hosted.ld linker script.

I then updated the DS-5 debug config to use Arria 10 SOC/BareMetalDebug/Debug Cortex-A9 0.

On trying to load the image over the USB-Blaster I got the following error:

stopping running target altera - arria 10 soc on tcp:localhost on connection

connected to running target altera - arria 10 soc on tcp:localhost

warning(cmd407): trying the entry point instead

error(cmd426): cannot find symbol to start or entrypoint, the file or load commands may be used to set the entrypoint

wait

In fact Ds-5 cant read any addresses in the oc-ram space.

On checking further the only memory I seem to be able to access is 0xC0000000 – 0xEF7EFFFF (HPS-to-FPGA).

Could this be a BootRom issue?

Any help would be gratefully received.
