altera_msgdma with unaligned access: lost data and stuck busy

Hello, I've developed an application on a Terasic DE10-Lite board which has a MAX10 and an SDRAM chip onboard, using Quartus 18.1 for this. In my design I have used a nios II/f core (w/o cache), the...

Hi,


Could you provide the whole design file for duplicating?

There're some software library files missing.


Thanks,

Regards,

Sheng

Hello Sheng,

sorry for the delay, I've cleaned up the software files and left only what is needed for the test to compile.

My setup is a bit "twisted", you will likely need a copy of the toolchain, I've attached it. I had to modify the Makefile to have it work under WSL (to escape paths), and there is a patch for the bsp makefile (it removes 2 source files) under the buffering folder.

If you start with a clean bsp, then I'd start with

patch ../buffering_fast_bsp/Makefile bsp_makefile.patch

The toolchain is compiled to use picolibc and it is used for both the BSP and the test application, so you'll have to copy the file Software/buffering/picolibc_custom.specs to the BSP directory (as I've done under buffering_fast_bsp).

I've run make clean_all to clean all the build files, I think you can use the BSP I've provided and not bother with all that above.

The toolchain was compiled under ubuntu 22.04, it is not static linked.

Cheers,
