.elf of updated build not downloading to Nios V from RiscFree

I have made a "hello world" project using Quartus lite23.1, RiscFree 24.3 on a Cyclone IV. The initial project works OK, but if i do an edit to the c soure file (hello world), the newly compiled elf...

    Thank You for Your reply.

    Things has made a weird turn to the better..

    I tried to recreate the situation before I did the edits in bsp_editor I mentioned in my previous post.

    I started bsp_editor, opened the settings.bsp-file, checked enable_alt_load and enable_alt_load_copy_rwdata and generated bsp_settings again.

    However, I did not get back to my previous situation. I was still in a situation where a reset would freeze the niosV, only a new run from RiscFree would get it running again.

    To get out of this situation, I tried to generate a new bsp rather than editing the old one.

    Voila:, everything works. If I edit the hello.c file, the newest version runs on then NIOS.

    I think I am now in the situation where the old proverb "If it aint broken, dont fix it" applies.

    We can consider this case closed.

    Unfortunately, when I regenerated the new setting.bsp the old one was overwritten, and it it thus not possible to compare working and non-working versions.

    Thank You again for Your help.

    Best regards

Thank you for your reply.

I have not had any progress lately.

1. I do not get any error messages when downloading new elf-file from riscFree. I have not been able to find any error message in any .log-file. It just does not give the NIOS the latest elf. Using niosv-download from niosv-shell works perfectly.

2. I do not know how to select reset signal after download option. I do not get an automatic reset after download, I need to do a reset from hardware (Push-button) to make the program on Nios to start running again. This applies whether I try to download from riscFree or using niosv_download. I have tried adding the -r option to niosv-download without sucess.

3. I do not know what boot method the nios is using? How do I tell and where do I change it?

Best regards
