OSSC (DIY video digitizer & scandoubler)

yes, it still launches your 1.20 fw that is installed by default.
(I changed the display text so that's how I know its still the other firmware. If I just compile my firmware and install it normally [without using oss2 on create_fw_img] it works on slot 1).

If your new firmware utilizes flash for anything else than FPGA bitstream (e.g. CPU instruction memory like vanilla 1.20 fw), then you also need to update platform desiger, linker scripts etc.

ah ok, that explains it. So its a lot of work because everything must be patched to look at the new firmware location offsets (of the 2nd firmware) instead of the default ones.
I suppose there is no config variable that makes this automatically right?

I made a new branch called "alt_fw" and the required updates should be in its latest commit.

Thank you! I'll try it out and report back

Edit: it worked just fine! Thank you once again
Btw one easy thing I did was to generate a patch for this single commit and apply/revert it on a copy of my branch to generate the 2nd firmware (of course I had to recompile everything including create_fw_img, but worth it).
