Hello everyone! This is my first post on the forum, but I've been using the Pi development page for a while, and it's helped me a lot. Since then I've made a good amount of progress, and I wanted to share what I've found:

This goes right after "_start:" in the ARM32 code and replaces the "mov sp, #0x8000" line. Yes, that's needed, because ARM32 uses 4 cores now too.Quote: I hope this helps people here! I would post it on the wiki, but since I'm new I wanted to get feedback first. I'm sure it will help people. I'd say go ahead, update the wiki. We always welcome contributions!Cheers, bzt |
