I've put relevant public diagrams (from Broadcom's patents) here:hanzelpeter wrote: I have been searching on internet for overview of BCM SoC of raspberry pi but can't find something
The Bcm2835 contains a boot loader/rom image that loads bootcode.bin from SD (there are other paths as well).hanzelpeter wrote: I saw that raspberry pi firmware is now open-sourced, but there is still some BLOB as closed source.
And my question is where is this blob?. Also for OpenGL this libGLES is passing commands to GPU and some fimware in GPU is taking this commands and executing them. Can I get access to this firmware? Can this firmware be somehow downloaded and reverse-enginered?
What about BLOB that is loaded at boot of PI?
Your best bet may be to use the services exposed already in start.elf or the game stuff in the old loader.bin.DavidS wrote:I have very much enjuoyed playing with the VideoCore processors.
I can not find any information on how to get anything out to the disply. Has anyone figured this out yet? If so is there any documentation on this anywhere yet?
With no BOOTCODE.BIN there are no MailBoxes to simplify this.
