Porting Main_MiSTer to other ARM core

[andrezheng]

Hi everyone,

I'm trying to port the Main_MiSTer project to other ARM core(Raspberry Pi Zero W). I met some compile issue for below two variables in video.cpp.
extern uint8_t _binary_logo_png_start[], _binary_logo_png_end[];

I searched all the project files and found nothing. Could anyone please help tell me where are these two variables located? Which file? Thank you so much!

From what i gather, those are only symbols in object files generated from *.png files.
See https://github.com/MiSTer-devel/Main_Mi ... le#L77-L79

I have to ask: why do you want to run Main_Mister on another device?

Wondering that myself - Without the FPGA it won't even be abe to even draw the OSD...

I don't get the purpose, too.
Without FPGA and HPS-FPGA bridge on SoC, what can Main_MiSTer do?

This might be the reason : https://twitter.com/topapate/status/136 ... 56450?s=20

But OP will need to confirm.

5CSEBA6U23 costs around $200. That's why want to throw the De-10 Nano away. In replacement, I'll spend $15 to buy a Raspberry Pi Zero W or another ARM chip with Linux system. And spend less than $100 for Cyclone V 5CEFA7F23(150K LE) or Xilinx XC7A200T.

After I comment these two variables, the Mister Main can running on Raspberry Pi now.

Hi andrezheng,

It looks good for your porting. Your meaning is we can combine the cheap Arm board(Raspberry ...) and Pure FPGA board(K7 100AT/200AT ...).
It is a great idea.

Not to mention the faster ARM processor.

You know what would be cool? The a standalone FPGA running MiSTer cores on a motherboard that has a raspberry-pi compute module connected to the FPGA via pcie (for the memory sharing).
