Doesn't boot on Zero W 2 #196

Closed TheSos closed 2 years ago

TheSos commented 2 years ago

Hi! I just got myself a Raspberry Pi Zero W 2 specifically for a project involving this and, as I was quite expecting. It does not boot at all, showing blank screen. The green LED that normally lights up stays off as well. I am willing to help debugging or even fixing this, just not sure where I can find any debug info or logs, as it doesn't display anything. Let me know, would love to help! Cheers! Sos

Hello, today I received my Raspberry Pi Zero W 2 and exactly same here! If I can help, let me know! Peter

TheSos commented 2 years ago

As an update, I confirm that the same SD card boots fine on Zero, but on Zero W 2 it sets the video mode and stays blank.

randyrossi commented 2 years ago

Rene has a development branch on rsta2/circle. He added support for the Pi Zero W2 only a few days ago. I'm not sure if he's done yet but I can try making the same changes on my patched (older) circle to see if that works.

That would be awesome, would love to test it out or help in any way I can!

randyrossi commented 2 years ago

Try this master build here:

http://accentual.com/bmc64/downloads/master

According to Rene's change, it should be kernel8.img being loaded. So if it doesn't work, try adding this to the config.txt file

[pi02] kernel=kernel8.img

Or remove kernel.img and kernel7.img from the SD card altogether. I'm not sure if machine switching will work yet.

If you have a serial adapter, we can debug boot messages by turning on the serial debugging.

Also, I didn't include the latest start.elf, bootcode.bin and fixups.dat which you should get here and overwrite the ones from the img/zip:

https://github.com/raspberrypi/firmware/tree/master/boot

They may have been updated for W2. But I don't want to put them into a release unless I know they work for pi2/3/0.

Ok it worked! I downloaded the build, unpacked the files and replaced the three firmware files and it booted on both Zero 1 and Zero W 2.

Note that it wouldn't boot on Zero W 2 unless I replaced the start.elf, bootcode.bin and fixups.dat.

PS. I dug out a Pi 2 B and a Pi 1 and the same SD booted on all of them, USB keyboard input working. I don't have a 3 to test, tho.

Thanks for that! Let me know if there's antyhing you'd like me to test! I misplaced my FTDI thingie, tho, so I won't be able to do debugging for now.

Cool. Does switching machines work?

Yes, it does! My screen complained about 50Hz, but still displayed and I was able to switch to NTSC machine.

rhester72 commented 2 years ago

Confirmed the updated firmware works well on the 3A+ as well, including switching to all machine types and regions. I think it's good for inclusion with 3.8.

Randy, sent you a private mail re: a good number of other fixes and improvements for consideration in 3.8...please take a look if you get a chance.

dantaipan commented 2 years ago

I tried this same approach and it is not working for me. I know my roms are good because they are working on a pi 2b. Is it possible something changed in the bmc64 master or the pi firmware referenced above since posted that might have broken this?

dantaipan commented 2 years ago

I got it working by copying all fixup*.dat and "kernel8.img" from the pi master. Not sure which of those actually did the trick but happy to have it working.
