Dear Skip,
That pushed the ball forward significantly, but I still have issues. (But thank
you, every little advancement helps.) So with that flag, I was able to get
Richard’s port to boot into Glenda’s account (showing acme, faces, stats, etc).
However, I do not seem to have any USB; no mouse;
I took that microSD card that has the bootable image without USB and put it
into a traditional Pi4. It boots on that without a problem and has mouse and
keyboard. I notices that after the additional CPU cores are detected, that is
mentions usb/hub… usb/kbd…. The image when booting on the Pi 400
sorry to keep asking,
a couple of years ago you gave me a technique for stopping part of usb and then
restarting it with debug turned on (done from a usb keyboard).
i have a new compact keyboard from ebay but it is not seen by plan9, and not
listed in usb/probe; though it does work with MacOS
Hi,
I didn't test Plan 9 on my RPi 400 so far, but I think the reason for the USB
problems
is the following:
The Raspberry Pi 400 (along with the Compute Module 4 and the 8 GB RAM version
of the RPI4) uses a new stepping C0 of the BCM2711. This version does not have
a
dedicated EEPROM for th
Might as well note here that the USB on the CM4 is the USB-C on the
4B. A found (just now) forum thread confirms that the CM4 actually
has an XHCI and just doesn't expose it at all. Nothing on this in the
datasheet.

Can you netboot Linux followed by netbooting Paln9 and have a working USB?

However, I just checked Richard's kernel source and it seems the firmware
loading functionality
is already included, there is a call to
xhcireset(BUSBNO(hp->tbdf)<<20 |
I did try to boot into Linux and then d a soft reset into Plan9. Still the same
thing, no USB. I tried booting from the on-board card slot, and then as I soft
rebooted, swapped out the card. As well as booted Raspian off of a microSD
adapter and after booting, put the plan 9 card in the on-board
I built the 9pi4 kernel from Richard's sources and it works on my Pi400 (and
Pi4B 8GB)
with Richard's SD card image (didn't test 9front).
Please feel free to test it, I uploaded the kernel to:
https://multicores.org/9/9pi4
(simply copy the file to the FAT partition of the SD card)

USB boot is supposed to work on pi400 as well so I thought there would be no
need for any firmware loading

Here's the config.txt that I use for my rpi400 (it's on the file server and
handed to rpi via tftp):

fixup_file=fixup4cd.dat
cmdline=xxx/cmdline.txt
kernel=arm/9pi4
gpu_mem=16
hdmi_group=2
hdmi_mode=82
