I pulled down the latest snapshot produced by Jun Ebihara on 6th November. This boots fine on a Raspberry 1B & Pi zero but not on a Pi zero 2. The snapshot does not include start_x.elf and start_db.elf and associated fixup files so I used the 4 sets of start/fixup versions shipped with raspian and the system booted OK with start_x=1 in the config file. The good news is raspistill worked fine with the --nopreview option and I could capture a reasonable image OK. (if you omit the --nopreview option it succeeds in displaying the image but crashes shortly after) I tried to get it to take a sequence of still shots at a rate of 10/sec (using -tl 100) and that seemed to work OK, but after a while the kernel reports: dwc2_host_complete: unknown error status -54 a couple of times and then a slew of usb devices detach including the ethernet, keyboard etc. and that seems to be game over :-( Still at least its progress. I notice that there is an open source camera stack for Raspberry Pi using libcamera - might have a play with that under raspian and see if it can be ported to NetBSD. https://www.raspberrypi.com/news/an-open-source-camera-stack-for-raspberry-pi-using-libcamera/ Dave

I guess the calling sdmmc module doesn't like some of the data from the calls, tries to recover and fails. I'll try and understand the logic...

Thanks for the data point. I guess there may be significant differences in the microcode files between the RPI1B and RPI3b+, but at least the kernel loaded OK for you so the sdcard driver works. I have turned on debugging for the broadcom sdcard hooks and got a few hints as to where the problem lies - but need to look closely at the source to pin point the failure. Of course, even if I can get further I may still suffer the same crash with raspistill. FreeBSD works OK and I can get pictures, so I know it is achievable. Dave

Raspberry Pi camera under NetBSD current
I have been trying to get the raspberry pi camera to work on a model B under a recent current snapshot. NetBSD 9.99.88 (RPI) #0: Fri Sep 24 18:47:29 UTC 2021 mkre...@mkrepro.netbsd.org:/usr/src/sys/arch/evbarm/compile/RPI As standard booting off the sdcard works fine with the default config.txt, but to use the camera you need to modify this to add start_x=1 and set the gpu mem to 128. With the changed options you need different microcode files in the /boot partition start_x.elf and fixup_x.dat. NetBSD doesn't supply these, but I pulled versions from the git repository. The problem is that the system boots, but fails to attach the sdcard and thus cannot find root, Looking at the dmesg's from the two boots (screen shots for the failing one) it seems something goes wrong, but the error is poorly reported, A sort of diff between the dmesgs shows: -[ 1.00] total memory = 384 MB -[ 1.00] avail memory = 366 MB +[ 1.00] total memory = 128 MB +[ 1.00] avail memory = 115 MB -[ 1.00] genfb0: framebuffer at 0x5e6fa000, size 1280x1024, depth 32, stride 5120 +[ 1.00] genfb0: framebuffer at 0x4e6fa000, size 1280x1024, depth 32, stride 5120 [ 1.180396] sdmmc0: direct I/O error 5, r=6 p=0xc8733f14 write -[ 1.230495] sdmmc0: SD card status: 4-bit, C6 -[ 1.230495] ld0 at sdmmc0: <0x03:0x5344:SU08G:0x80:0x020d4db4:0x0c5> -[ 1.230495] ld0: 7580 MB, 3850 cyl, 64 head, 63 sec, 512 bytes/sect x 15523840 sectors -[ 1.240524] ld0: 4-bit width, High-Speed/SDR25, 50.000 MHz +sdmmc0: autoconfiguration error: can't get SD status 5 +sdmmc0: autoconfiguration error: mem init failed +sdmmc0: autoconfiguration error: init failed At first I thought the sdmmc0: direct I/O error 5, r=6 p=0xc8733f14 write message was the problem, but that appears on the successful boot as well. Irritatingly FreeBSD seems to work OK with the camera - but I really would prefer NetBSD. I can compile a kernel with some debugging for the sdcard, but thought others may have run into this problem Cheers, Dave
