Context below is via use of a aarch64 snapshot image dd'd to USB3 media and use of a microsd card to hold the EDK2: # uname -apKU FreeBSD generic 15.0-CURRENT FreeBSD 15.0-CURRENT #0 main-n267507-a61d2c7fbd3c: Thu Jan 11 06:26:30 UTC 2024 [email protected]:/usr/obj/usr/src/arm64.aarch64/sys/GENERIC arm64 aarch64 1500008 1500008 # gpart show => 40 249737136 mmcsd0 GPT (119G) 40 2008 - free - (1.0M) 2048 249733120 1 efi (119G) 249735168 2008 - free - (1.0M) # mount -onoatime -tmsdosfs /dev/mmcsd0p1 /mnt # ls -Tlod /mnt/* -rwxr-xr-x 1 root wheel uarch 2031616 Jan 5 18:20:18 2024 /mnt/RPI_EFI.fd -rwxr-xr-x 1 root wheel uarch 76038 Jan 5 18:21:50 2024 /mnt/bcm2712-rpi-5-b.dtb -rwxr-xr-x 1 root wheel uarch 388 Jan 5 18:18:24 2024 /mnt/config.txt # dmesg -a | grep -E "(sdhci|mmc)" sdhci_acpi0: <Intel Bay Trail/Braswell SDXC Controller> iomem 0x1000fff000-0x1000fff25f irq 3 on acpi0 mmc0: <MMC/SD bus> on sdhci_acpi0 sdhci_acpi1: <Intel Bay Trail/Braswell SDXC Controller> iomem 0x1001100000-0x100110025f irq 4 on acpi0 mmc1: <MMC/SD bus> on sdhci_acpi1 mmcsd0: 128GB <SDHC SC128 8.0 SN REDACTED MFG 04/2018 by 3 SD> at mmc0 50.0MHz/4bit/65535-block mmc1: No compatible cards found on bus # more /mnt/config.txt armstub=RPI_EFI.fd device_tree_address=0x1f0000 device_tree_end=0x210000 # Leave RP1 PCIe configured on hand-off. pciex4_reset=0 # Force 32 bpp framebuffer allocation. framebuffer_depth=32 # Disable compensation for displays with overscan. disable_overscan=1 # Force maximum USB power regardless of the power supply. usb_max_current_enable=1 # Force maximum CPU speed. force_turbo=1 > BTW i did put some stuff here [1] > I could not get bcm_dma to work anyone planning on getting that to work? it should be similar to 2711 documented in [2] > >>> This does not have working PCIe or ethernet yet - I think ethernet ought to work since we seem to have a matching driver in the tree in dev/cadence. >> Sounds like the same status as booting just ACPI with no such >> adjustments too bcm2835bcm2835_vcbus.c or sdhci_fdt.c ? >> >> I think Mike Karels plans on investigating getting Ethernet >> going based on cgem .
