I can get ip and even ssh in on -current and latest u-boot, but yeah it's broken enough that i did shutdown my boards w/it, i know it used to do way more IRQs too. I don't know yet, nor really feel like it'd be worth my time to do anything than install something else on it, but it might be related that someone did fuckup the timers on it too, tick does around 66/update in systat, and stattick barely 100. fwiw., i got some fixes commited to u-boot for sun4i_emac, but otherwise it's unable to boot sd0a:/bsd w/bootarm.efi, so still broken&useless, it will be(U-Boot 2017.11). -Artturi > > U-Boot SPL 2017.03 (Apr 03 2017 - 11:14:00) > DRAM: 512 MiB > CPU: 912000000Hz, AXI/AHB/APB: 3/2/2 > Trying to boot from MMC1 > > > U-Boot 2017.03 (Apr 03 2017 - 11:14:00 -0600) Allwinner Technology > > CPU: Allwinner A10 (SUN4I) > Model: Olimex A10-OLinuXino-LIME > I2C: ready > DRAM: 512 MiB > MMC: SUNXI SD/MMC: 0 > *** Warning - bad CRC, using default environment > > In: serial > Out: serial > Err: serial > SCSI: SATA link 0 timeout. > AHCI 0001.0100 32 slots 1 ports 3 Gbps 0x1 impl SATA mode > flags: ncq stag pm led clo only pmp pio slum part ccc apst > Net: eth0: ethernet@01c0b000 > starting USB... > USB0: USB EHCI 1.00 > USB1: USB OHCI 1.0 > USB2: USB EHCI 1.00 > USB3: USB OHCI 1.0 > scanning bus 0 for devices... 1 USB Device(s) found > scanning bus 2 for devices... 1 USB Device(s) found > scanning usb for storage devices... 0 Storage Device(s) found > Hit any key to stop autoboot: 0 > switch to partitions #0, OK > mmc0 is current device > Scanning mmc 0:1... > reading /sun4i-a10-olinuxino-lime.dtb > 26581 bytes read in 30 ms (865.2 KiB/s) > Found EFI removable media binary efi/boot/bootarm.efi > reading efi/boot/bootarm.efi > 67436 bytes read in 42 ms (1.5 MiB/s) > ## Starting EFI application at 42000000 ... > Scanning disks on scsi... > Scanning disks on usb... > Scanning disks on mmc... > MMC Device 1 not found > MMC Device 2 not found > MMC Device 3 not found > Found 6 disks > >> OpenBSD/armv7 BOOTARM 1.0 > boot> > booting sd0a:/bsd: 3935884+166328+562136 [273417+90+522736+245831]=0x5785f4 > > OpenBSD/armv7 booting ... > arg0 0xc08785f4 arg1 0x0 arg2 0x48000000 > Allocating page tables > freestart = 0x40879000, free_pages = 128903 (0x0001f787) > IRQ stack: p0x408a7000 v0xc08a7000 > ABT stack: p0x408a8000 v0xc08a8000 > UND stack: p0x408a9000 v0xc08a9000 > SVC stack: p0x408aa000 v0xc08aa000 > Creating L1 page table at 0x4087c000 > Mapping kernel > Constructing L2 page tables > undefined page pmap [ using 1042532 bytes of bsd ELF symbol table ] > board type: 0 > Copyright (c) 1982, 1986, 1989, 1991, 1993 > The Regents of the University of California.
