[-- Attachment #1 --] Hi, wanna give some heads up - conversation about this took mainly place in #bsdmips @EFnet and for a short time #FreeBSD-social @Freenode. I've posted the complete boot up here: https://pastebin.com/6HCFJRWD According to the Linux and /proc/cpuinfo, it says: --------------------------------snip-------------------------------- system type : MT7621 machine : Unknown processor : 0 cpu model : MIPS 1004Kc V2.15 BogoMIPS : 583.68 wait instruction : yes microsecond timers : yes tlb_entries : 32 extra interrupt vector : yes hardware watchpoint : yes, count: 4, address/irw mask: [0x0ffc, 0x0ffc, 0x0ffb, 0x0ffb] isa : mips1 mips2 mips32r1 mips32r2 ASEs implemented : mips16 dsp mt shadow register sets : 1 kscratch registers : 0 core : 0 VPE : 0 VCED exceptions : not available VCEI exceptions : not available --------------------------------snip-------------------------------- I've tried to build a FreeBSD12 along with a proper kernel, now Im stuck at loading the kernel via tftp in Uboot: https://pastebin.com/Ujx7t4SE Im not using compression, it seems the old U-Boot 1.1.5 only supports LZMA and using lzma from ports gives me a decompression error. As the paste says, Im using XIP (kernel in place) and trying to boot off 80001000, the 'md' output seems to be correct and that's where the bin also is located in memory. However upon start it just stucks and doesnt continue.... Im using a kernconf now which is inspired by the MT7621_FDT configuration, this seems to be not soo wrong as this seems to be the same chip. best regards, Georg Am 08.10.20 um 15:27 schrieb Kyle Evans: > On Thu, Oct 8, 2020 at 7:13 AM Georg Bege <georg@bege.email> wrote: >> Hello folks, >> >> Im trying to compile FreeBSD 12.0 for mips/mipshf and targetting >> specifically an mips 14kc CPU. >> >> I know this is not officially supported by any means, but I want to try >> it nonetheless. >> >> FreeBSD seem's to work on various platforms including a couple of MIPS >> families like 24kc. >> >> At least it's supposed to work on them... the device I have at hand is >> an EdgeRouter ER-X which is *not* an Octeon device. >> >> The steps buildworld seems to work fine so far, at least it compiles but >> on buildkernel I get an error upon linking: >> >> ld: unrecognised emulation mode: -Bdynamic >> >> It seems to come from an erroneous ld command which includes "ld -m >> -Bdynamic", which is obviously wong. >> >> I just dont understand why it is there :-( Im not super familiar with >> the inner details of the FreeBSD make files and building steps. >> >> Maybe someone can help me here... > 08:19 < kevans91> hmm > 08:20 < kevans91> actually, these are probably mostly legit > 08:20 < kevans91> You should still do a clean build, but that almost > certainly won't fix it on its own > 08:22 -!- Netsplit efnet.port80.se <-> se.hub quits: rap2, hugohagog, > @adalava, cognet, @dim, wkoszek, joneum3, > ganbold_, idwer, arrowd, (+23 more, use /NETSPLIT to show > all of them) > 08:22 < kevans91> DELAY is defined in mips/mips/tick.c, which isn't in > the standard sys/conf/files.mips because some > platforms have their own implementation > > So basically, you'll need to start building your own files.ERX to > include some of the stuff that isn't globally included; see, for > instance, sys/mips/mediatek/files.mediatek and copy the > mips/mips/tick.c line from that.
