--14c89338958c44b2becf7e73c4fe3f16 Content-Type: text/plain I personally don't have any JTAG equipment, but happened to have a USB TTL cable lying around. At this point, both Jari and I have working SD access, and I just managed to do a successful UFS install to eMMC and got a booting system, so at this point I think local-style development over serial is actually workable! I initially tried a ZFS install, and while installation succeeded, the eMMC (hardware) module started throwing errors when booting from the resulting ZFS root. It's possible Jari's clock support might fix that, I'll have to try later. I don't have a spare eMMC module lying around to see if it's just the physical module. -Colin On Tue, Oct 10, 2023, at 12:57, Tomek CEDRO wrote: > Folks did you try to play with JTAG in order to upload kernel intro RAM and boot? :-) > > OpenOCD states initial support for RISC-V Debug Spec 0.13. > > Without Smart Debug Probe that supports RISC-V it could be slower than current loading from SD card though. > > Just curious :-) > > -- > CeDeROM, SQ7MHZ, http://www.tomek.cedro.info --14c89338958c44b2becf7e73c4fe3f16 Content-Type: text/html Content-Transfer-Encoding: quoted-printable <!DOCTYPE html><html><head><title></title><style type=3D"text/css">p.Mso= Normal,p.MsoNoSpacing{margin:0}</style></head><body><div>I personally do= n't have any JTAG equipment, but happened to have a USB TTL cable lying = around.
