Oct 14 19:31:22 <litb> hello all
Oct 14 19:31:28 <litb> i got the zedboard
Oct 14 19:31:38 <litb> can I use the poky distribution with it? or do i have to use petalinux?
Oct 14 20:00:51 <Crofton> poky should work
Oct 14 20:01:10 <Crofton> you need to add meta-xilinx-bsp
Oct 14 20:39:28 <FrostEyes_P1> litb: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841883/Yocto
Oct 14 20:40:30 <FrostEyes_P1> litb: and you will typical start with repo and their manifest https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841862/How+to+build+images+through+yocto
Oct 14 20:47:45 <litb> FrostEyes_P1, i just built a poky image minimal for the zedboard
Oct 14 20:48:18 <litb> but i'm confused. why should I use petalinux instead of poky+whatever-i-would-need-for-xilinx ?
Oct 14 21:12:59 <Crofton> :)
Oct 14 21:13:01 <Crofton> exactly
Oct 14 21:22:44 <litb> Crofton, other folks on the internet say that I need to install a minimal fpga bitstream myself, which instantiates the PS7 IP and passes it the board's clock signal
Oct 14 21:23:09 <litb> however I couldn't find that on the official meta-xilinx's README
Oct 14 21:23:29 <litb> I would think they would mention this, if that's really true
Oct 14 21:23:38 <Crofton> meta-xilinx-bsp should have the ps7 files patched into u-boot
Oct 14 21:23:58 <litb> ah i see. so they include a minimal bitstream by default
Oct 14 21:24:34 <Crofton> no bitstream, just enough code to setup DDR MIO and a few other things
Oct 14 21:24:53 <Crofton> when you make a real design, you may ned to use your own ps7 files
Oct 14 21:24:58 <litb> i remember, i think it'S a ps7.c file with some lowlevel inits
Oct 14 21:25:03 <Crofton> right
Oct 14 21:25:11 <Crofton> the actual values are in .h
Oct 14 21:25:42 <litb> Crofton, but if i don't provide such a bitstream, the PS7 hard-IP on the FPGA won't get clock-signals and won't be connected to the DRAM-controller
Oct 14 21:25:54 <litb> how will this work without the bitstream?
Oct 14 21:26:05 <Crofton> TH FCLK"s you get some defaults
Oct 14 21:26:19 <Crofton> Zyng arm runs runs with empty bitstream
Oct 14 21:26:32 <litb> ah i see. nice
Oct 14 21:26:35 <Crofton> yes
Oct 14 21:26:40 <Crofton> very helpful
Oct 14 21:27:05 <Crofton> get it booting then worry about customizing
Oct 14 21:27:15 <litb> so what this guy says is incorrect: https://medium.com/developments-and-implementations-on-zynq-7000-ap/install-ubuntu-16-04-lts-on-zynq-zc702-using-petalinux-2016-4-e1da902eaff7
Oct 14 21:28:11 <litb> he could have installed the ubuntu without any bitstream aswell
Oct 14 21:28:47 <Crofton> I stopped reading when I saw Patelinux 2016.3
Oct 14 21:29:26 <litb> :p
Oct 14 21:30:52 <litb> I imagine when they connect things to M_AXI_GP0_ACLK and configure FCLK, this whole PS7-IP is just a dummy-IP in the diagram which gets translated into corresponding ps7.h values
Oct 14 21:31:02 <litb> like, calls to configure the PLLs
Oct 14 21:31:09 <Crofton> the platform init stuff has morpedh ove the years, but sedboard from meta-xilinx-bsp should make something that boots
Oct 14 21:31:19 <Crofton> (or it did last time I worked on it)
Oct 14 21:32:33 <litb> Crofton, i wanna get some experience in the embedded world. figured i would start with zedboard and riscv
Oct 14 21:34:27 <Crofton> damn it, need to send them a ptch to generate wks images to save screwing with sd cards
Oct 14 21:37:59 <litb> ah, that's what the wic tool uses to create bootable images
Oct 14 21:44:46 <litb> Crofton, maybe I will add it if it's not too difficult
