**** BEGIN LOGGING AT Sun Oct 14 03:00:00 2018 Oct 14 15:24:24 New news from stackoverflow: yocto raspberrypi showing default splash instead of raspberrypi splash Oct 14 16:54:41 New news from stackoverflow: Kernel selection using yocto Oct 14 17:54:52 New news from stackoverflow: Running a Qt App on imx8 fsl-imx-xwayland DISTRO Oct 14 19:31:22 hello all Oct 14 19:31:28 i got the zedboard Oct 14 19:31:38 can I use the poky distribution with it? or do i have to use petalinux? Oct 14 20:00:51 poky should work Oct 14 20:01:10 you need to add meta-xilinx-bsp Oct 14 20:39:28 litb: https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841883/Yocto Oct 14 20:40:30 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 FrostEyes_P1, i just built a poky image minimal for the zedboard Oct 14 20:48:18 but i'm confused. why should I use petalinux instead of poky+whatever-i-would-need-for-xilinx ? Oct 14 21:12:59 :) Oct 14 21:13:01 exactly Oct 14 21:22:44 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 however I couldn't find that on the official meta-xilinx's README Oct 14 21:23:29 I would think they would mention this, if that's really true Oct 14 21:23:38 meta-xilinx-bsp should have the ps7 files patched into u-boot Oct 14 21:23:58 ah i see. so they include a minimal bitstream by default Oct 14 21:24:34 no bitstream, just enough code to setup DDR MIO and a few other things Oct 14 21:24:53 when you make a real design, you may ned to use your own ps7 files Oct 14 21:24:58 i remember, i think it'S a ps7.c file with some lowlevel inits Oct 14 21:25:03 right Oct 14 21:25:11 the actual values are in .h Oct 14 21:25:42 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 how will this work without the bitstream? Oct 14 21:26:05 TH FCLK"s you get some defaults Oct 14 21:26:19 Zyng arm runs runs with empty bitstream Oct 14 21:26:32 ah i see. nice Oct 14 21:26:35 yes Oct 14 21:26:40 very helpful Oct 14 21:27:05 get it booting then worry about customizing Oct 14 21:27:15 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 he could have installed the ubuntu without any bitstream aswell Oct 14 21:28:47 I stopped reading when I saw Patelinux 2016.3 Oct 14 21:29:26 :p Oct 14 21:30:52 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 like, calls to configure the PLLs Oct 14 21:31:09 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 (or it did last time I worked on it) Oct 14 21:32:33 Crofton, i wanna get some experience in the embedded world. figured i would start with zedboard and riscv Oct 14 21:34:27 damn it, need to send them a ptch to generate wks images to save screwing with sd cards Oct 14 21:37:59 ah, that's what the wic tool uses to create bootable images Oct 14 21:44:46 Crofton, maybe I will add it if it's not too difficult **** ENDING LOGGING AT Mon Oct 15 03:00:01 2018
