Hi Tom Thanks for the extra information. I was able to regenerate the HDF with (I think) the appropriate changes in the PSU UART configuration (just changing UART1 to MIO[0..1], is that all that is required?). I then (eventually) managed to get everything to build in Yocto using the new HDF by setting the HDF_PATH appropriately in my local.conf.
With the new boot.bin etc. I see the FSBL output now (a step forward) but nothing more - I guess U-Boot is not loading properly from the boot.bin? I am slightly confused as to why this is necessary. Manju from Xilinx said they have verified that it works but you are saying that the HDF provided by default in meta-xilinx* is incorrect - have I missed something?

Then it should be possible to regenerate the hdf file and drop it in the correct folder and run a new bitbake build. --Tom From: meta-xilinx-boun...@yoctoproject.org [mailto:meta-xilinx-boun...@yoctoproject.org] On Behalf Of Manjukumar Harthikote Matha Sent: Wednesday, September 26, 2018 11:17 AM To: Tomas Thoresen <tom...@xilinx.com>; simon.g...@doulos.com; meta-xil...@lists.yoctoproject.org Subject: Re: [meta-xilinx] Ultra96 UART Hi, Yes it should be psu_uart_1.

So, something like this: YAML_BSP_CONFIG[stdin]="set,psu_uart_1" YAML_BSP_CONFIG[stdout]="set,psu_uart_1" Hope this helps.

Following the various bits of guidance from this list I have successfully built, and have all the files I would expect in tmp/deploy/images/. The files do not seem to boot - or at least I don't see anything on the serial (via the Avnet serial to USB dongle for the Ultra96). I have read on another forum (http://zedboard.org/content/j6-serial-port-appears-not-be-working) that the default config of the FSBL for the Ultra96 board does not configure the UART properly and indeed using a 'hacked' boot.bin which has been 'fixed' from that forum entry I can boot the board and see output on the UART. My questions are: - Has anyone else successfully booted an Ultra96 using meta-xilinx/meta-xilinx-tools? - If so, did you see anything on the UART? Were any changes made to the FSBL configuration to achieve this? Any comments or guidance gratefully received!
