Re: [meta-xilinx] [xilinx-tools] Why does it require Rocko?

Hi Geoff, Historically this layer has worked regardless of Yocto upstream changes, the reason is that it is dependent on Xilinx tools rather than Yocto OE-core changes. One of the recent changes that happened in Thud was device-tree.bbclass, which impacts the device tree generation. We have

Hi Jean, Ok you are right. This would be needed for cases where you are using the same build directory for multiple release builds Thanks for the patch Thanks, Jaewon -Original Message- From: Jean-Francois Dagenais Sent: Thursday, March 21, 2019 8:33 AM To: Jaewon Lee Cc: Manjukumar

Re: [meta-xilinx] Really bad SD/eMMC performance after upgrading 2018.1 to 2018.3

Mike, although I have not made any measurements I have noticed in the last few days (coincidentally I have been doing a lot of work with a ZCU102) that the SD interface seemed a bit slow. Are you seeing this on Zynq 7K or US+ MPSoC? Best Regards Peter On Thu, 21 Mar 2019 at 16:38, Mike Looijmans

[meta-xilinx] Really bad SD/eMMC performance after upgrading 2018.1 to 2018.3

The SD and eMMC controller has become terribly slow in 2018.3: # echo 3 > /proc/sys/vm/drop_caches # dd if=/dev/mmcblk0 of=/dev/null bs=1M count=20 20+0 records in 20+0 records out 20971520 bytes (20.0MB) copied, 4.972666 seconds, 4.0MB/s # dd if=/dev/mmcblk1 of=/dev/null bs=1M count=20 20+0

Re: [meta-xilinx] [PATCH] xsct-tarball: use fetcher cache

Hi Jean, Just tested this again, as long as the tarball is there in downloads, it will not redownload. If it starts with a fresh tmp directory, xsct-tarball will reextract to tmp/sysroots-xsct, but will not redownload tarball Please check again Thanks, Jaewon -Original Message-
