Hi Vidar,
Looks like you may be missing some tools that need to be installed to build this branch. I tested a build in docker though and that worked fine, so I'd recommend that. From inside your poky directory, you run Zachary Miller

Hi Zach
I started from scratch, cloned the repositories, changed KERNEL_PROVIDER and run the build script, but I got some error messages: V J

Hi Vidar,
If you pull @meta-cl-socfpga@ I've just added a recipe to build the 4.9.76-ltsi-rt kernel.
In @meta-cl-socfpga/conf/machine/mitysom-c5.conf@ just change @KERNEL_PROVIDER@ to be @linux-cl-socfpga-ltsi-rt@ and yocto will bu... Zachary Miller

Hi
We have successfully built the rocko branch (https://support.criticallink.com/redmine/projects/mityarm-5cs/wiki/Yocto_for_MitySOM-5CSX), but we need the PREEMPT_RT kernel.
4.9.76-ltsi-rt seems to be the one that matches the 4.9.78-l... V J

ZM 09:48 PM FPGA Development: RE: FPGA programming

Hi Davide,
If your FPGA is based on the one from the support site (in particular, if it includes PIO cores), you'll need to rebuild the kernel with the GPIO driver as a module instead of built in.
You can follow the instructions at... Zachary Miller

Hi everyone,
I'm having troubles programming the FPGA from HPS in the Linux environment. In particular, after I scp my rbf file to my sd card and disable the bridges, I try to program the FPGA issuing the dd if =file.rbf of=/dev/fpga0... Davide Vaccaro
