I've been using a jethro build on a Zynq-7000 system. When I
create/build a Linux Application hello world project on Xilinx SDK
2016.3 and try executing it, I get "-sh: ./test.elf: No such file or
directory". I think this is because of a toolchain or rootfs library
mismatch between the Xilinx

I can disable it in my device tree with:
ps7_ttc_0: ps7-ttc@f8001000 { compatible = "invalid"; }
Does anyone know what TTC0 would be used for? Doesn't seem to be
critical as Linux stills boots and runs OK. Thanks for your help.

Thanks Nathan and Mike, I just installed the SDK from Yocto and the
Linux executables it generates are working fine.

I cross-compiled an application to run on Linux on the Zynq-7020.
Trying to execute it gives "No such file or directory" error.
# file app_hello.elf
app_hello.elf: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for
GNU/Linux
Is it possible to use Yocto to compile a Xilinx SDK project? Would I
use the Linux version of Xilinx SDK, or could/would I use some other
toolchain that's more command-line oriented? Could I furthermore
build a BOOT.BIN from, say, a Xilinx SDK-based FSBL and a Yocto
generated u-boot.elf? Can

And apologies for not mentioning my running in an AMP configuration,
but it did not seem related
the SLCR_LOCKSTA register for the lock status and unlock if
necessary. I tried to find in the kernel where this would occur, but
got lost in the kernel driver code.

this in it:
clock-names = "ref_clk", "aper_clk";
clocks = < 13>, < 30>;
The "30" in clocks is referring to gem0_aper, which looks out of place
in the clock tree (being under armpll instead of iopll).

My eth0 interface can only run at 1Gbps. If I plug into a 100 Mbps
switch or use ethtool to set the link speed, it looks like it
succeeded:

I'm using Zynq 7020 AMP config with Linux on CPU0 and FreeRTOS on
CPU1. ps7_i2c_0 is to be used by CPU1. What is the proper device
tree setting to use for ps7_i2c_0 in this case?
1) ps7_i2c_0: ps7-i2c@e0004000 { compatible = "invalid"; };
or
2) ps7_i2c_0: ps7-i2c@e0004000 {

I've been using linux-xlnx-dev.bb recipe to compile a kernel with the following:
PREFERRED_PROVIDER_virtual/kernel = "linux-xlnx-dev"
SRCREV_pn-linux-xlnx-dev = "3be00480727bf360d912223026b789011b1e5251"
This was pointing to a 4.0 kernel. Now, on a fresh build, I get
"unable to find revision"
